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 ...

Aerobic fermentation during tobacco pollen development [PDF]
Plant Molecular Biology, 1997 In vegetative organs of plants, the metabolic switch from respiration to fermentation is dictated by oxygen availability. The two genes dedicated to ethanolic fermentation, pyruvate decarboxylase and alcohol dehydrogenase, are induced by oxygen deprivation and the gene products are active under oxygen stress. In pollen, these two genes are expressed in

Polymerase IV Plays a Crucial Role in Pollen Development in Capsella[OPEN]
The Plant Cell, 2020 Unlike in Arabidopsis, loss of function of Polymerase IV in the Brassicaceae species Capsella rubella causes microspore arrest, revealing an important role for Polymerase IV in pollen development.

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 ...

Abundance of Insects Inhabiting the Male Strobili of Red Pine [PDF]
, 2017 (excerpt) Southwood (1973) concluded that pollen feeding was probably the first step in the development of the phytophagous habit in insects, because pollen, compared with plant foliage, is rich in nutrients and low in sewndary defense substances ...

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

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
