Transcriptome analysis provides insight into the regulatory mechanisms underlying pollen germination recovery at normal high ambient temperature in wild banana (Musa itinerans)

Frontiers in Plant Science, 2023
IntroductionCultivated banana are polyploid, with low pollen fertility, and most cultivars are male sterile, which leads to difficulties in banana breeding research. The selection of male parent with excellent resistance and pollen fertility is therefore

A Complex Journey: Cell Wall Remodeling, Interactions, and Integrity During Pollen Tube Growth

Frontiers in Plant Science, 2020
In flowering plants, pollen tubes undergo a journey that starts in the stigma and ends in the ovule with the delivery of the sperm cells to achieve double fertilization.

Arabidopsis Novel Microgametophyte Defective Mutant 1 Is Required for Pollen Viability via Influencing Intine Development in Arabidopsis

Frontiers in Plant Science, 2022
The pollen intine layer is necessary for male fertility in flowering plants. However, the mechanisms behind the developmental regulation of intine formation still remain largely unknown.

Radioautographic visualization of incorporation of lipid precursors into anthers of Muscari comosum (L.) Mili.

Acta Societatis Botanicorum Poloniae, 2015
Incorporation of the following lipid precursors: DL-mevalonic acid-2 3H, 3H palmitic acid and acetic acid-3H sodium salt, into the anther cells of Muscari comosum (L.) Mili. has been investigated.

Pollen characterisation of Maltese honey [PDF]

, 2013
In 2004 and 2005, pollen characterisation of 35 samples of honey collected from the islands of Malta and Gozo, was carried out with the aim to identify the botanical origin of honey produced on these islands.

Dissecting the regulation of pollen tube growth by modelling the interplay of hydrodynamics, cell wall and ion dynamics

Frontiers in Plant Science, 2014
Hydrodynamics, cell wall and ion dynamics are all important properties that regulate pollen tube growth. Currently, the two main pollen tube growth models, the cell wall model and the hydrodynamic model do not appear to be reconcilable.

The ATP-binding cassette (ABC) transporter OsABCG3 is essential for pollen development in rice

Rice, 2018
Background The pollen wall, which protects male gametophyte against various stresses and facilitates pollination, is essential for successful reproduction in flowering plants.

Observations and modelling of birch pollen emission and dispersion from an isolated source [PDF]

, 2014
The occurrence of allergic diseases in western countries increased during the last decades due to greater awareness towards a hygienic lifestyle. The hygiene hypothesis relates the reduced expo- sure to microbial pollution to an underdevelopment of the

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.

Tomato Pollen Wall Development, and the Role of FIN4 in the Formation of the Pollen Intine

, 2021
The cell wall of a mature pollen grain is a highly specialized, multilayered structure. The outer, sporopollenin-based exine protects and supports the pollen grain, while the inner intine, composed primarily of cellulose, is essential for pollen ...
