Mitogen-activated protein kinase (MAPK) cascades play pivotal roles in mediating biotic and abiotic stress responses. Cotton (Gossypium hirsutum) is the most important textile crop in the world, and often encounters abiotic stress during its growth seasons. In this study, a gene encoding a mitogen-activated protein kinase (MAPK) was isolated from cotton,(More)
Plant-specific NAC transcription factors comprise a large family with diverse roles in plant development and stress regulation. In this study, 73 NAC genes from cotton (Gossypium hirsutum) EST database were identified by bioinformatic approach. Analysis of conserved amino acid residues and phylogeny reconstruction using the NAC conserved domain suggested(More)
In this study, the GhKNL1 (KNOTTED1-LIKE) gene, encoding a classical class II KNOX protein was identified in cotton (Gossypium hirsutum). GhKNL1 was preferentially expressed in developing fibres at the stage of secondary cell wall (SCW) biosynthesis. GhKNL1 was localized in the cell nucleus, and could interact with GhOFP4, as well as AtOFP1, AtOFP4, and(More)
WRKY proteins that contain highly conserved WRKYGQK sequence and zinc-finger-like motif belong to a large transcription factor family in plants. In this study, 26 genes encoding putative WRKY proteins were identified in cotton (Gossypium hirsutum). On the basis of their conserved WRKY domain sequences, all of the GhWRKY proteins can be assigned to the(More)
In this study, the cDNA coding for a hybrid proline-rich protein (HyPRP) was isolated from cotton cDNA libraries and designated GhHyPRP3. Analysis of the deduced amino acid sequence revealed that it contained an N-terminal signal peptide, a central proline-rich domain, and a C-terminal cysteine-rich domain highly homologous to other hybrid proline-rich(More)
