| Popis: | Tubby-like protein genes (TULPs), present in the form of large multigene families, play important roles in environmental stress. However, little is known regarding the TULP family genes in cotton. In this study, we systematically identified and analyzed the membership, characterization, and evolutionary relationship of TULPs in four species of cotton. Transcriptome analysis indicated that GhTULPs participate in environmental stress and cotton tissue development. At the same time, we also predicted and analyzed the potential molecular regulatory mechanisms and functions of TULPs. GhTULP34, as a candidate gene, significantly reduced the germination rate of transgenic Arabidopsis plants under salt stress, and inhibited root development and stomatal closure under mannitol stress. The yeast two-hybrid and luciferase (LUC) systems showed that GhTULP34 can interact with GhSKP1A, a subunit of the SCF-type (Skp1-Cullin-1-F-box) complex. This study will provide a basis and reference for future research on their roles in stress tolerance. |
