Molecular cloning and transcriptional activity of a new Petunia calreticulin gene involved in pistil transmitting tract maturation, progamic phase, and double fertilization [PDF]

, 2013
Calreticulin (CRT) is a highly conserved and ubiquitously expressed Ca2+-binding protein in multicellular eukaryotes. As an endoplasmic reticulum-resident protein, CRT plays a key role in many cellular processes including Ca2+ storage and release ...

Differences in in vitro pollen germination and pollen tube growth of coconut (Cocos nucifera L.) cultivars in response to high temperature stress

Environmental and Experimental Botany, 2018
Temperature is a primary factor affecting the rate of plant development. Warmer temperatures expected with climate change and the potential for more extreme temperature events will impact plant productivity.

The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity

Cell Reports, 2023
Summary: Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid alkalinization factor4/19-ANXUR1/2-Buddha’s paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2)-complex-mediated signaling pathway is critical to maintain pollen

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]

, 2011
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

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.

Metabolic control of tobacco pollination by sugars and invertases [PDF]

, 2017
Pollination in flowering plants is initiated by germination of pollen grains on stigmas followed by fast growth of pollen tubes representing highly energy-consuming processes.

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.

A compartmental model analysis of integrative and self-regulatory ion dynamics in pollen tube growth. [PDF]

PLoS ONE, 2010
Sexual reproduction in higher plants relies upon the polarised growth of pollen tubes. The growth-site at the pollen tube tip responds to signalling processes to successfully steer the tube to an ovule.

Pollen—pistil interactions during pollen-tube growth

Trends in Plant Science, 1996
Plant sexual reproduction relies on intimate interactions between the pollen and the pistil. These largely extracellular interactions lead to cellular activities within the pollen, enabling the transport of the male gametes by the pollen-tube growth process to the ovules for fertilization.

Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum [PDF]

Electronic Journal of Plant Breeding, 2010
A successful cross fertilization involving two different species implies that a chain of reproductive process takes placeunhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent andmatching gene ...
