While hemp’s CBD content has been the primary driver in its recent resurgence, interest in its use as a textile fiber also still persists. doi: 10.1080/15377880801898691. Another example of co-localization is the QTLs for contents of xylose and glucuronic acid. The use of molecular markers has several advantages, including the early stage selection of promising plants. This gene was mapped in the scaffold53823 where both QTLGlc1 and QTLKL1 are located. doi: 10.1074/jbc.M511598200, Ranalli, P. (2004). doi: 10.1016/j.indcrop.2007.05.003, Vannozzi, A., Dry, I. A crop grown specifically for fibre will generally produce a higher quality product than a dual-use crop. When markers non-affected by population structure and were correlated with r2 equal or above 0.1 (∼r ≥ 0.3), they were hypothesized to be physically close on the same chromosome. At a threshold of r ≤ 0.3 (∼r2 ≤ 0.1) the number of QTLs and explained variance remained mostly steady, while at r > 0.3 (∼r2 > 0.1) the number of QTLs and the explained variance dramatically increased (Supplementary Table 2). Briefly, six cell wall traits [contents of glucose (Glc%dm), glucuronic acid (GlcA%dm), mannose (Man%dm), xylose (Xyl%dm), acid detergent lignin (ADL%dm), and Klason lignin (KL%dm)] and one fiber parameter (BCD%) were measured after harvesting the stems. 44, 821–824. Varieties of hemp, whose stems are used for fiber, bio-fuel, or other products, grow to 6-7 feet in height, providing the desired long fibers for industrial processing. This baseline value of r2 (< 0.1) was set as a threshold to identify non-random associated markers. For those markers involved in genetic relatedness processes, genetic drift and selection can create linkages between markers, even if they are located in different chromosomes. Only biallelic markers were selected, the frequency sum of the two major alleles was equal or above 95%. The X-axis indicates the physical distances and the Y-axis indicates the pairwise correlations (r2) between all pairs of markers from the scaffold. Hemp can be grown for fiber, seeds, and/or for dual purpose in a wide range of geographic zones and climates. doi: 10.1038/ng1702, Zavaliev, R., Levy, A., Gera, A., and Epel, B. L. (2013). The Hemp fiber or industrial hemp is obtained from the outer layer or the bast of the Cannabis sativa plant, more popularly known as that meant for producing marijuana or hashish. To estimate the threshold to discriminate between collinear and non-collinear markers, a study of pairwise correlation-distance between markers from the same scaffold was performed. This creates a snowball effect by lowering the cost of purchasing the separation equipment, … 1-800-995-2339 Customer … The genetic structure of marijuana and hemp. Table 3. Dense plantings (as many as 300 plants per square yard) help ensure that the plant grows straight. To date, only three genetic association studies have been performed in hemp and they focused on sex expression and cannabinoid content (Faux et al., 2016; Grassa et al., 2018; Laverty et al., 2019). The lignin polymers hinder decortication and increases the stiffness of the fibers (Ranalli, 2004). Plant Cell 31, 1344–1366.

Using a Genome-Wide Association Study. Int. (2011). Click here to go to our Indiegogo Campaign for a limited time - Holiday shopping. Plant cell walls throughout evolution: towards a molecular understanding of their design principles. Front. Front. The extensive phenotypic variation and the large genetic components of several cell wall traits (contents of glucose, mannose, xylose, glucuronic acid, Klason lignin, and acid detergent lignin) and bast fiber content make these traits excellent candidates to study the genetic architecture of fiber quality of hemp (Supplementary Tables 3, 4). Genet. In addition, their interactions between genotypes and environments (G × E) allow to study the heritable variation in fiber quality sensitive to the environment (Petit et al., 2020). Nonetheless, PCo1 and PCo2 only explained 23.18% of the total genetic variance (Figure 2A). Nat. Front. Each SNP was scored as the proportion of the major allele in the pool sample of plants from the same accession. View all High quality genomic DNA (2.5–5 μg at a concentration ≥ 25 ng/μl) was digested using the restriction enzyme EcoRI. Synthesis and turnover of cell-wall polysaccharides and starch in photosynthetic soybean suspension cultures. A panel of 123 hemp accessions was used in this study (Supplementary Table 1; Petit et al., 2020). It was observed that all clusters included significant markers from all the three trial locations. In the absence of a complete genome sequence it is difficult to map the boundaries of QTLs and to identify independent QTLs (Sawler et al., 2015). For a trait, a common QTL region can be composed of different genomic scaffolds, that harbor correlated (r ≥ 0.3; r2 ≥ 0.1) representative QTL-markers from MultiQTL models of two or three locations. Despite the large environmental component of glucuronic acid, as it phenotypic variation is also explained by the genetic factors, it is also a good candidate for genetic association studies.

Genome-wide efficient mixed-model analysis for association studies. Moreover, they are essential for plant development and responses to stress (Nguema-Ona et al., 2014; Strasser, 2014). These candidate genes were identified in six QTLs across locations, as detailed in Table 4. Current status and future scenarios of hemp breeding. Blast2GO: a universal tool for annotation, visualization and analysis in functional genomics research. The correlation study between marker frequencies also detected large correlations between markers that are far apart (distances up to ∼500 kbp and correlations up to r2 = 0.6). 5:363. doi: 10.3389/fpls.2014.00363, Struik, P. C., Amaducci, S., Bullard, M. J., Stutterheim, N. C., Venturi, G., and Cromack, H. T. H. (2000). The infection triggered the endogenous secretion of this enzyme in the cell wall, which degraded callose in plasmodesmata. Quality SNP marker selection was performed in R version 3.4.3 statistical software. Restriction site associated DNA sequencing generated 3,717.57 million clean reads (557.4 Gb) with an average of 29.7 million reads per sample (range 15.1–49.2 millions) with an average read length of 149.9 bp. Such studies would be very valuable for understanding the molecular mechanisms responsible for hemp fiber quality. For instance, the 12 significant markers from scaffold4465 were spread in a genomic sequence of ∼9,000 bp, while the 11 significant markers from scaffold34707 clustered in a shorter sequence of ∼600 bp.

APE: analyses of phylogenetics and evolution in R language. To further characterize the genetics of fiber quality traits across locations, a correlation analysis was performed between the QTLs of the three MultiQTL models for each trait, corresponding to the three test locations. The candidate genes identified in this study are of great significance for further studies, including reverse genetic approaches, such as candidate gene functional studies, but specially differential expression analysis from different stem tissues. (2014). Moreover, among the annotated transcripts were identified genes involved in plant defense mechanisms against pathogens, genes involved in redox reactions and genes involved in perception of light, such as phytochromes. Theor. The highly variable panel of 123 diploid hemp accessions (2n = 20) was used for this purpose (Petit et al., 2020). Arabidopsis mutant for one, two or three mns genes displayed lower amount of homogalacturonan-type pectin. These genes were involved in several plant physiological processes, including metabolism of proteins, lipids, carbohydrates (monosaccharides and polysaccharides), and lignin. Phytochem. Engineering flax and hemp for an alternative to cotton. (2011). Co-localization of scaffolds was also found in QTLXyl1 and QTLGlcA1 for respectively xylose and glucuronic acid content (Table 3). Our genotyping approach resulted in the detection of 2,852,901 SNPs with a missing rate < 50% in the population (number of samples with missing data divide by total number of samples). November 10, 2020. The study was performed on the 24 largest scaffolds (∼130–∼600 kbp) of the cannabis genome canSat3 version GCA_000230575.1 (van Bakel et al., 2011), that were covered with SNP markers.

All hemp fiber processing facilities are not created equal, and just because a facility is capable of decorticating hemp into fiber and hurd does not mean that it can achieve the quality standards necessary for more advanced products. All authors contributed to the article and approved the submitted version. RADseq data, selected informative SNP markers and the annotated transcriptomic data of the hemp cultivar C. sativa ‘Finola’ are deposited in the 4TU.ResearchData archive (https://doi.org/10.4121/12826832, https://doi.org/10.4121/uuid:d17c382c-f292-4875-888b-47e6433d600f). Using this approach, 16 QTLs were identified across locations for different fiber quality traits, including contents of glucose, glucuronic acid, mannose, xylose, lignin, and bast fiber content. Front. Color palette indicates the geographic origin of the accessions. Hemp yarn is smooth, consistent and very strong. (2016). Hempco est un fournisseur d’aliments, de fibres et de nutraceutiques à base de chanvre. The expected p-values were the significance level of the associations between genotypes and phenotypes under the assumptions that markers were unlinked to the polymorphism controlling the variation of the traits. Despite the large interest in hemp, it is a relatively poorly developed crop. Similar to textiles, hemp fibers can be used as blends with other pulp fibers such as wheat straw or flax or even recycled wood, in order to increase paper performance, strength and recyclability. (2011), Zhou and Stephens (2012), and Kruijer et al. Once cut, hemp fiber is usually left to be field retted — retting is a controlled process of decomposition that begins the separation of the bast and core fibers. The high heritabilities of these seven traits allow the study of the additive control of fiber quality traits. Plant Physiol. Plant Physiol. Plant Sci. This study provides new insights into the genetic architecture of fiber traits, identifies QTLs and candidate genes that form the basis for molecular breeding for high fiber quality hemp cultivars. The clean sequence reads of each sample were mapped to the C. sativa ‘Purple Kush’ (canSat3 version GCA_000230575.1) genome reference (van Bakel et al., 2011), using Burrows–Wheeler Alignment Tool (Li and Durbin, 2009; specific BWA parameters: (o) max number or fraction of gap opens = 1; (e) max number or fraction of gap extensions = 50; (m) maximum entries in the queue = 100,000). In miscanthus, the heritabilities of these traits ranged from 0.4 to 0.72 (Slavov et al., 2014; van der Weijde et al., 2017). Bast fibers can be cleaned, spun and then woven or knitted into many fabrics suitable for durable and comfortable clothing and housewares. A recent study in Arabidopsis described the product of cytochrome b5 as an obligate electron shuttle protein specific for the biosynthesis of syringyl lignin subunit (Gou et al., 2019). The identification of the boundaries of QTLs with a fragmented genome sequence in scaffolds is difficult. Moreover, these studies showed that the repression of c3h1 did not lead to deleterious impacts on plant growth. Besides, it can also be used for bio-remediation purposes of polluted lands (Struik et al., 2000; Amaducci et al., 2008; van den Broeck et al., 2008; Amaducci and Gusovius, 2010).

As a result, alterations in expression or function of glucan endo-1,3-β-glucosidase 3 gene is likely to affect the dynamism and architecture of the cell walls. Figure 1. Rev. Hemp seed varieties are grown for food and nutritional applications due to their high protein, fatty acid, and fiber content (i.e., a $15 bag of shelled hemp hearts from Whole Foods). Subsequently, a large set (> 600,000) of selected genome-wide single nucleotide polymorphism (SNP) markers was used for a genome-wide association study (GWAS) approach to get insights into quantitative trait loci (QTLs) controlling fiber quality traits. (2016). (2020) suggested that the content of this monosaccharide might have stronger general response to adapt to the environment, independently of the heritable genetic control of the trait. (2013) observed that the cell walls of the mutant plants were unaffected. The economics of using hemp fibers in many products are a subject of ongoing debate, research and development, and business analysis. doi: 10.1146/annurev.arplant.54.031902.134938, Camacho, C., Coulouris, G., Avagyan, V., Ma, N., Papadopoulos, J., Bealer, K., et al. The activity of this enzyme has been reported to play multiple roles, among them fiber elongation, carbon storage and energy production (Zieher, 2010). Its softness makes it both easy to work with and very comfortable when used for crafted jewelry that rubs against the skin. Cur. The biochemical composition of the cell walls from stems of the 123 accessions was measured with multivariate prediction models based on near-infrared spectroscopy (NIRS). Hemp is traditionally known as a fiber plant and most historical cultivation of the plant in the United States from the 17th to mid-20th centuries was with fiber use in mind. These two enzymes are essential in the biosynthesis of lignin and the suppression of their activity affects lignin content (Boerjan et al., 2003; Sykes et al., 2015). These enzymes function in a wide range of developmental processes, including cell separation and cell elongation to control the shape of the plant architecture (Gonzalez-Carranza et al., 2007; Babu and Bayer, 2014).
