Male Gametophyte Development. [PDF]

open access: yesThe Plant Cell, 1993
Pollen development offers the opportunity to study cell fate, cell patterning, cell polarity, and cell signaling-in this sense, pollen development can serve as a microcosm for all the in- teresting questions facing plant biologists today. The events that culminate in the formation and release of the pollen grain from the plant begin with meiosis and ...

Effects on Plant Growth and Reproduction of a Peach R2R3-MYB Transcription Factor Overexpressed in Tobacco

open access: yesFrontiers in Plant Science, 2019
In plants, anthocyanin production is controlled by MYB and bHLH transcription factors. In peach, among the members of these families, MYB10.1 and bHLH3 have been shown to be the most important genes for production of these pigments during fruit ripening.

The Role of Cytokinin in Female Gametophyte Development in Arabidopsis [PDF]

open access: yes, 2013
Plants, unlike animals, have distinct haploid and diploid phases of their life cycle. The haploid female gametophyte develops within the diploid maternal sporophytic tissue.
