Global transcriptome analysis reveals potential genes associated with genic male sterility of rapeseed (Brassica napus L.)

Frontiers in Plant Science, 2022
Rapeseed is the third leading source of edible oil in the world. Genic male sterility (GMS) lines provide crucial material for harnessing heterosis for rapeseed. GMS lines have been widely used successfully for rapeseed hybrid production.

AtZAT4, a C₂H₂-Type Zinc Finger Transcription Factor from Arabidopsis thaliana, Is Involved in Pollen and Seed Development

Plants, 2022
Pollen plays an essential role in plant fertility by delivering the male gametes to the embryo sac before double fertilization. In several plant species, including Arabidopsis, C2H2-type zinc-finger transcription factors (TFs) have been involved in ...

The impact of heat stress in plant reproduction

Frontiers in Plant Science, 2023
The increment in global temperature reduces crop productivity, which in turn threatens food security. Currently, most of our food supply is produced by plants and the human population is estimated to reach 9 billion by 2050.

Callose Deposition during Pollen Development [PDF]

Plant Physiology, 2020
Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new article investigating pollen formation in cotton ( Gossypium hirsutum ), we now know that a pollen-specific protein regulates callose deposition by inhibiting the action of ...

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

, 1988
Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several

Divisions of labor in the thiamin biosynthetic pathway among organs of maize

Frontiers in Plant Science, 2014
The B vitamin thiamin is essential for central metabolism in all cellular organisms including plants. While plants synthesize thiamin de novo, organs vary widely in their capacities for thiamin synthesis. We use a transcriptomics approach to appraise the

Pollen Development and Stainability in Vicia faba L. and Lupinus angustifolius L.

Agriculture, 2023
Commercially, leguminous crops (Fabaceae) are the second most important group of cultivated plants, just after grasses (Poaceae). This study focuses on the analysis of pollen development and stainability in two species belonging to the Fabaceae family ...

Hormonome Dynamics During Microgametogenesis in Different Nicotiana Species

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 ...

Observations and modelling of birch pollen emission and dispersion from an isolated source [PDF]

, 2014
The occurrence of allergic diseases in western countries increased during the last decades due to greater awareness towards a hygienic lifestyle. The hygiene hypothesis relates the reduced expo- sure to microbial pollution to an underdevelopment of the
