ABA and JA crosstalk regulates seedling salt tolerance in rice varieties with different salinity tolerances

TO INVESTIGATE THE MECHANISMS UNDERLYING RICE SEEDLINGS' RESPONSE TO SALT STRESS, TRANSCRIPTOME ANALYSIS WAS CONDUCTED TO EXAMINE GENE EXPRESSION CHANGES IN SALT-TOLERANT AND SALT-SENSITIVE RICE VARIETIES. IN THIS STUDY, THE SALT-TOLERANT LANDRACE RICE FAGUODAO AND THE SALT-SENSITIVE CULTIVAR RICE NIPPONBARE WERE USED. BOTH WERE SUBJECTED TO 125 MMOL/L NACL TREATMENT AT THE SEEDLING STAGE, AND TRANSCRIPTOME SEQUENCING WAS EMPLOYED TO ANALYZE STRESS-RESPONSIVE GENES AND REGULATORY NETWORKS.

为解析水稻幼苗响应盐胁迫的分子机制，本研究通过转录组（transcriptome）分析，探究耐盐与盐敏感水稻品种的基因表达变化。本研究选用耐盐地方品种稻谷岛（FAGUODAO）与盐敏感栽培品种日本晴（NIPPONBARE）作为实验材料。二者均在幼苗期接受125 mmol/L氯化钠（NaCl）胁迫处理，并通过转录组测序技术，分析水稻的胁迫响应基因及其调控网络。
