GDSL esterase/lipases OsGELP34 and OsGELP110/OsGELP115 are essential for rice pollen development.

Journal of Integrative Plant Biology, 2020
Pollen exine contains complex biopolymers of aliphatic lipids and phenolics. Abnormal development of pollen exine often leads to plant sterility. Molecular mechanisms regulating exine formation have been studied extensively but remain ambiguous.

Hormonome Dynamics During Microgametogenesis in Different Nicotiana Species

Frontiers in Plant Science, 2021
Plant microgametogenesis involves stages leading to the progressive development of unicellular microspores into mature pollen. Despite the active and continuing interest in the study of male reproductive development, little is still known about the ...

Pollen development of Rondeletia odorata (Rubiaceae) [PDF]

American Journal of Botany, 2001
Pollen wall ontogeny of Rondeletia odorata was studied with transmission electron microscopy (TEM) and scanning electron microscopy (SEM) from tetrad stage until maturity. The ontogenetic sequence of wall development in Rondeletia follows, to some extent, the basic scheme in the angiosperms, i.e., development starts centripetally with the pro ...

Toward in vitro fertilization in Brachiaria spp. [PDF]

, 2010
Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Industrial chicory genome gives insights into the molecular timetable of anther development and male sterility

Frontiers in Plant Science, 2023
Industrial chicory (Cichorium intybus var. sativum) is a biannual crop mostly cultivated for extraction of inulin, a fructose polymer used as a dietary fiber.

Molecular cloning and bioinformatic analysis of pollen development related gene BcMF2r from Brassica campestris L. spp. rapifera

浙江大学学报. 农业与生命科学版, 2006
BcMF2r gene, homologous with the BcMF2 gene encoding pollen-specific polygalacturonase of Chinese cabbage-pak-choi, was cloned from turnip (Brassica campestris L. spp. rapifera).

Moisture source and diet affect development and reproduction of Orius thripoborus and Orius naivashae, two predatory anthocorids from southern Africa [PDF]

, 2012
The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around
