水稻中已克隆出十几个控制类病变(lesion mimic, LM)性状的基因，其中以SPL (spotted leaf)命名的基因如OsSPL7、OsSPL11、OsSPL28分别编码不同功能的蛋白质。本研究首先分析OsSPL7、OsSPL11和OsSPL28启动子序列，发现均含有大量应答激素和逆境的顺式作用元件，并采用实时定量PCR检测这3个Os SPL基因在水稻不同部位的表达情况，以及逆境和激素等不同处理对它们在转录水平表达的影响。结果表明：OsSPL7、OsSPL11和OsSPL28在不同时期水稻组织中没有明显的时空差异表达；低温、盐、干旱胁迫和ABA、ACC、JA、SA四种激素在转录水平调控OsSPL7、OsSPL11和OsSPL28表达，其中OsSPL7表达受低温、干旱、ACC和JA抑制而受ABA、SA诱导，Os SPL 11表达受低温、干旱和JA抑制而受SA显著诱导，Os SPL 28表达受到JA强烈抑制而对低温不敏感。研究结果可为进一步研究激素和非生物胁迫调控植物类病变发生的作用机制提供线索。“,”A few candidate lesion mimic mutant (LMM) genes had been isolated from rice. Among them, OsSP-L7, OsSPL11 and OsSPL28 encode different functional proteins, respectively. There are multiple cis-acting elements in promoter sequences of these three LMM genes in response to various stresses and hormone signaling. The expression patterns analyses using real time PCR showed that these LMM genes had no tissue specialty in expression. However, they exhibited different expression characterizations under low temperature, salt, drought, ABA, ACC, JA and SA treatments. For examples, the expression of OsSPL7 was suppressed by cold, drought , ACC and JA and induced by ABA and SA;the transcripts of OsSPL11 was inhibited by low temperature, drought and JA and enhanced significantly by SA;while the expression of OsSPL28 was strongly suppressed by JA and insensitive to low temperature. These results could provide clues for further investigating the functional mechanism of lesion mimic under hormone and abiotic stress.
