[目的]为解析小麦(Triticum aestivum L.)白叶突变体叶色白化机制,以白叶突变小麦体和正常小麦为试验材料,从转录水平方向展开研究。[方法]以正常小麦和温敏白叶突变体小麦为材料,进行叶色变化过程的比较转录组学分析,挖掘调控小麦光合色素形成的调控机制。[结果]参与正常小麦叶片发育过程的DGEs数目是白叶小麦叶色由白转绿过程的2.57倍,且正常叶片发育过程的DGEs主要参与脂类、氨基酸、蛋白质、嘌呤、肌醇等生物大分子的代谢,而叶色由白转绿过程的DGEs主要参与光合作用、呼吸作用和糖代谢等过程;同时发现,小麦拥有已知植物光合色素代谢途径中的所有基因,其中的75个基因为DGEs,这些DGEs包含了所有叶绿素合成途径的基因和2个类胡萝卜素合成途径的基因,这些基因的表达模式分为7类(Ⅰ-Ⅶ),表达模式表明小麦叶绿素的生物合成受反馈调节,并且叶绿素合成受阻导致试验材料形成白叶,TaCAO可能是叶绿素合成受阻的主要影响因子。[结论]该研究为进一步研究小麦叶绿素形成机制奠定了基础。 展开更多

用自然产生的粳稻白叶突变体6108及其衍生品系和绿叶品种杂交,F1均表现为绿色,说明白叶突变性状为核隐性遗传。F2,BF1中出现绿叶和白叶的分离,10个组合F2代绿叶植株与白叶植株的分离符合3∶1的分离比。3个组合BF1的分离符合1∶1的分离比... 用自然产生的粳稻白叶突变体6108及其衍生品系和绿叶品种杂交,F1均表现为绿色,说明白叶突变性状为核隐性遗传。F2,BF1中出现绿叶和白叶的分离,10个组合F2代绿叶植株与白叶植株的分离符合3∶1的分离比。3个组合BF1的分离符合1∶1的分离比,说明粳稻6108白叶突变体受一对隐性基因控制。对该白叶突变体的农艺性状观察表明,白叶性状对营养生长的负面影响主要表现在前期,随生育进程影响逐渐减少,对产量影响较小。 展开更多

[Objective] The aim was to screen the foliar fertilizer and growth regulators to improve the quality of Jinhua Large and White Peach. [Method] The effects of seven foliar fertilizer and growth regulators on the major economic traits of Jinhua Large and White Peach were studied. [Result] After timely spraying of S-ABA and Fushizhuang in young fruit stage,the major economic traits of Large and White Peach including fruit weight and soluble solids content were significantly higher than that of the control,and significantly better than other treatments. In addition,Huoqing spraying treatment could obviously improve the quality of Large and White Peach. [Conclusion] Shifuzhuang,S-ABA and Huoqing spraying could significantly improve the quality of Jinhua Large and White Peach,which were suitable to be disseminated and applied in production. 展开更多

Comparative studies of the biochemical parameters of the leaves and seeds of Moringa oleifera was carried out to provide additional information on the nutritional status of the leaf and seed of M, oleifera. The vegetative and floral characters of the plants collected were examined, floral diagram and formular were recorded. Protein variation in the dry seed and leaf is an indication of protein polymorphism and this depicts the genetic divergence in the leaf and seed ofM. oleifera. Protein bands at 0.4, 1.1, 3.9 and 5.8 are taxonomically distinct, thus diagnostically separated the dry seed from other samples. Proximate analysis shows that the dry samples are more nutritious than the wet samples. 展开更多
