Gene Regulatory Network for Tapetum Development in Arabidopsis thaliana [PDF]

Frontiers in Plant Science, 2017
In flowering plants, male gametophyte development occurs in the anther. Tapetum, the innermost of the four anther somatic layers, surrounds the developing reproductive cells to provide materials for pollen development.

Ethylene Activates the EIN2-EIN3/EIL1 Signaling Pathway in Tapetum and Disturbs Anther Development in Arabidopsis

Cells, 2022
Ethylene was previously reported to repress stamen development in both cucumber and Arabidopsis. Here, we performed a detailed analysis of the effect of ethylene on anther development.

Comprehensive Insight into Tapetum-Mediated Pollen Development in Arabidopsis thaliana

Cells, 2023
In flowering plants, pollen development is a key process that is essential for sexual reproduction and seed set. Molecular and genetic studies indicate that pollen development is coordinatedly regulated by both gametophytic and sporophytic factors ...

The fibrous tapetum of the horse eye

Journal of Anatomy, 2013
AbstractThe tapetum lucidum is a light‐reflective tissue in the eyes of many animals. Many ungulates have a fibrous tapetum. The horse has one of the largest eyes of any living animal and also has excellent vision in low‐light environments. This study aimed to clarify the macroscopic tapetal shape, relationship between the tapetal thickness and the ...

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

MORPHOLOGICAL AND BIOREFLECTING CHARACTERISTICS OF TAPETUM LUCIDUM IN DOGS AND COWS

Veterinaria, 2013
Tapetum lucidum is the specially modifided, bio-reflecting tissue layer, which at most vertebrates covers the biggest part of the middle eye tunic, the chorioidea.

Abnormal Programmed Cell Death of Tapetum Leads to the Pollen Abortion of Lycium barbarum Linnaeus

Horticulturae, 2022
Programmed cell death (PCD) in tapetum provides nutrients for pollen development. Once this process becomes abnormal, the pollen will be aborted, and sterile lines will be formed. Lycium barbarum L.

Integrated cytological and transcriptomic analysis reveals insights into pollen fertility in newly synthetic Brassica allohexaploids

Frontiers in Plant Science, 2023
Trigenomic Brassica allohexaploids (AABBCC, 2n = 6x = 54) have great potential in oilseed breeding and genetic diversity. However, Brassica allohexaploids do not exist naturally, and the underlying mechanism regulating pollen fertility in artificially ...

Cytological and Molecular Mechanism of Low Pollen Grain Viability in a Germplasm Line of Double Lotus

Plants, 2023
Self-fertilization rate is an essential index of lotus reproductive system development, and pollen activity is a key factor affecting lotus seed setting rate. Based on cytology and molecular biology, this study addresses the main reasons for the low self-
