Auxin controls
The Plant Journal, 2013 SummaryIt has been suggested that, in Arabidopsis, auxin controls the timing of anther dehiscence, possibly by preventing premature endothecium lignification. We show here that auxin content in anthers peaks before the beginning of dehiscence and decreases when endothecium lignification occurs.

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.

AN OVERVIEW OF POLLEN AND ANTHER WALL DEVELOPMENT IN Catalpa bignonioides Walter (BIGNONIACEAE)
Trakya University Journal of Natural Sciences, 2017 Anther development in Catalpa bignonioides Walter was investigated from the sporogenous cell to the mature pollen grain stages to determine whether the pollen and anther wall development follows the basic scheme in angiosperms.

Ultrastructural study of anther parasitism of Ficus laevigata by Ficophagus laevigatus (Aphelenchoididae) [PDF]
Journal of Nematology, 2023 Transmission electron microscopy (TEM) was used to compare the ultrastructural differences between healthy male florets (anthers) and one floret parasitized by Ficophagus laevigatus in late phase C syconia of Ficus laevigata from southern Florida ...

Sporogenesis and development of gametophytes in an endangered plant, Tetracentron sinense Oliv
Biological Research, 2012 The sporogenesis and development of gametophytes in Tetracentron sinense Oliv. were studied with light microscopy. The anther has four microsporangia; its primary anther wall consists of an epidermis, an endothecium, one or two middle layers and one ...

Maize Anther Development Involves Translated Open Reading Frames From 3' Untranslated Regions. [PDF]
Adv Sci (Weinh)This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80-Controlled Lipid Metabolism. [PDF]
Plant Biotechnol JABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Single-Cell Transcriptome Atlas and Dynamic Regulatory Mechanisms of Anther Development in Alfalfa (Medicago sativa L.). [PDF]
Plant Biotechnol JABSTRACT Anthers consist of various specialised cell types and play a significant role in plant reproduction. Although the molecular mechanisms underlying anther development and regulation have been extensively studied, the single‐cell transcriptional landscape and dynamic regulation during anther development in M. sativa remain largely unexplored.
