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 ...

Live-cell fluorescence imaging of microgametogenesis in the human malaria parasite Plasmodium falciparum. [PDF]
PLoS Pathogens, 2022 Formation of gametes in the malaria parasite occurs in the midgut of the mosquito and is critical to onward parasite transmission. Transformation of the male gametocyte into microgametes, called microgametogenesis, is an explosive cellular event and one ...

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 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.

Whole-genomic DNA amplifications from individually isolated sweet sorghum microspores. [PDF]
Appl Plant Sci, 2022 Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Methodologies and Considerations in Evaluating Heat Stress Response and Thermotolerance of Pollen Grains. [PDF]
Physiol PlantABSTRACT Elevated temperatures severely disrupt pollen function, posing a major threat to agricultural productivity. While research into pollen thermotolerance is rapidly expanding, the quest to identify and develop heat‐tolerant crops is challenged by a lack of consistent methodological considerations and experimental design principles.
