Using hybrid rice variety Shu-hui 527 and "2330" from the southwest university of science and technology as the materials, the effect of crude toxin from Phyricularis.cav on the induction, growth and differentiation of callus from rice mature embryos were studied in the present rice area of Sichuan.

以生产上大面积推广的杂交水稻恢复系蜀恢527和西南科技大学自育优质高产杂交水稻恢复系&2330&为材料，研究目前四川地区的稻瘟优势菌株稻瘟菌粗毒素对水稻成熟胚愈伤组织诱导、生长和分化的影响。

Longan1 expressed from the embryogenic callus stage to the globular embryoid stages. Longan2 expressed in the whole process of longan somatic embryogenesis, which was probably a housekeeping gene. Longan3 expressed from the globular embryoid stage to the torpedo-shaped embryoid stage. Longan4、longan4'expressed only at the cotyledonary embryoid stage.

碱基序列分析表明，longan1在3'端存在一个开放阅读框，longan2、longan3分别在5'端存在一个开放阅读框，longan1在3'方向，longan2、longan3在5'方向均没有终止密码子，所以可能往相应的方向延伸仍为各自的ORF，因此可以通过RACE或者筛选cDNA文库的办法来获得它们的全长cDNA。

Longan somatic embryogenesis occurred through the following stages—embryogenic callus, globular embryoid, heart-shaped embryoid, torpedo-shaped embryoid, cotyledonary embryoid and matured cotyledonary embryoid, which was similar to that of zygotic embryo.
