“…Similar to the plastid genome analysis, the phylogenetic analysis of mt genomes revealed Brassicales were closely related to Malvales in the rosids clades [1]. Sequencing and characterization of both nuclear and cytoplasmic genomes of the Gossypium species will enrich the knowledge used to identify fiber-related genes for the improvement of cotton fiber quality trait using modern genetic engineering tools [58,59].…”

Cotton (Gossypium spp.) produces naturally soft, single-celled trichomes as fiber on the seed coat supplying the main source of natural raw material for the textile industry. It is economically considered as one of the most leading cash crops in the world and evolutionarily very important as a model system for detailed scientific investigations. Cotton production is going through a big transition stage such as losing the market share in competition with the synthetic fibers, high popularity of Bt and herbicide resistance genes in cotton cultivars, and the recent shift of fiber demands to meet the standard fiber quality due to change of textile technologies to produce high superior quality of fibers in the global market. Recently, next-generation sequencing technologies through highthroughput sequencing at greatly reduced costs provided opportunities to sequence the diploid and tetraploid cotton genomes. With the availability of large volume of literatures on molecular mapping, new genomic resources, characterization of cotton genomes, discoveries of many novel genes, regulatory elements including small and microRNAs and new genetic tools such as gene silencing or gene editing technique for genome manipulation, this report attempted to provide the readers a comprehensive review on the recent advances of cotton fiber genomics research.

“…Upland cotton ( Gossypium hirsutum L.) is moderately salt-tolerant and can easily survive in the saline medium of 7.7 dS/m salt concentration [ 9 ] as compared to other important crops [ 10 , 11 ]. Moreover, a wide range of highly adaptable cotton cultivars are available, harboring tolerance against salinity.…”

Salinity is amongst the serious abiotic stresses cotton plants face, impairing crop productivity. Foliar application of β-alanine is employed to improve salt tolerance in various crops, but the exact mechanism behind it is not yet completely understood. An advanced line SDS-01 of upland cotton Gossypium hirsutum L. was utilized to determine its salt tolerance. Foliar treatment with the β-alanine solution at different concentrations was applied to the seedlings stressed with 0.8% NaCl solution. On the 10th day of treatment, samples were collected for transcriptome and metabolome analyses. β-alanine solution at a concentration of 25 mM was found to be the best treatment with the lowest mortality rate and highest plant height and above-ground biomass under salt stress. Both differentially expressed genes and accumulated metabolites analyses showed improved tolerance of treated seedlings. The photosynthetic efficiency improved in seedlings due to higher expression of photosynthesis-antenna proteins and activation of hormones signal transduction after treatment with β-alanine. Highly expressed transcription factors observed were MYB, HD-ZIP, ARF, MYC, EREB, DELLA, ABF, H2A, H4, WRKY, and HK involved in the positive regulation of salinity tolerance in β-alanine-treated seedlings. Furthermore, compared to the control, the high accumulation of polyamines, coumarins, organic acids, and phenolic compounds in the β-alanine-treated seedlings helped regulate cellular antioxidant (glutathione and L-Cysteine) production. Hence, to improve salt tolerance and productivity in cotton, foliar application of β-alanine at the seedling stage can be a valuable management practice.

Asiatic/Desi cotton (G. arboreum) is in demand in the North zone due to its higher price, tolerance to major sucking insects and better suitability under Cotton-Mustard Cropping system. The production of vigorous seeds in desi cotton is still a major challenge and, the present study was formulated to address this issue. An experiment with nine varieties in RBD was conducted for two years (2020-21 and 2021-22) to ascertain the influence of maturity duration and boll position on seed quality parameters in cotton. The tagged bolls for each genotype were harvested seperately from bottom (up-to 40 cm), middle (41–80 cm) and top position (more than 80 cm of plant height) at 140 days after sowing (DAS), 150 DAS, 160 DAS and 170 DAS respectively, and the seeds obtained after ginning were used for conducting experiments. Genotype, picking time, plant stratum and their interaction influenced the seed physiological parameters significantly. The highest mean germination (%) was observed in the seeds picked at 140 DAS (83.72%) followed by 150 DAS (83.14%) after which a significant decline in germination (%) was noticed. Significantly (P < 0.05) higher Seed vigour index-I (SV-I) & SV-II was noted in the seeds harvested during 140 DAS (2027.77 & 1435.44) to 150 DAS (2158.11 & 1254.21). A gradual decrease in terms of seed vigour parameters after 150 DAS suggested picking of matured bolls during 140 to 150 (DAS) for obtaining seeds with better quality in desi cotton.
