Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley

Journal of Experimental Botany, 2018
Autophagy is activated and plays a role in stress-induced cell death during microspore embryogenesis, along with cathepsin-like C1A protease activities. Autophagy inhibition reduces cell death, improving embryogenesis induction efficiency.

The Major Factors Causing the Microspore Abortion of Genic Male Sterile Mutant NWMS1 in Wheat (Triticum aestivum L.)

International Journal of Molecular Sciences, 2019
Male sterility is a valuable trait for genetic research and production application of wheat (Triticum aestivum L.). NWMS1, a novel typical genic male sterility mutant, was obtained from Shengnong 1, mutagenized with ethyl methane sulfonate (EMS ...

Defective callose walls and cell plates during abnormal meiosis cause male-sterility in the oat mutant zbs1

Journal of Integrative Agriculture, 2016
: During meiosis in flowering plants, degradation of the callose wall in tetrads releases newly produced microspores, which develop into mature pollen grains.

MYB81, a microspore-specific GAMYB transcription factor, promotes pollen mitosis I and cell lineage formation in Arabidopsis.

The Plant Journal, 2019
Sexual reproduction in flowering plants relies on the production of haploid gametophytes that consist of germline and supporting cells. During male gametophyte development, the asymmetric mitotic division of an undetermined unicellular microspore ...

The preprophase band is dispensable for robust cell division orientation in wood‐forming cambium stem cells

New Phytologist, EarlyView.
Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

Advancing Thermotolerance in Beans: Integrating Physiology, Genomics, and Breeding for Climate Adaptation

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

Molecular insights and translational opportunities to enhance heat tolerance in rice

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Association of morphological markers of flower buds and anthers with the pollen developmental stage in Vicia faba L. (Fabaceae)

Frontiers in Plant Science
The precise identification of microspore and pollen at the optimal developmental stages to be induced towards embryogenesis (vacuolated microspores and young pollen) is essential for induction of in vitro androgenesis in plants.
