These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。
