A novel tapetum-specific cDNA clone of rice, its corresponding gene designed as RA39, is isolated by RNA subtractive hybridization, differential screening and rapid amplification of cDNA ends. The RA39 cDNA is 1013 bp...
The distribution of Ca2+ in the anthers of wheat was observed using cytochemical method of potassium antimonite. At the later tetrad stage, Ubisch bodies carrying Ca2+ were observed on the inner surface of tapetum, in...
