Biology and Function of miR159 in Plants
Plants, 2019 MicroR159 (miR159) is ancient, being present in the majority of land plants where it targets a class of regulatory genes called GAMYB or GAMYB-like via highly conserved miR159-binding sites.

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 ...

Some cytological, ecological and evolutionary aspects of pollination
Acta Societatis Botanicorum Poloniae, 2014 Different types of pollen dispersing units are described. The pollen of angiosperms may be dispersed in monads, tetrads, polyads, massulae or compact pollinia.

Evaluation of mitotic activity in tapetal cells of grapevine (Vitis L.)
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021 The knowledge with reference to the grapevine tapetum has been centered on its anatomy/morphology and hardly anything at all is known about its mitotic activity throughout the microsporogenesis. The aim of this study was to ascertain the mitotic activity

Evolution of an Apomixis-Specific Allele Class in Supernumerary Chromatin of Apomictic Boechera
Frontiers in Plant Science, 2022 Asexual reproduction through seeds in plants (i.e., apomixis) is a heritable trait, and apomixis- linked loci have been identified in multiple species. However, direct identification of genomic elements is typically hindered as apomixis-linked loci and ...

Origin and structure of Ubisch bodies in Pinus sylvestris
Acta Societatis Botanicorum Poloniae, 2014 In Pinus sylvestris Ubisch bodies are produced repeatedly, and each crop is formed at a distinct phase in the secretory cycles of tapetal cells. While each production has a Ubisch body wall similar to the then current state of the exine with regard to ...

Epigenetic Regulation of Heat Stress in Plant Male Reproduction
Frontiers in Plant Science, 2022 In flowering plants, male reproductive development is highly susceptible to heat stress. In this mini-review, we summarized different anomalies in tapetum, microspores, and pollen grains during anther development under heat stress.
