additional information	transgenic overexpression of SlUPB1 in tomato, upregulation of gene SlUPB1 in heat-sensitive variant L4783 and downregulation of gene SlUPB1 in heat-tolerant variant CL5915. Pollen germination rates of transgenics overexpressing SlUPB1 are higher than germination rates of the background tomato L4783. Germination rates of transgenics downregulating SlUPB1 are significantly lower than germination rates of background tomato CL5915	Solanum lycopersicum

stamen	in the anthesis stage, gene SlUPB1 expression in heat-tolerant tomato variant CL5915 stamens, growing at 35/30°C (day/night), is 2.16 and 2.93times greater than that in a heat-sensitive tomato variant L4783 cultivated at 30/25°C or 25/20°C, respectively	Solanum lycopersicum	-

General Information

General Information	Comment	Organism
physiological function	expression of a gene encoding beta-ureidopropionase is critical for pollen germination in tomatoes. beta-Alanine effectively enhances pollen germination in tomatoes with low SlUPB1 expression. beta-Alanine may play a role in pollen germination under both optimal and high temperatures	Solanum lycopersicum
