GhGPAT12/25 Are Essential for the Formation of Anther Cuticle and Pollen Exine in Cotton (Gossypium hirsutum L.)

Frontiers in Plant Science, 2021
Glycerol-3-phosphate acyltransferases (GPATs), critical for multiple biological processes like male fertility, have been extensively characterized. However, their precise functions and underlying regulatory mechanism in cotton anther development are ...

Microspore embryogenesis in barley: anther pre-treatment stimulates plant defence gene expression

, 2009
Microspore embryogenesis (ME) is a process in which the gametophytic pollen programme of the microspore is reorientated towards a new embryo sporophytic programme.

Anther Ontogeny and Microsporogenesis in <i>Helianthus annuus</i> L. (Compositae)

Notulae Scientia Biologicae, 2015
In this study, anther ontogeny and microsporogenesis were analysed in Helianthus annuus L. The undifferentiated anther is ovoid-shaped and the differentiation starts with the appearance of archesporial cells. Mature anthers are tetrasporangiate.

A RING-type E3 ligase controls anther dehiscence by activating the jasmonate biosynthetic pathway gene DEFECTIVE IN ANTHER DEHISCENCE1 in Arabidopsis

, 2014
Suppression of expression of DAF [DEFECTIVE IN ANTHER DEHISCENCE1 (DAD1)-Activating Factor], a gene that encodes a putative RING-finger E3 ligase protein, causes non-dehiscence of the anthers, alters pollen development and causes sterility in 35S:DAF ...

SPL8, an SBP-box gene that affects pollen sac development in Arabidopsis [PDF]

, 2003
SQUAMOSA PROMOTER BINDING PROTEIN-box genes (SBP-box genes) encode plant-specific proteins that share a highly conserved DNA binding domain, the SBP domain.

Comparative Oligo‐FISH Mapping Illuminates Chromosomal Evolution Among Rutaceae Species Diverged Over 50 Million Years

Advanced Science, EarlyView.
Oligonucleotide‐based fluorescence in situ hybridization probes were developed in the model citrus species Citrus maxima. These probes were applied to comparative karyotyping across 14 species in the Rutaceae family. This analysis revealed chromosomal evolution in lineages that diverged from Citrus nearly 52 million years ago.

Understanding the role of gibberellin signalling in wheat anther development during heat stress [PDF]

, 2016
High temperature (HT) stress during wheat male reproductive development causes irreversible damage to the anther tapetum layer and the developing microspores it supports, resulting in reduced yield.

ROLE OF POLYAMINES IN INHIBITION OF ETHYLENE BIOSYNTHESIS AND THEIR EFFECTS ON RICE ANTHER CULTURE DEVELOPMENT

, 2016
The polyamines such as putrescine, spermidine, and spermine were reported to increase green plant regeneration in rice anther culture. Low response of anther culture of rice sub-species indica may be improved with the addition of putrescine in the ...

Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation

Advanced Science, EarlyView.
Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.

A Virus‐Inducible E3–RLCK–MADS Module Coordinates Suppression of Plant Immunity and Fertility in Rice

Advanced Science, EarlyView.
ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy
