Hormonome Dynamics During Microgametogenesis in Different Nicotiana Species [PDF]
Frontiers in Plant Science, 2021 Plant microgametogenesis involves stages leading to the progressive development of unicellular microspores into mature pollen. Despite the active and continuing interest in the study of male reproductive development, little is still known about the ...

The Plant Journal, Volume 112, Issue 5, Page 1281-1297, December 2022., 2022 Significance Statement During anther development, the tapetal cells that surround the sporocytes have essential roles in male meiotic progression and the formation of mature pollen grains. In tomato, despite its importance for breeding purposes, the interaction between the tapetum and sporogenous tissues is poorly understood.

The rice eukaryotic translation initiation factor 3 subunit f (OseIF3f) is involved in microgametogenesis [PDF]
Frontiers in Plant Science, 2016 Microgametogenesis is the postmeiotic pollen developmental phase when unicellular microspores develop into mature tricellular pollen. In rice, microgametogenesis can influence grain yields to a great degree because pollen abortion occurs more easily ...

The effects of heat stress on male reproduction and tillering in Sorghum bicolor
Food and Energy Security, Volume 12, Issue 6, November 2023., 2023 Abstract Due to global climate change, heat stress is increasingly harming the growth, development, overall biomass, and grain yield of numerous crops. Heat stress impairs pollen development and thus reduces seed set in Sorghum bicolor (L.) Moench; however, the effects of heat stress on anther development at specific stages and tiller formation remain ...

Frontiers in Genetics, 2020 In plants, F-box proteins (FBPs) constitute one of the largest superfamilies of regulatory proteins. Most F-box proteins are shown to be an integral part of SCF complexes, which carry out the degradation of proteins and regulate diverse important ...

RUVBL proteins are involved in plant gametophyte development
The Plant Journal, Volume 114, Issue 2, Page 325-337, April 2023., 2023 Significance Statement We show that RUVBL1 and RUVBL2, plant orthologues of human Pontin and Reptin, are essential for the proper development of both male and especially female gametophytes in Arabidopsis. SUMMARY The proper development of male and female gametophytes is critical for successful sexual reproduction and requires a carefully regulated ...
