The RiceTapetum Degeneration RetardationGene Is Required for Tapetum Degradation and Anther Development [PDF]

The Plant Cell, 2006
AbstractIn flowering plants, tapetum degeneration is proposed to be triggered by a programmed cell death (PCD) process during late stages of pollen development; the PCD is thought to provide cellular contents supporting pollen wall formation and to allow the subsequent pollen release.

SWOLLEN TAPETUM AND STERILITY 1 is required for tapetum degeneration and pollen wall formation in rice

Plant Physiology, 2022
Abstract The pollen wall is important for protecting the male gametophyte and for fertilization. The lipid components of the pollen wall are mainly synthesized and transported from the sporophytic tapetum. Although several factors related to lipid biosynthesis have been characterized, the molecular mechanisms underlying lipid ...

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

Autophagy-mediated degradation of integumentary tapetum is critical for embryo pattern formation

Nature Communications
Autophagy modulates the degradation and recycling of intracellular materials and contributes to male gametophyte development and male fertility in plants. However, whether autophagy participates in seed development remains largely unknown.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

GENE NETWORKS CONTROLLING ANTHER TAPETUM DEVELOPMENT IN BARLEY (Hordeum vulgare) DURING EARLY ANTHER DEVELOPMENT [PDF]

, 2021
The tapetum, the innermost somatic cell layer in anther locule, directly communicates with the developing gametophytic cells, providing essential nutrients, critical components for their development and maturity.
