Herba epimedii(Epimedium),a traditional Chinese medicine,has been widely used as a kidney tonic and antirheumatic medicine for thousands of years.In Epimedium,flavonoids have been demonstrated to be the main bioactive components(BCs).However,the molecular biosynthetic and regulatory mechanisms of flavonoid-derived BCs are still obscure.

葛枣猕猴桃叶片结构特征及光谱学特性研究

葛枣猕猴桃叶片颜色在生长期内呈现白、绿相间，本研究通过观测其叶片结构特征和光谱学特性，以期阐明葛枣猕猴桃彩叶呈色原因。结果显示：葛枣猕猴桃白色叶片较绿色叶片其栅栏组织细胞分散排列，可见大量气室，而正常绿色叶片栅栏组织细胞呈圆柱形紧密排列。反射光谱数据显示，白叶近轴面反射在485-1000 nm区间均高于绿色叶片，但当叶片返绿后，其反射谱类似于绿叶。在远轴表面，白色叶片在450-750 nm区间与绿

橡胶树海藻糖-6-磷酸合成酶基因参与乳管蔗糖代谢与产胶调控

海藻糖-6-磷酸合成酶(TPS)在植物蔗糖代谢和生长发育中发挥重要作用。但迄今为止,对其相关的调控机制知之甚少,已有认识主要基于对模式植物拟南芥的研究。橡胶树乳管是以蔗糖为原料进行橡胶生物合成的一种功能特化细胞,橡胶烃占其细胞质(胶乳)干物质的90％以上,推测TPS 基因可能参与胶乳蔗糖代谢和产胶调控。发现橡胶树基因组上共有14 个TPS 基因(HbTPS),其中4个归为I 类(HbTPS1～4)
