hemp fiber quality

M-JP and EL helped analyzing the data and revised the manuscript. Table 3. Hemp Farmers. (2015). Well-crafted hemp textiles are durable, breathability and have strong thermal qualities, as well as being mildew-resistant and hypoallergenic. In addition, cytochrome b5 was also identified in QTLKL1 for lignin content. These high heritabilities indicate that the genetic gains of fiber quality can be maximized in several crops. (2013). *Correspondence: Luisa M. Trindade,, Front. Sci. Doyle, J. J., and Doyle, J. The hemp fiber market in the U.S. is still developing, but worldwide, the top commercial/industrial uses for hemp fiber are : (1) textiles/clothes, (2) as building materials (most frequently as insulation), (3) material for shoes, (4) paper, and (5) ropes and cords. 122, 1605–1616. In Arabidopsis, three α-mannosidase genes have been identified, named as mns genes. Therefore, genes involved in cell wall associated defense can modify cell wall composition [reviewed in Underwood (2012)]. Two clusters of markers were identified for respectively contents of glucose, xylose, lignin (ADL, KL), and bast fiber content, while only a single cluster of markers was identified for respectively contents of mannose and glucuronic acid. Moreover, these studies showed that the repression of c3h1 did not lead to deleterious impacts on plant growth. Briefly, low lignin content in the bast fibers is associated to high quality of fiber for textile purposes. doi: 10.1016/j.indcrop.2014.08.011, Sarkar, P., Bosneaga, E., and Auer, M. (2009). Each plot is shown in the angle that represents better the results. Theor. This method enables genome-wide association analyses for hemp, and it can be extended to genetic studies in other orphan species, for which no complete and assembled genome is available (Graham, 2013). Mol. The N-glycans are oligosaccharides (Glc3Man9GlcNAc2) linked to nitrogen (N) and involved in the biosynthesis of N-glycoprotein (Liebminger et al., 2009). The accumulation of malate and sugars, is thought to play an important role in the fiber elongation, through osmotic regulation and charge balance. Chicago, IL: University of Chicago Press. These genes are known to be regulated at the level of transcription. Historically, hemp may be one of the earliest, if not the first sustainable industrial performance driven fibrous raw material used in the production of textile products. Weed Biol. Cytochrome b5 is an obligate electron shuttle protein for syringyl lignin biosynthesis in Arabidopsis. To harvest the hemp, the plants are cut 2-3cm above the soil and then dried for a few days. APE: analyses of phylogenetics and evolution in R language. Biofuels 8:128. doi: 10.1186/s13068-015-0316-x, Torres, A. F., Noordam-Boot, C. M. M., Dolstra, O., Van Der Weijde, T., Combes, E., Dufour, P., et al. Plant Genomics 2008:619832. doi: 10.1155/2008/619832, Conesa, A., Gotz, S., Garcia-Gomez, J. M., Terol, J., Talon, M., and Robles, M. (2005). Received: 27 May 2020; Accepted: 25 August 2020;Published: 17 September 2020. This “cottonized” fiber will especially be well suited for textile applications. The transcriptome of the hemp cultivar C. sativa ‘Finola’ (finola1), aligned to the C. sativa ‘Purple Kush’ (canSat3 version GAC 000230575.1) assembly, was downloaded from the C. sativa Genome Browser Gateway at (van Bakel et al., 2011). Euphytica 209, 357–376. A Linear Mixed Model (LMM) was used to identify significant associations between SNP markers and fiber quality traits, using a kinship correction (VanRaden, 2008) and following the same approach as in Yu et al. LMM analyses were performed using restricted maximum likelihood (REML) algorithm and the kinship was calculated using R1 version 3.4.3 statistical software. Cur. In order to gain a better understanding of how these factors impact on hemp fibers, commercial hemp varieties were grown under different agricultural conditions and analyzed for fiber content, cell size and cell wall composition. In this report, sixteen QTLs across locations were found to be associated to fiber quality in hemp. 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). Downregulation of gapdh in Arabidopsis resulted in drastic changes in the sugar balance of the plant, arrested root development and dwarfism (Muñoz-Bertomeu et al., 2009). Hemp fiber has been used since ancient times to make textiles. 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. (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. These candidate genes were suggested to play an important role in determining fiber quality in hemp. Stilbene synthase is another gene involved in the flavonoid and stilbene biosynthesis. doi: 10.1101/458083, He, N., Zhang, C., Qi, X., Zhao, S., Tao, Y., Yang, G., et al. Flax and Hemp solutions meet not only the technical requirements of composite manufacturers in terms of innovative and high-performance reinforcements, but also societal expectations in terms of fiber traceability. The contents of bast fiber, cellulose and lignin were reported to be largely determined by genetic components in the hemp accession panel from Petit et al. (2020). doi: 10.1104/pp.109.143701, Nguema-Ona, E., Vicré-Gibouin, M., Gotté, M., Plancot, B., Lerouge, P., Bardor, M., et al. A polygalacturonase gene, with reported activity in pectin hydrolysis, and 2-phytyl-1,4-β-naphthoquinone methyltransferase, with reported activity in flavonoid biosynthesis, were identified in QTLADL1 for ADL content. Also, male and female plants differ in stature and produce fibers with different properties and quality. (2008). The Theory of Gene Frequencies. Genome-wide association studies and prediction of 17 traits related to phenology, biomass and cell wall composition in the energy grass Miscanthus sinensis. Bioinformatics 21, 3674–3676. The capital investment to purchase the Hemp Fiber Classifier is a fraction of the cost of traditional decorticators while providing substantially better end products. Physiol. 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). The largest hemp fiber processing machines are capable of separating every component of the hemp plant (including the flower), rendering clean, high-quality raw material that is ready for manufacturers across countless industries. Rapid SNP discovery and genetic mapping using sequenced RAD markers. Along with bamboo, hemp is one of the fastest growing plants on Earth. Subsequently, SOAPsnp was used to call SNPs in each sample (Li et al., 2009). For instance, the gene cytochrome b5, identified in the genomic scaffold common for glucose and lignin content, can directly affect lignin content. The large variability of the hemp panel enables further mapping studies for hemp traits that still remain poorly studied. Two genes involved in sugar metabolism (glyceraldehyde-3-phosphate dehydrogenase (gapdh) and α-mannosidase) and two genes indirectly involved in the lignin metabolism, [chalcone synthase (chs) and stilbene synthase (sts)], primarily involved in the precursor pathways of flavonoid and stilbene biosynthesis, were identified in QTLGlcA3 for glucuronic acid content. J. Front. Male plants die after shedding pollen, but fiber crops are usually harvested before or during flowering. Some people prefer hemp rope’s coarser texture as the rope can bind against itself for better knot stability. (2010). The study of the genetic architecture of hemp fiber quality is fundamental to develop molecular strategies to breed for new hemp cultivars with improved fiber properties. Impact Factor 3.258 | CiteScore 2.7More on impact ›, Applied Genetics of Natural Fiber Plants The fabric obtained from hemp are good for sensitive people too and don’t cause allergies. |,,,,, Creative Commons Attribution License (CC BY). Therefore, r2 ≥ 0.1 was used as threshold for collinearity of markers in the multiQTL models (see section “Genome-Wide Association Study (GWAS) Analysis”). Chem. It was also one of the first plants to be spun into usable fiber 50,000 years ago. The supernatant was then treated with RNAseA (100 μg RNAseA per 700 μl supernatant, 30 min at 37°C) and extracted with chloroform: isoamyl alcohol (IAA). We grow our own hemp to ensure quality, yield, and full control over our supply. Down-regulation of p-coumaroyl quinate/shikimate 3’-hydroxylase (C3’H) and cinnamate 4-hydroxylase (C4H) genes in the lignin biosynthetic pathway of Eucalyptus urophylla x E. grandis leads to improved sugar release. A methyltransferase gene involved in the biosynthesis of many cell wall components was identified in QTLKL2 and a glucan endo-1,3-beta-glucosidase 3 gene was identified in QTLKL3. (2013). 5, 1009–1019. Int. 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. (2015), was used to calculate the kinship matrix by using the entire set of selected markers. Front. Allelic variation of c3h1 can directly lead to phenotypic variation of lignin content, as reported in other crops (Ralph et al., 2006, 2012; Sykes et al., 2015). Generally, fiber hemp is harvested 70-90 days after seeding. These advances in hemp processing allow for a cleaner separation of fibers without the bother of field retting, making for a stronger and superior bast fiber. The complex interactions between flowering behavior and fiber quality in hemp. X-axes = principal component 1 (PC1) with the percentage of explained variance; Y-axes = principal component 2 (PC2) with the percentage of explained variance; Z-axes = significant levels of the loci in the genome-wide association study (GWAS) association (-log10P); Orange, green, and purple dots = significant QTL-markers detected in respectively Centro di ricerca cerealicoltura e colture industriale (CRA), Fédération Nationale des Producteurs de Chanvre (FNPC), and Vandinter Semo BV (VDS); Orange, green, and purple dots with a black circle = representative QTL-markers of the MultiQTL models from respectively CRA, FNPC, and VDS; CRA = field trial in Italy; FNPC = field trial in France; VDS = field trial in Netherlands; QTL-names (e.g., s55006_23495) = QTL-markers from different MultiQTLs models; QTL-names in bold and underlined (e.g., s69515_8050) = QTL-markers from different MultiQTLs models that belong to a QTL region across locations. PLoS One 3:e3376. Variation in 2-phytyl-1,4-β-naphthoquinone methyltransferase might affect the lignin content similarly to chalcone and stilbene genes. Lignin and xylans are cross-linked (Pauly et al., 2013) and highly correlated (Petit et al., 2020). HiLo offers a growing list of hemp seed for sale, ranging from high CBD, low THC feminized hemp seed to fiber and grain. Effects of coumarate 3-hydroxylase down-regulation on lignin structure.
