摘要 植物根中的内皮层发育一般经历两个阶段,首先形成可以阻挡质外体运输途径的木质素沉积,即凯氏带形成阶段;其次生成可以阻断跨细胞运输的木栓质沉积,即凯氏带加厚阶段。内皮层凯氏带的形成与加厚导致了外界的水和溶质只能通过共质体运输途径进入中柱,保障了植物从外界向内部运输物质时的选择能力。本文通过对84K杨树施加聚乙二醇(PEG)模拟干旱胁迫以及施加脱落酸(ABA),发现PEG模拟的干旱胁迫和ABA均能够促进凯氏带加厚,ABA参与了凯氏带木栓化形成,为植物根内皮层发育调控研究提供了新的实验依据。 The development of endodermis in plant roots generally goes through two stages:formation stage of Casparian strip with the lignin deposition,which can block the apoplastic pathway,and thickening stage of Casparian strip with suberin lamellae formation,which can block the coupled trans-cellular pathway.The formation and thickening of the Casparian strip in the endodermis results in that the external water and solute can only enter the stele through the symplastic pathway,which guarantees the selection ability of plants when they transport materials from the outside to the inside.Through the application of PEG and ABA on 84 K poplar(Populus alba×P.glandulosa cv′84k′),it was found that PEG simulated drought stress and ABA could promote the thickening of Casparian strip,and ABA signal participated in the formation of suberin lamellae in Casparian strip,which laid a foundation for further research on the regulation of root endodermis development.
