Carbohydrate metabolism and gene regulation during anther development in an androdioecious tree, Tapiscia sinensis.

ABSTRACT:

Background and aims

Tapiscia sinensis (Tapisciaceae) is a functional androdioecious species with both male and hermaphroditic individuals, and fruit ripening overlaps with flowering in the hermaphroditic individuals. Pollen vitality was lower in the hermaphrodites than in the males. Anther development requires nutrients, and carbohydrates are the basic nutrients; abnormal carbohydrate metabolism will result in pollen abortion. The aim of this research was to gain insight into the relationship between carbohydrate metabolism and the weakening of the male function of hermaphroditic flowers in T. sinensis.

Methods

Observation of morphology and microscopic and sub-microscopic structures was carried out. Sugar measurements and quantitative real-time PCR analysis were performed fo
