A biomechanical model of anther opening reveals the roles of dehydration and secondary thickening.

, 2012
Understanding the processes that underlie pollen release is a prime target for controlling fertility to enable selective breeding and the efficient production of hybrid crops.

Effect of wall-disruption on nutrient composition and in vitro digestion of camellia and lotus bee pollens

Food Science and Human Wellness
The nutrient digestion, absorption and biological activity of bee pollen may be limited due to the complex pollen wall. Here, the effect of superfine grinding technology on the release of nutrients from bee pollen were investigated, and their antioxidant

Persistent symmetry frustration in pollen tubes. [PDF]

PLoS ONE, 2012
Pollen tubes are extremely rapidly growing plant cells whose morphogenesis is determined by spatial gradients in the biochemical composition of the cell wall.

FORMATION OF POLLEN IN THE ANTHER OF LILIUM I. DEVELOPMENT OF THE POLLEN WALL

Acta Botanica Neerlandica, 1980
SUMMARY The ultrastructural changes during the microsporogenesis and gametogenesis in Lilium are studied in relation to the surrounding tissues. In this article the development of the microspore and pollen wall is presented. In relation to the increase in pollen volume the nexine is increased but this process is discontinuous.

Pollen morphology of Curroria, Mondia, Socotranthus and Stomatostemma (Periplocaceae)

Bothalia: African Biodiversity & Conservation, 1993
The pollen morphology of I Planch., O Skeels, Socotranthus Kuntze and Stomatostemma N.E. Br. was studied.All the genera are characterized by pollen grains arranged in tetrads. The arrangement of the grains may be rhomboidal, tetrahedral or decussate. The

Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance

, 2013
Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Analysis of Developing Pollen Grains within Intact Arabidopsis thaliana Anthers by Olympus Two-Photon Laser Scanning Microscopy

Bio-Protocol, 2015
The method consists of imaging developing pollen grains as they form within intact, immature Arabidopsis thaliana anthers. Using two-photon excitation in the infrared wavelength range, the intrinsic fluorescence (autofluorescence) of developing pollen ...

Combined analysis of transcriptome and metabolome reveals that sugar, lipid, and phenylpropane metabolism are essential for male fertility in temperature-induced male sterile rice

Frontiers in Plant Science, 2022
Photoperiod- and thermosensitive genic male sterility (PTGMS) rice is a vital germplasm resource consisting of two-line hybrid rice in which light and temperature strictly control their fertility changes.

Pollen physiology and fertilisation in Vicia Faba L [PDF]

, 1990
In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop.
