Global dissection of alternative splicing uncovers transcriptional diversity in tissues and associates with the flavonoid pathway in tea plant (Camellia sinensis)

BMC Plant Biology, 2018
Background Alternative splicing (AS) regulates mRNA at the post-transcriptional level to change gene function in organisms. However, little is known about the AS and its roles in tea plant (Camellia sinensis), widely cultivated for making a popular ...

Studies on the fertilization of tea plant.

Japanese Journal of Breeding, 1956
The tea plant has many flowers, but they almost drop off after flowering, and the fruiting-rate is 20-30% in the crossed flowers or 3-10% in the selfed flowers. To get the fundamental knowledge on the breeding and seed production of the tea plant, we investegated cytologically, in the crossed flowers aswell as selfed ones of the same tea plant, the ...
