Abstract:
... Pollen mother cell (PMC) development in the apomictic Boechera species B. holboellii, B. gunnisoniana and B. divaricarpa were investigated by various cytological methods. In prophase I, in triploid species B. holboellii and B. gunnisoniana the individual chromosomes condensed into long strands within the nucleus. Then, in metaphase I, each PMC formed a restitutional nucleus thereby bypassing the r ...

The expression of OsTUB4, one of eight β-tubulin isotypes identified in the rice genome, was characterized. OsTUB4 was expressed in root primodia and the shoot apical meristem in basal parts of the leaf sheath in rice seedlings. OsTUB4 transcript abundance in leaf sheath increased by treatment with g ...
