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 ...

Differential Expression Profiling Reveals Stress-Induced Cell Fate Divergence in Soybean Microspores
Plants, 2020 Stress-induced microspore embryogenesis is a widely employed method to achieve homozygosity in plant breeding programs. However, the molecular mechanisms that govern gametophyte de- and redifferentiation are understood poorly.

Microspore embryogenesis in barley: anther pre-treatment stimulates plant defence gene expression [PDF]
Microspore embryogenesis (ME) is a process in which the gametophytic pollen programme of the microspore is reorientated towards a new embryo sporophytic programme.

The making of gametes in higher plants [PDF]
, 2005 Higher plants have evolved to be one of the predominant life forms on this planet. A great deal of this evolutionary success relies in a very short gametophytic phase which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in

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.

BMC Plant Biology, 2016 Microspore embryogenesis describes a stress-induced reprogramming of immature male plant gametophytes to develop into embryo-like structures, which can be regenerated into doubled haploid plants after whole genome reduplication. This mechanism is of high

Doubled haploid ramets via embryogenesis of haploid tissue cultures [PDF]
, 2010 Tissue culture in the oil palm business is generally concerned with the multiplication (clonal production) of dura, pisifera and tenera palms. These are all normal diploids (2n=2x=36).

Plant Biotechnology Journal, EarlyView.ABSTRACT High temperature has posed significant challenges to global agriculture, markedly leading to reduced fertility and yield losses in tomato (Solanum lycopersicum). Therefore, thermotolerance‐conferring genes and loci are needed to further improve cultivated tomatoes.

Plant Biotechnology Journal, EarlyView.ABSTRACT Protein‐based biopesticides and biostimulants are critical for the future of sustainable agriculture, yet their utility is severely limited by inefficient delivery into plant cells. Traditional cell‐penetrating peptides enable protein uptake but lack the efficiency, systemic activity and scalability required for crop production.

Pollen grain of barley (Hordeum vulgare L.) - pattern of development
Acta Societatis Botanicorum Poloniae, 2014 Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast
