Morphological and Cytological Characterization of Petaloid-type Cytoplasmic Male Sterility in Camellia oleifera

Abstract: Camellia oleifera is an important woody tree species in China that produces edible oil. Although sterile male C. oleifera plants play an important role in hybrid breeding, the possible cytological characteristics of pollen abortion remain unknown. To characterize the pollen abortion process, a genic petaloid-type sterile male C. oleifera ‘X1’ plant was investigated using a cytological method. The results showed that in mal… Show more

“…Pollen abortion can occur in every stage of the anther development process, and different species show different manifestations (Laser and Lersten, 1972). It has been found that anther browning and petaloid anthers exist in male sterile plants of the Camellia genus (Jiang et al, 2020;Xiong et al, 2019). These two abortion means are also the main routes of abnormal anther development in other plants (Kozik et al, 2012).…”

“…In the subsequent development stages, anticlinal division was maintained only on the ends of the cross section in the petaloid area of anthers. The development of petaloid anthers was described as the development of the connective tissue of the anthers (Xiong et al, 2019), resulting from the high-frequency division of the middle and peripheral anther cells (He et al, 2010). However, in this study, the cells in the middle of the anthers were lightly stained, while the cells at both ends were darkly stained, indicating that the nuclei of the cells at both ends were active and more cells were observed to be in the division phase in these areas.…”
