The generic data matrix and database of adult morphology of Tenthredinoidea were set up. The polarization of each morphologic character was concluded based on the evolutionary morphology, the inner group comparision and fossils analysis. The generic cladogram of Tenthredinoidea was calculated by PC586 computer using Hennig86 program. A new classification system for Tenthredinoidea was proposed based on the analysis of the cladogram. The tribal cladistic biogeography of the superfamily was analyzed using Diva program.

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.
