Cotton is an important fiber crop worldwide. Improved fiber quality is a driving force for cotton genetic studies and breeding. A BC1 population containing 115 individuals from a cross between Gossypium hirsutum cv. CCRI8 and G. barbadense cv. Pima 90-53 was established, and 519 simple sequence repeat (SSR) markers, two conserved intron-scanning primers(More)
OBJECTIVE To investigate LC3B-II and active caspase-3 expression in human colorectal cancer to elucidate the role of autophagy, and to explore the relationship of autophagy with apoptosis in human colorectal cancer. METHODS LC3B expression was detected by immunohistochemistry in 53 human colorectal cancer tissues and 20 normal colon tissues. The protein(More)
The function of a member of the actin-depolymerizing factor family from Gossypium barbadense, GbADF1, was investigated. Tobacco (Nicotiana tabacum) lines expressing GbADF1 were produced by Agrobacterium-mediated transformation. Southern and northern blot analyses showed that GbADF1 was successfully incorporated as a single copy into the tobacco genome and(More)
Overexpression of GhACL5 , an ACAULIS5 from cotton, in Arabidopsis increased plant height and T-Spm level. Silencing of GhACL5 in cotton exhibited a dwarf phenotype and reduced resistance to Verticillium dahliae. The Arabidopsis thaliana gene ACAULIS5 (ACL5), for which inactivation causes a defect in stem elongation, encodes thermospermine (T-Spm) synthase.(More)
Fasciclin-like arabinogalactan (FLA) protein is a cell-wall-associated protein playing crucial roles in regulating plant growth and development, and it was characterized in different plants including Upland cotton (Gossypium hirsutum L.). In cDNA-AFLP analysis of 25 DPA (days post anthesis) fiber mRNA, two FLA gene-related transcripts exhibit differential(More)
Uridine diphosphate-glucose dehydrogenase (UGD, EC1.1.1.22 oxidizes UDP-Glc (UDP-D-glucose) to UDP-GlcA (UDP-Dglucuronate), a critical precursor of cell wall polysaccharides. GbUGD6 from Gossypium barbadense is more highly expressed late in the elongation of cotton fibers (15 d post-anthesis (DPA)) and during the stage of secondary cell wall thickening (30(More)
Fiber strength is an essential trait of fiber property in cotton, and it is quantitatively inherited. Identification of stable quantitative trait loci (QTL) contributing to fiber strength would provide the key basis for marker-assisted selection (MAS) in cotton breeding. In this study, four interspecific hybridization populations were established with a(More)
Cotton S-adenosylmethionine decarboxylase-, rather than spermine synthase-, mediated spermine biosynthesis is required for salicylic acid- and leucine-correlated signaling in the defense response to Verticillium dahliae. Spermine (Spm) signaling is correlated with plant resistance to the fungal pathogen Verticillium dahliae. We identified genes for key(More)
Expression of DHS1 in cotton is induced upon infection by Verticillium dahliae , and overexpression of GhDHS1 endows transgenic Arabidopsis plants excellent Verticillium resistance. Verticillium wilt is caused by a soil-borne fungus Verticillium dahliae. Resistance in most cotton cultivars is either scarce or unavailable, making Verticillium wilt a major(More)
