The rice gene OsMYB55 can enhance the vegetative growth and improve grain yield of rice growth under high temperature conditions.
Contents
Annotated Information
Function
OsMYB55 is a transcription factor of R2R3-MYBs family members.OsMYB55 binds to the promoter regions of target genes and directly activates expression of some of several genes involved in amino acids metabolism including glutamine synthetase (OsGS1;2) glutamine amidotransferase(GAT1) and glutamate decarboxylase 3 (GAD3).The MYB plant transcription factor family members regulate numerous processes during the plant life cycle and are also involved in response to various environmental stresses [1].The MYB proteins are classified into three major groups based on the number of adjacent repeats in the binding domain; R1R2R3-MYB, R2R3-MYB, and R1-MYB. Most plant MYB proteins are of the R2R3 type.The R2R3-MYBs are involved in a wide range of physiological responses such as regulation of the isopropanoid and flavonoid pathways,control of the cell cycle, root growth,and various defense and stress responses [2].Molecular and biochemical analysis revealed that OsMYB55 enhances amino acid metabolic pathways crucial for normal plant growth and development under high temperature.
Expression
OsMYB55 is more Specifically Expressed at the Vegetative Stage.Expression analysis of the OsMYB55 revealed that transcript levels are higher at the vegetative stages up to tillering and the inflorescence stage. The transcription was higher in the root tissues compared to the leaves at these stages. However, its lowest expression level was observed in all seed development stages and at seed maturation.Expression analysis of the transgenic plants showed that OsMYB55 transcript levels were between fifty and ninety times higher in the transgenic lines than in the wild type plants
