Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

结果显示:接种后6 d的根尖分生区、伸长区出现膨大、对称的根结,根中心的原形成层细胞分化出巨型细胞;10 d在根毛区及以上部位出现既有对称又有偏于一侧的根结,周围有原生木质部导管出现,根结中巨型细胞阻断了导管;16 d次生维管组织提早出现;20~30 d导管纵向排列无序,形状扭曲,皮层中有新维管组织产生。

Tillering in rice is one of important agronomic trait that determine grain yield. Tillering is also of developmental importance because tiller is special type of branches which is quite different from that of dicot plants. M0C1 gene can control formation of axillary meristematic tissues and tillering bud in rice, and its subsequent outgrowth.

All observations showed that both cotyledons of European Gesneriaceae species ceased to grow in early stages and thus no prolonged meristematic activity could be observed.
