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 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.

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.
Project description:As a widely used turfgrass species, bermudagrass (Cynodon dactylon L.) can be easily propagated by colonial growth of stolons. Previous studies collectively revealed that exotic environmental factors and intrinsic hormones and genes are all involved in the differentiation, development, and diageotropically growth of stolons. However, the detailed molecular mechanism how environmental and hormone signals regulate the gene expression and biochemical activities in bermudagrass stolons remains unclear. In this study, LC-MS/MS analyses of the total protein extracts of bermudagrass stolons without preliminary phosphopeptide-enrichment successfully identified 862 nonredundant phosphorylation sites and 613 phosphoproteins.
Project description:As an important perennial warm-season turfgrass species, bermudagrass (Cynodon dactylon L.) form underground-growing rhizomes and aboveground-growing stolons simultaneously, making it a fast propagating clonal plant with strong regeneration ability. However, the intrinsic difference between the two types of specialized stems are still uncharacterized, especially at the molecular level. In the current study, we compared the internode proteomes of rhizomes and stolons at the same developmental stage in the bermudagrass cultivar Yangjiang using isobaric tags for relative and absolute quantitation (iTRAQ). The results indicated that 228 protein species were differentially accumulated in the two specialized stems. These DAPs comprise complex protein networks to finely regulate diverse cellular activities in the two types of specialized stems. Notably, photosynthesis and flavonoid biosynthesis were significantly regulated in stolons, whereas sucrose and starch metabolism were significantly regulated in rhizomes.
