IPA1 gene controlled paddy has increased in height, sturdy stem, number of tillers decreased, grains per panicle and dry grains weight increased significantly. In this study, the homology of IPA1 gene in 26 types of plant from 15 families was analyzed, and thus constructed its phylogenetic tree. The results of phylogenetic tree construction based on its amino acid sequence showed that the species from the same family, such as Gramineae, Rosaceae and Palmaceae, were well clustered for different branches and had high support rates. Furthermore, we constructed the phylogenetic tree based on its CDS sequence, and the species of Gramineae was well clustered, and the support rate was 100%. Our results indicate that IPA1 has high homology in higher class of plants, especially in the Gramineae, which is of great significance for us to further study the yield of rice and other gramineous species.

s with time and concentration effect (3) Achilla glauca extract could make the chromosome bridge, chromosome fragment, chromosome lag in the root tip cells of Vicia faba and increase in micronucleus rate. The results showed that the water extract of Solidago canadensis had different degree of inhibition and damage to silkworm root tip cells; it also had some genetic toxicity and rapid diffusion ability.
