Article Synopsis
- - The study aimed to identify genes related to fiber strength in cotton by analyzing three cultivars, including hyper-long, long, and short fiber types, using RNA-seq technology at different growth stages (20, 25, and 30 days post-anthesis).
- - A significant number of differentially expressed genes (DEGs) were found, with Sea Island cotton showing the highest number of DEGs compared to upland cotton cultivars, revealing crucial gene functionalities related to cellular processes and metabolic pathways involved in fiber development.
- - The researchers also conducted RT-qPCR to confirm the expression of nine specific DEGs that displayed notable differences across the fiber stages in the analyzed cotton cultivars, supporting their role in determining fiber strength
Article Synopsis
- Three specific carbon-chain extension genes involved in fatty acid synthesis play crucial roles in the oil accumulation of upland cotton seeds.
- The study reveals differences in the expression levels of these genes in high seed oil content cultivars compared to a low oil content cultivar throughout various seed development stages.
- Results indicate that these genes not only contribute to seed oil synthesis but also affect fiber elongation, highlighting their dual biological functions in cotton.
TBL (Trichome Birefringence Like) gene family members are involved in trichome initiation and xylan acetylation in several plant species. In our research, we identified 102 TBLs from G. hirsutum.

It is important to understand the genetic basis of seed germination for improving the vigor of crop seeds. However, little is known about the genetic basis of seed vigor in cotton.

View Article and Find Full Text PDFXinjiang has been the largest and highest yield cotton production region not only in China, but also in the world. Improvements in Upland cotton cultivars in Xinjiang have occurred via pedigree selection and/or crossing of elite alleles from the former Soviet Union and other cotton producing regions of China. But it is unclear how genomic constitutions from foundation parents have been selected and inherited.

Biological agent is an important green pathway to control Verticillium wilt. A field experiment was performed to examine the effects of Bacillus subtilis agent (15, 30 and 45 kg·hm), Trichoderma humatum agent (15, 18 and 24 kg·hm), 'Yufeng 99' agent (15, 22.5 and 30 kg·hm) and Zhongnonglyukang agent (30, 45 and 60 kg·hm) on cotton Verticillium wilt and soil microbial community.

In this study, Gossypium barbadense germplasm accessions with diverse origins (n = 123) were used to perform association analysis of fibre traits with 120 polymorphic simple sequence repeat (SSR) markers. In total, 120 polymorphic primer pairs amplified 258 loci with a mean of 2.
