ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

OsMS188 Is a Key Regulator of Tapetum Development and Sporopollenin Synthesis in Rice

Rice, 2021
Background During anther development, the tapetum provides essential nutrients and materials for pollen development. In rice, multiple transcription factors and enzymes essential for tapetum development and pollen wall formation have been cloned from ...

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Salicylic acid reverses pollen abortion of rice caused by heat stress

BMC Plant Biology, 2018
Background Extremely high temperatures are becoming an increasingly severe threat to crop yields. It is well documented that salicylic acid (SA) can enhance the stress tolerance of plants; however, its effect on the reproductive organs of rice plants has

A Rapid Alkalinization Factor-like Peptide EaF82 Impairs Tapetum Degeneration during Pollen Development through Induced ATP Deficiency

Cells, 2023
In plants, the timely degeneration of tapetal cells is essential for providing nutrients and other substances to support pollen development. Rapid alkalinization factors (RALFs) are small, cysteine-rich peptides known to be involved in various aspects of

A robust biotechnology induces artificial genomic duplication via transient RNAi‐mediated suppression of OSD1 in rice

Journal of Integrative Plant Biology, EarlyView.
Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...

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 ...

Identification of Genetic Loci Conveying Resistance to Fusarium oxysporum f. sp. ciceris Race 0 in Chickpea

Plant Breeding, EarlyView.
ABSTRACT Chickpea (Cicer arietinum L.) is a legume that is widely consumed around the world due to its nutritional content. Fusarium oxysporum f. sp. ciceris is a serious, destructive pathogen that causes fusarium wilt disease and affects chickpea production.

Application of the comet assay in studies of programmed cell death (PCD) in plants

Acta Societatis Botanicorum Poloniae, 2014
Programmed cell death (PCD) in plants is an intensively investigated process. One of the main characteristics of PCD in both animal and plant organisms is the non-random, internucleosomal fragmentation of nuclear DNA, usually analysed using total DNA gel
