Project description:Bermudagrass (Cynodon dactylon L.) is an important warm-season turfgrass species with well-developed stolons, which lay the foundation for fast propagation of bermudagrass plants through asexually clonal growth. However, the growth and development of bermudagrass stolons are still poorly understood at the molecular level. In this study, we comprehensively analyzed the succinylation modifications of proteins in fast growing stolons of bermudagrass cultivar Yangjiang. A total of 226 lysine succinylation sites on 128 proteins were successfully identified using liquid chromatography coupled to tandem mass spectrometry.

However, the growth and development of bermudagrass stolons are still poorly understood at the molecular level. In this study, we comprehensively analyzed the acetylation modifications of proteins in fast growing stolons of bermudagrass cultivar Yangjiang. A total of 4657 lysine acetylation sites on 1914 proteins were successfully identified using liquid chromatography coupled to tandem mass spectrometry.
Project description:Bermudagrass is an important warm-season turfgrass species with both erect growing shoots and prostrate growing stolons, however, the mechanism how bermudagrass shoots and stolons form and maintain their unique geotropic growth modes are still unclear. In this study, we compared the proteome of the internode section of shoots and stolons at the same developmental stage in bermudagrass cultivar Yangjiang. The results indicated that 376 protein species were differentially accumulated in the two types of stems.
Project description:To examine the role of formation of a strong sink during leaf senescence, we compared the expression profile of the flag leaf of three different sterile mutant lines with fertile plants. The fertile and sterile lines showed basically similar expression profiles of flag leaves sampled at the same time. However, the fertile lines showed more rapid and enhanced change in transcriptome as compared to the sterile lines indicating that leaf senescence initiated independent of sink formation and is accelerated by sink formation.
