Project description:Saccharum spontaneum L., the main source of tolerance gene in sugarcane variety, is one of the most valuable germplasms for sugarcane breeding. In this study, 22 clones of S.spontaneum L. were selected from more than 690 collections in our preliminary experiment, and the cold tolerance of these clones were evaluated by physiological and biochemical indicators. Then 2 clones which were designated as lines 1027 and 3217,with contrasting cold tolerance ability were selected for further proteome analysis using DIA and PRM technology.
Project description:Tropical and subtropical plants are generally sensitive to cold and can show appreciable variation in their response to cold stress when exposed to low positive temperatures. Using nylon filter arrays, we analyzed the expression profile of 1536 expressed sequence tags (ESTs) of sugarcane (Saccharum sp.) exposed to cold for 3-48 h. Thirty-four cold-induced ESTs were identified, of which 23 were novel cold-responsive genes that had not previously been reported as being cold-inducible. This series has the samples from replicate experiment number 1. Keywords = sugarcane, cold, nylon arrays Keywords: time-course

Project description:Drought is considered the major abiotic stress limiting crop productivity. This study sought to identify proteins involved in the drought response in sugarcane stems submitted to drought stress. The integration of nuclei enrichment sample preparation with the shotgun proteomic approach (nLC-MS/MS) resulted in great coverage of the sugarcane stem proteome with 5,381 protein groups identified (1% FDR). A total of 1,204 differentially accumulated proteins (DAPs) were detected in response to drought, among which 586 showed increased abundance and 618 decreased abundance.
