盐胁迫对不同水稻品种光合特性及基因表达的影响
Effects of salt stress on photosynthetic characteristics and gene expression of different rice cultivars
摘要
Abstract
Soil salinization has serious effects on the growth and development of rice.It is important to investigate the effects of salt stress on photosynthesis and gene expression of different rice cultivacs for high and stable production of rice.The present study determined the photosynthetic characteristics of rice under the stress condition of 125 mmol/L NaCl for 6 d.The experimental mate-rials were'yijing12'and'xindao36'.The results showed that the decrease in maximum fluorescence yield(Fm)、primary light en-ergy conversion efficiency(Fv/Fm)、net photosynthetic rate(Pn)、stomatal conductance(Gs)、intercellular CO2 concentration(Ci)、transpiration rate(Tr)and the relative content of chlorophyll(SPAD)of'yijing12'were greater than those of'xindao36'un-der stress condition of 125 mmol/L NaCl.The qRT-PCR analysis revealed that both OsABCI7 and OsHCF 222 genes were signifi-cantly up-regulated in gene expression within a short period of time.The subcellular localization analysis exhibited that the protein encoded by OsABCI 7 gene was localized in chloroplasts,and the protein encoded by OsHCF 222 gene was localized in cytoplasm.Taken together,the defense ability of the photosynthetic system with the'yijing12'was superior to that of'xindao36',which will further provide a theoretical basis for the screening and identification of salt-tolerant rice resources.关键词
