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 ...

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.

Comparative transcriptome analysis reveals key insights into male sterility in Salvia miltiorrhiza Bunge [PDF]
PeerJ, 2021 Background Large-scale heterosis breeding depends upon stable, inherited male sterility lines. We accidentally discovered a male sterility line (SW-S) in the F1progeny of a Salvia miltiorrhiza Bunge from Shandong, China (purple flowers) crossed with a S.
