TCP24 modulates secondary cell wall thickening and anther endothecium development [PDF]
Frontiers in Plant Science, 2015 miR319-targeted TCP genes are believed to regulate cell division in leaves and floral organs. However, it remains unknown whether these genes are involved in cell wall development. Here, we report that TCP24 negatively regulates secondary wall thickening

Structure of Anther Epidermis and Endothecium, Production of Pollen, and Content of Selected Nutrients in Pollen Grains from Six Rubus idaeus L. Cultivars [PDF]
Agronomy, 2021 Poland is the largest European Union producer of Rubus idaeus. This species provides insects with nectar and pollen from June to September. The rationale behind the present research is the increasing commercial production and the use of food attractants ...

The endothecium — a neglected criterion in taxonomy and phylogeny?
Bothalia: African Biodiversity & Conservation, 1983 A method has been devised for the screening of the endothecium in flowering plants, principally with a view to describing the cell wall thickening. A scheme of nomenclature and coding has been proposed, which permits a more detailed and unambiguous ...

Knockdown of Arabidopsis ROOT UVB SENSITIVE4 Disrupts Anther Dehiscence by Suppressing Secondary Thickening in the Endothecium [PDF]
Plant and Cell Physiology, 2019 AbstractROOT UV-B SENSITIVE4 (RUS4) encodes a protein with no known function that contains a conserved Domain of Unknown Function 647 (DUF647). The DUF647-containing proteins RUS1 and RUS2 have previously been associated with root UV-B-sensing pathway that plays a major role in Arabidopsis early seedling morphogenesis and development.

The LoMYB26/LoJAZ4-LoCOMT module regulates anther dehiscence via Jasmonic acid-mediated endothecium lignification in lily [PDF]
Journal of Advanced ResearchTimely anther dehiscence is a key step for successful sexual reproduction in plants. Secondary cell wall thickening of anther endothecium is a vital process during anther dehiscence that provides an indispensable mechanical force for successful dehiscence.

The systematic significance of the endothecium in Begoniaceae [PDF]
Botanical Journal of the Linnean Society, 1999 The endothecial thickening patterns in 173 species, representing the three genera of Begoniaceae, were investigated using cleared macerated anthers. Begoniaceae contain taxa with U-shaped thickenings, perforate base plates, entire base plates, tympanate base plates, anticlinal bars, and taxa that lack endothecial thickenings.

Systematics and floral micromorphology of core Aster and its related groups (Asteraceae, Astereae): Taxonomic significance and phylogenetic insights [PDF]
PhytoKeysFour floral microcharacters were examined within 40 species of core Aster and its related groups in the genus Aster L. (Asteraceae, Astereae). These microcharacters included corolla lobe, style base, endothecium cell wall thickening, and the relative ...

Normal Structure and Function of Endothecium Chloroplasts Maintained by ZmMs33-Mediated Lipid Biosynthesis in Tapetal Cells Are Critical for Anther Development in Maize [PDF]
Molecular Plant, 2020 Genic male sterility (GMS) is critical for heterosis utilization and hybrid seed production. Although GMS mutants and genes have been studied extensively in plants, it has remained unclear whether chloroplast-associated photosynthetic and metabolic activities are involved in the regulation of anther development.

Molecules and Cells, 2008 Cytokinins are essential hormones in plant development. Arabidopsis histidine-containing phosphotransfer proteins (AHPs) are mediators in a multistep phosphorelay pathway for cytokinin signaling. The exact role of AHP4 has not been elucidated. In this study, we demonstrated young flower-specific expression of AHP4, and compared AHP4-overexpressing (Ox)
