水稻高产的基本前提是提高叶片光合效率，协调水稻植株的源库关系。来自日本的数量性状位点（qtl） qLSCHL4、粳稻NAL1等位基因具有多效性，能有效提高叶片叶绿素含量，增大旗叶大小，提高籼稻品种产量。水稻高产的基本前提是提高叶片光合效率，协调水稻植株源库关系。在籼稻93-11和粳稻“日本裸”构建的重组自交系中，在抽穗至成熟阶段检测到与水稻叶片形态性状和叶绿素含量相关的数量性状位点（QTL），并在两个阶段检测到与旗叶形状和叶绿素含量相关的主要QTL （qLSCHL4）。基于图谱的克隆和表达分析表明，LSCHL4与水稻窄叶突变体NAL1基因为等位基因。以Nipponbare LSCHL4和近等基因系93-11 （NIL-9311）为载体转化过表达系，叶片叶绿素含量显著增加，旗叶大小增大，穗型改善。NIL-9311的平均产量比93-11高出18.70%。这些结果表明LSCHL4具有多效性。探索和金字塔化更多类似LSCHL4的高产等位基因用于超级稻育种，为水稻增产取得新突破，为解决全球食品安全问题提供新思路提供了有效途径。
The basic premise of high yield in rice is to improve leaf photosynthetic efficiency, and coordinate the source–sink relationship in rice plants. The quantitative trait loci (QTLs) qLSCHL4, japonica NAL1 allele from Nipponbare has a pleiotropic function, effectively increased leaf chlorophyll content, enlarged flag leaf size, and enhanced the yield of indica rice cultivar. The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the source–sink relationship in rice plants. Quantitative trait loci (QTLs) related to morphological traits and chlorophyll content of rice leaves were detected at the stages of heading to maturity, and a major QTL (qLSCHL4) related to flag leaf shape and chlorophyll content was detected at both stages in recombinant inbred lines constructed using the indica rice cultivar 93-11 and the japonica rice cultivar Nipponbare. Map-based cloning and expression analysis showed that LSCHL4 is allelic to NAL1, a gene previously reported in narrow leaf mutant of rice. Overexpression lines transformed with vector carrying LSCHL4 from Nipponbare and a near-isogenic line of 93-11 (NIL-9311) had significantly increased leaf chlorophyll content, enlarged flag leaf size, and improved panicle type. The average yield of NIL-9311 was 18.70% higher than that of 93-11. These results indicate that LSCHL4 had a pleiotropic function. Exploring and pyramiding more high-yield alleles resembling LSCHL4 for super rice breeding provides an effective way to achieve new breakthroughs in raising rice yield and generate new ideas for solving the problem of global food safety.
