“…Prolonged existence of autophagic processes may contribute to the elevated embryo induction observed after n-butanol treatment, enabling the formation of new, potentially embryogenic cells during the later phase of anther culture, which is generally not yields new embryos. According to Varnier et al (2009), programmed cell death during microspore embryogenesis is a significant factor that lowers the number of embryos and regenerated plants. In our experiments, clear signs of programmed cell death were observed in both cold-treated control and n-butanol treated cultures at the 14 th day of culture.…”

“…The cytological study demonstrated that the abnormal microspores first appeared at the later-uninucleate stage. During the development of the anther, tapetal cell degradation and anther dehiscence are recognized features of PCD in male sterility [ 16 , 18 , 41 45 ]; this begins with nuclear DNA fragmentation to form nucleosomes (≥180 bp), and subsequently abnormal cytological structures become visible. As the morphological characteristics of pollen abortion lag far behind its nuclear DNA fragmentation, the use of cytological observation alone delays the determination of the initial period of male sterility.…”

“…We used TUNEL assay and DAPI staining to further demonstrate the above abnormal processes, and showed that the SQ-1-treated plants underwent premature PCD of the tapetal cells. Additionally, anther dehiscence is also a consequence of PCD [ 44 , 45 ]. Similarly, in this study, we also observed that PCD was also present in controls and treatments, especially in the trinucleate stage (before anther dehiscence).…”

“…Вероятно, протеинкиназы вовлекаются в транс дукцию сигнала, вызванного эффектом голодания, и вли яют на экспрессию генов и регуляцию клеточного цикла (Garrido et al, 1995). Голодание вызывает экспрессию генов HSPs in vitro, что подтверждает роль молекулярных шаперонов в клеточном перепрограммировании (Wang et al, 1999;Varnier et al, 2009).…”
