1Manipulation of SlMXl for enhanced carotenoids accumulation and drought resistance in tomato显示文摘Plants are the ultimate source of nutrients in the human diet. To ensure adequate availability of high quality food for an increasing world population, traits including improved tolerance of stresses and nutrient levels need to be selected in crops, both individually and in combination. Here we report the identification of Sl MX1 encoding a MIXTA-like MYB transcription factor in tomato that simultaneously modulates drought resistance and metabolic processes through regulating key structural and regulatory genes of the corresponding pathways. Over-expression of Sl MX1 results in substantially increased drought tolerance and improved fruit quality, while knocking down Sl MX1 resulted in the opposite phenotypes. Our study indicates an effective way with multiple beneficial traits by genetic engineering of a single regulatory gene and can be a novel approach to breeding crops.Mohamed Ewas Yanqiang Gao Shouchuang Wang Xianqing Liu Hongyan Zhang Elsayed M.

2RNA-seq reveals mechanisms of SlMX1 for enhanced carotenoids and terpenoids accumulation along with stress resistance in tomato显示文摘Improving nutritional fruit quality and impacts important agro-traits such as biotic or abiotic stresses are extremely important for human civilization.Our previous study reported that manipulation of Sl MX1 gene enhanced carotenoids accumulation and drought resistance in tomato.Here,RNA-Seq analysis proved to be a very useful tool to provide insights into the regulatory mechanisms of Sl MX1 involved in stress resistance and enhanced secondary metabolites.Physiological analysis showed that overexpression of Sl MX1 results in substantially increased broad-spectrum tolerance to a wide-range of abiotic and biotic(fungus,bacteria,virus and insects) stresses in tomato.This research appears to be of remarkable interest because enhanced terpenoids content has been achieved by increasing trichome density.In addition,we reported two types of trichome which seems to be aberrant types in tomato.This study unravels the mechanism of regulation of Sl MX1,which simultaneously modulates resistance and metabolic processes through regulating key structural and regulatory genes of the corresponding pathways.Mohamed Ewas Yangqiang Gao Farhan Ali Elsayed M.
