查询词典 pal

The paper studied the physiological characteristics of the leaves of Cotinus coggygria Royal Purple with different colors in autumn. Three kinds of leaf colors were selected to measure the contents of chlorophyll, anthocyanin, phenylalanin ammo-nialyase activity and the water content in the leaves. The results showed that the leaves exhibited red if it had lower chlorophyll content, higher activities of PAL and higher content of anthocyanin. The green leaves had higher chlorophyll content, lower activity of PAL, less content of anthocyanin.

本研究以美国红栌秋季叶片为试材，选取红色，中间色、绿色三种颜色的叶片，测定其叶绿素、花色素苷、苯丙氨酸解氨酶活性及叶片组织中的含水量，讨论其对美国红栌秋季叶片着色的影响，结果表明：美国红栌秋季叶片中，红色叶片叶绿素含量较低，PAL酶活性较高，花青素苷的含量较高，所以叶色呈现红色；绿色叶片中叶绿素含量较高，PAL酶活性较低，花青素苷的含量较少，所以呈现绿色。

Through activating the synthesis of jasmonic acid itself,aboveground application of jasmonia acid could induce the expression of Bx1,Bx9,PAL,PR-1,MPI,FPS and TPS genes,increase DIMBOA content and decrease caffeic acid content in leaves;on the other hand,the systematic induction of gene expression of Bx6,Bx9、PAL and PR-2a,increase of contents of coumaric acid and caffeic acid,and decrease of syringic acid content in the roots were related with the activating of jasmonic acid synthesis in the aboveground.

茉莉酸处理地上部是通过激活茉莉酸自身合成来诱导叶片Bx1、Bx9、PAL、PR-1、MPI、FPS和TPS基因的表达、增加叶片丁布含量及降低咖啡酸含量的，同时系统诱导根系Bx6、Bx9、PAL和PR-2a基因表达、增加香豆酸和咖啡酸含量以及降低丁香酸含量则与激活地上部茉莉酸自身合成相关。
