In the fin219-null mutant background, GUS staining can be detected in the hydathode of cotyledons, and the guard cells around hydathodes. GUS staining are also found in the base of trichomes, hypocotyls and roots. In contrast, in the phyA mutant background, GUS-FIN219 was not expressed in the hypocotyls.
结果发现转殖在fin219-null突变株背景下,FIN219会特别表现在植株叶缘出水孔与附近的保卫细胞及毛茸基部、初生叶、下胚轴、根部等处,然而在phyA缺失的时候植株幼苗的FIN219则不会在下胚轴表现。

The FTIR analysis indicated that there was no or very little suberin in endodermis radial wall of cotyledon compared with primary and two-year-old leaves. Furthermore, the content of suberin in endodermis of the primary leaves was lower than that of two-year-old leaves.
根据FTIR的检测结果显示:子叶内皮层细胞径向壁不含木栓质或极少,2 a生针叶内皮层细胞径向壁木栓质含量高于初生叶。
-
The energy-dispersive X-ray analysis showed that the endodermis with Casparian strips in primary and two-year-old leaves functioned as apoplastic barriers against Na and Cl. However, no blockage of Na and Cl in cotyledon was observed when they passed endodermis.
对相应区域的X射线微区分析表明,子叶内皮层对Na和Cl在质外体运输中不起障碍作用,而初生叶与2 a生针叶内皮层阻碍Na和Cl以质外体途径进入维管组织。
-
The fluorescence microscopy showed that Casparian strips were absent from cotyledon endodermis, while the radial wall of endodermis in primary and two-year-old leaves were occupied with Casparian strips.
通过荧光显微观察发现,白皮松子叶内皮层不具凯氏带,而初生叶及2 a生针叶均存在凯氏带加厚现象。

The salty gland of Messerschmidia sibirica is developed from epidermic cell of stem and leaf.
利用石蜡切片法研究了砂引草茎叶的解剖结构,尤其是对泌盐腺的位置、泌盐腺的形态结构及泌盐腺的发生发育过程进行了系统的研究,结果表明:砂引草茎的初生结构维管束是外韧的,且其有10-12束,大小不等,髓和髓射线发达;叶的上下表皮细胞各一层,栅栏组织与海绵组织分化明显。

The cellular structure, chemical characterization of foliar endodermis and element cellular distribution were investigated in Pinus bungeana leaves by the fluorescence microscope, Fourier transform infrared microspectroscopy and energy-dispersive X-ray analysis.
应用荧光显微技术、傅里叶变换显微红外光谱分析、扫描电镜及X-射线能谱微区分析等手段,对白皮松子叶、初生叶及2 a生针叶内皮层细胞径向壁的显微结构特征、化学成分,以及在叶子横切面上Na和Cl的微区分布进行分析。

vascular bundle:维管束
维管束(vascular bundle)是维管植物(蕨类植物、裸子植物和被子植物)的叶和幼茎等器官中,由初生木质部和初生韧皮部共同组成的束状结构. 维管束彼此交织连接,构成初生植物体输导水分,无机盐及有机物质的一种输导系统--维 类型根据初生木质部与初生韧皮部排列方式的不同,
-
secondary xylem:次生木质部
根据出现时间的早晚和来源,木质部可划分为初生木质部(primary xylem)和次生木质部(secondary xylem). 出现最早,在茎和叶中,原生木质部着生于伸长活动活跃的组织中,因为它不能跟随着伸长,所以会被拉伸而导致破坏,形成一片原生木质部缺失(Protoxylemlacuna)区域.
