“…Flax ( Linum usitatissimum L.) is a self-pollinating annual dicotyledonous crop, which can be divided into oil flax (Oil), fiber flax (Fiber) and oil-fiber dual purpose flax (OF) [ 13 ]. In contrast to the important crops of rice or wheat, flax is usually planted on barren land and even on saline alkali land in most of the flax countries, Canada, Russia and China, and the genetic diversity of the flax population under salt stress is still unclear [ 14 , 15 , 16 ]. Recently, a few studies were reported, all of which used transcriptome to study salt tolerance during the seedling stage of flax [ 17 , 18 , 19 ].…”

Soil salinization seriously affects the growth and distribution of flax. However, there is little information about the salt tolerance of flax. In this study, the salt tolerance of 200 diverse flax accessions during the germination stage was evaluated, and then the Genome-wide Association Study (GWAS) was carried out based on the relative germination rate (RGR), relative shoot length (RSL) and relative root length (RRL), whereby quantitative trait loci (QTLs) related to salt tolerance were identified. The results showed that oil flax had a better salt tolerance than fiber flax. A total of 902 single nucleotide polymorphisms (SNPs) were identified on 15 chromosomes. These SNPs were integrated into 64 QTLs, explaining 14.48 to 29.38% (R2) of the phenotypic variation. In addition, 268 candidate genes were screened by combining previous transcriptome data and homologous gene annotation. Among them, Lus10033213 is a single-point SNP repeat mapping gene, which encodes a Glutathione S-transferase (GST). This study is the first to use GWAS to excavate genes related to salt tolerance during the germination stage of flax. The results of this study provide important information for studying the genetic mechanism of salt tolerance of flax, and also provide the possibility to improve the salt tolerance of flax.

“…Jute is a natural bast fiber crop next to cotton in respect of commercial importance. It is an important industrial bio-fiber crop and its fiber can be used as a good source of biopolymer which is alternative to environment pollutant polythene [1] , [27] . It is one of the natural fibers producing diploid annual crops having diploid (

“…The saline stress can occur through (i) osmotic stress, caused by the decrease of soil water potential and subsequent reduced water absorption by roots [25]; (ii) nutritional stress, due to modification in nutrient uptake; (iii) toxic stress, mainly linked to salt concentration [26,27]; (iv) oxidative stress [28].…”

Plant-Based Protein Hydrolysate Improves Salinity Tolerance in Hemp: Agronomical and Physiological Aspects

Hemp (Cannabis sativa L.) is a multipurpose plant attracting increasing interest as a source for the production of natural fibers, paper, bio-building material and food. In this research we studied the agronomical performance of Cannabis sativa cv. Eletta Campana irrigated with saline water. Under those conditions, we tested the effect of protein hydrolysate (PH) biostimulant application in overcoming and/or balancing deleterious salinity effects. The results of the diverse treatments were also investigated at the physiological level, focusing on photosynthesis by means of a chlorophyll a fluorescence technique, which give an insight into the plant primary photochemical reactions. Four salinity levels of the irrigation solution (fresh water–EC0, and NaCl solutions at EC 2.0, 4.0 or 6.0 dS m−1, EC2, EC4 and EC6, respectively) were combined with 2 biostimulant treatments (untreated (control) or treated with a commercial legume-derived protein hydrolysate (LDPH)). The increasing salinity affected plant photochemistry resulting in lower plant growth and seed production, while the LDPH biostimulant showed a protective effect, which improved crop performance both in control and in salinity conditions. The LDPH treatment improved seeds yield (+38.6% on average of all treated plants respect to untreated plants), as well as residual biomass, relevant in fiber production.
