The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.

结果表明：辐照处理对种胚原球茎的生长和分化有抑制作用，尤其是对根的抑制更为明显；由于种胚原球茎的完整性好，耐受性强，其辐照半致死剂量(LD50)为67.23Gy；流式细胞分析表明，大多数外部形态发生改变的植株其细胞内DNA的倍性发生了改变，出现相当多的非整倍体；此外，辐照产生的变异苗出现茎分叉、叶片缺绿或白绿相间等现象，可能是由于某些基因的表达与关闭引起的。

Division of Anatomy is primarily dedicated to teaching and research in anatomy including vertebrate morphogenesis, oxygen regulation of placental development, neural coding in the hypothalamus, neurogenesis, brain mechanisms of emotion, animal models for schizophrenia, the notochord and vertebral patterning, axon guidance in the developing brain, brain information processing in cerebellar cortex.

解剖学系主要致力于解剖学的教学与研究，研究领域包括脊椎动物形态发生，胎盘发育的氧调整，丘脑下部的神经编码，神经发生，情绪情感的脑机制，神经分裂症动物模型，脊索和脊椎模型，大脑发育时轴索控制，小脑皮层中的脑信息加工等。

The floral morphogenesis of Coptis was observed under scanning electron microscopy. The initiation of all floral organs of the genus is spiral, the petal primordia are slightly retarded, the developmental sequence of the stamens is centripetal,the carpel primordia are conduplicate (i.e., horse-shoe shaped), the ovaries are half closed and the ovary stalk is formed in the developmental process.

本文运用扫锚电子显微镜观察了黄连属植物花的形态发生和发育过程，结果表明，该属植物所有的花部器官均为螺旋状发生，雄蕊为向心式发育，花瓣原基有微弱的延迟发育，心皮原基为对折型，子房为半封闭类型，子房柄是在发育过程中形成的。

Bicoid is one of the important Drosophila genes involved in the control of embryo polarity arid larvae segmentation. The protein encoded by bicoid is a homedomain-containing transcription factor, which organizes a group of polycomb genes expressed in early development of embryo and therefore named morphogen.

Bicoid是调控果蝇胚胎极性及以后分节发生过程的重要基因，这一基因编码的蛋白是一种转录调控因子，对一组早期胚胎发育过程中的多齿基因的表达具有调控作用，并被称为形态发生剂。
