Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, EarlyView.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

Epigenetic changes accompany developmental programmed cell death in tapetum cells

, 2014
10 páginas, 8 figuras --PAGS nros. 16-29(2014)The tapetum, the nursing tissue inside anthers, undergoes cellular degradation by programmed cell death (PCD) during late stages of microspore–early pollen development.

HSP101‐encoding NEO‐TETRAPLOID RICE FERTILITY GENE 1 regulates tapetum development through interaction with SAPK2 in polyploid rice

Journal of Integrative Plant Biology, EarlyView.
In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

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

An Arabidopsis F-box protein regulates tapetum degeneration and pollen maturation during anther development

, 2010
The Arabidopsis anther has a bilateral symmetry with four lobes, each consisting of four distinct layers of somatic cells from the outer to inner side: epidermis, endothecium, middle layer and tapetum. The tapetum is a layer of cells comprising the inner

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

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.

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.

Specification of tapetum and microsporocyte cells within the anther

, 2014
Flowering plants form male reproductive cells (microsporocytes) during sporophytic generation, which subsequently differentiate into multicellular male gametes in the gametophytic generation.
