光敏色素B介导光信号影响水稻的脱落酸途径

研究表明,拟南芥中光敏色素介导的光信号与植物激素脱落酸(abscisic acid,ABA)途径相互作用.但水稻光敏色素与ABA途径之间是否相互影响仍不清楚.利用野生型和phyB突变体水稻作为研究材料,分析phyB介导的光信号对ABA生物代谢和ABA反应的影响.结果表明,ABA合成代谢相关基因OsNCED1,OsNCED2,OsNCED3和OsNCED4在phyB突变体中的表达水平明显高于野生型,而ABA降解代谢基因OsABAOX1则相反,这可能解释了phyB突变体积累较多内源ABA的原因.外源ABA处理明显抑制黑暗和光照下生长的水稻种子的萌发,但光照条件下ABA对phyB突变体种子萌发的抑制效果更明显.据此推测,phyB感受的光信号消弱了ABA对种子萌发的抑制效果.通过分析部分已报道的种子萌发相关基因在正常或ABA处理的野生型和phyB突变体中的表达水平,结果表明,phyB介导的光信号对水稻种子萌发的调控作用可能与这些基因无关.此外,在红光条件下,ABA处理能够抑制水稻幼苗地上部分的生长,野生型和phyB突变体对ABA处理的反应基本相同;但是ABA对phyB突变体主根生长的抑制效果显著高于野生型,这个结果表明phyB介导的光信号不影响ABA对水稻幼苗地上部分生长的抑制效果,但负调控ABA对主根生长的抑制效果.上述研究结果表明,phyB介导的光信号负调控水稻ABA的积累和ABA反应.本研究揭示了水稻光敏色素对ABA途径的影响,为深入研究光信号途径和ABA途径之间协同调控水稻发育的分子机制奠定了基础.

云南陆稻品种籼粳分化与遗传变异

利用34个籼粳特异插入缺失(insertion/deletion,InDel)分子标记和24个SSR分子标记对云南113个陆稻品种的籼粳分化与遗传变异进行分析.InDel分子标记鉴定结果表明,云南陆稻以粳稻(粳型、偏粳型)品种为主,占总品种的83.2%.聚类结果显示,云南陆稻品种明显聚为4大类群(籼型、偏籼型、粳型、偏粳型),支持InDel分子标记鉴定结果.重新将云南陆稻品种的种植区域划分为2个:(1)海拔1250m以下为籼粳稻混合种植区;(2)海拔1250m以上为粳稻种植区.SSR遗传多样性分析结果表明,云南陆稻籼粳亚种间遗传多样性均很丰富,籼稻品种的遗传多样性高于粳稻品种且差异显著.分子方差分析显示,云南陆稻遗传变异主要来自亚种内(占总变异81%),亚种间遗传变异占19%.不同地区间陆稻种质资源遗传多样性比较分析表明,滇西南与滇南地区存在丰富的遗传变异,是云南陆稻品种遗传多样性的分布中心.半山云雾多湿区作为云南陆稻品种的传统种植区域,保留大量的遗传变异与稻种资源,是开展陆稻种质资源保护、利用的核心区域.
