Comparative Dynamic Transcriptome Reveals the Delayed Secondary-Cell-Wall Thickening Results in Altered Lint Percentage and Fiber Elongation in a Chromosomal Segment Substitution Line of Cotton (Gossypium hirsutum L.)

Abstract: Lint percentage (LP) is an important yield component in cotton that is usually affected by initial fiber number and cell wall thickness. To explore how fiber cell wall development affects LP, phenotypic identification and dynamic transcriptome analysis were conducted using a single segment substitution line of chromosome 15 (SL15) that harbors a major quantitative trait locus (QTL) for LP. Compared to its recurrent parent LMY22, SL15 did not differ in initial fiber number, but the fiber cell wall thickness and… Show more

“…Chinese researchers traveled to Mexico, the United States, France, Australia, and other countries to explore and collect cotton germplasm resources from the 1970s to 1980s, with more than 4800 cultivars, lines, wild species, semi-wild species, and special lines with genetic markers collected by 1984 ( Gao et al, 2021 ). A total of 8868 accessions were collected and preserved by 2020, including 7362 G. hirsutum , 350 G. hirsutum wild races, 633 G. barbadence , 433 G. arbareum , 18 G. herbaceous , and 32 wild species, making the cotton collection in China the fourth largest in the world ( Du et al, 2012 ).…”

“…Cotton fiber quality is based on several properties, such as fiber fineness, length, strength, micronaire ( i.e ., cell wall thickness), and yellowness ( Bajwa et al, 2015 ; Song et al, 2021 ; Yang et al, 2022 ). Increased demand for luxury textiles has likewise increased the demand for high-quality cotton fiber; consequently, there is also increased interest in improving fiber quality in the more highly productive species/cultivars ( Gao et al, 2021 ; Huang et al, 2021a ). While breeding programs are attempting to introgress desirable fiber quality traits into these productive lines, like most crops, cotton fiber yield and quality traits are quantitatively controlled by multiple genes, limiting the success of traditional breeding techniques ( Liu et al, 2023 ; Xu et al, 2019 ).…”
