Cryoimmobilized anther analysis reveals new ultrastructural insights into Rhynchospora (Cyperaceae) asymmetrical microsporogenesis [PDF]
Frontiers in Plant ScienceIntroductionThe Cyperaceae family is distinguished by holocentric chromosomes and a distinctive microsporogenesis process, which includes inverted meiosis, asymmetric tetrad formation, selective cell death, and the formation of pseudomonad pollen ...

A Review of the Developmental Processes and Selective Pressures Shaping Aperture Pattern in Angiosperms [PDF]
Plants, 2022 Pollen grains of flowering plants display a fascinating diversity of forms. The observed diversity is determined by the developmental mechanisms involved in the establishment of pollen morphological features.

Microsporogenesis of Apricot Cultivars in Hungary
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2013 Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature.

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

Evaluation of the course of microsporogenesis in some selected peach (Prunus persica L./Batsch) cultivars [PDF]
Acta Agriculturae Serbica, 2014 The evaluation of the microsporogenesis process was performed from January to April within the period of 2011-2013. The experiment involved 15 peach cultivars and the control cultivar Redhaven. The course of microsporogenesis was evaluated on the base of

Flower bud development of almond cultivars based on three different methods
Folia Horticulturae, 2023 Flower bud development of fruit trees plays a key role in their climatic adaptation. It is closely related to dormancy release that determines winter frost susceptibility. Detailed characterisation of flower bud development of 25 almond (Prunus amygdalus

Microsporogenesis and systematics of Aristolochiaceae [PDF]
Botanical Journal of the Linnean Society, 2001 Within Aristolochiaceae, a secretory tapetum and orbicules are ubiquitous, but both simultaneous and successive types of microsporogenesis occur. Simultaneous cytokinesis is apparently plesiomorphic within the order Piperales, in which Aristolochiaceae are now placed.

Polyamines in Pollen: From Microsporogenesis to Fertilization [PDF]
Frontiers in Plant Science, 2016 The entire pollen life span is driven by polyamine (PA) homeostasis, achieved through fine regulation of their biosynthesis, oxidation, conjugation, compartmentalization, uptake, and release. The critical role of PAs, from microsporogenesis to pollen-pistil interaction during fertilization, is suggested by high and dynamic transcript levels of PA ...
