Use of CRISPR/Cas9-Based Gene Editing to Simultaneously Mutate Multiple Homologous Genes Required for Pollen Development and Male Fertility in Maize

Cells, 2022
Male sterility represents an important trait for hybrid breeding and seed production in crops. Although the genes required for male fertility have been widely studied and characterized in many plant species, most of them are single genic male-sterility ...

Various tomato cultivars display contrasting morphological and molecular responses to a chronic heat stress

Frontiers in Plant Science, 2023
Climate change is one of the biggest threats that human society currently needs to face. Heat waves associated with global warming negatively affect plant growth and development and will increase in intensity and frequency in the coming years.

RNA N6-Methyladenosine Responds to Low-Temperature Stress in Tomato Anthers

Frontiers in Plant Science, 2021
Cold stress is a serious threat to subtropical crop pollen development and induces yield decline. N6-methyladenosine (m6A) is the most frequent mRNA modification and plays multiple physiological functions in plant development.

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 ...

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

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 ...
