Gametophytic Pollen Tube Guidance: Attractant Peptides, Gametic Controls, and Receptors1[OPEN]
Plant Physiology, 2016 Recent studies have elucidated a molecular framework for the attraction of the pollen tube by synergid cells and the control of attraction by female gametes and sensing by the pollen tube. Pollen tube guidance in flowering plants is a unique and critical

Constrained Nonlinear and Mixed Effects Differential Equation Models for Dynamic Cell Polarity Signaling [PDF]
arXiv, 2016 The key of tip growth in eukaryotes is the polarized distribution on plasma membrane of a particle named ROP1. This distribution is the result of a positive feedback loop, whose mechanism can be described by a Differential Equation parametrized by two meaningful parameters kpf and knf .

Frontiers in Plant Science, 2015 Pollen tubes are an excellent system for studying the cellular dynamics and complex signaling pathways that coordinate polarized tip growth. Although several signaling mechanisms acting in the tip-growing pollen tube have been described, our knowledge on

Pedigree reconstruction for triploid apple cultivars using single nucleotide polymorphism array data
PLANTS, PEOPLE, PLANET, Volume 5, Issue 1, Page 98-111, January 2023., 2023 Many economically, culturally, and historically important apple cultivars are triploids, which have three copies of each chromosome instead of the more typical two copies in diploids. Despite their prevalence and importance, there have been conflicting reports regarding their origin and their ability to beget diploids.

Changes in activity and isozyme patterns of peroxidase and chitinase in kiwifruit pollen
Journal of Applied Botany and Food Quality, 2019 In this study, changes in activity and isozyme patterns of peroxidase (POD) and chitinase in kiwifruit (Actinidia chinensis) pollen were investigated under different storage conditions.

Reconstruction of Past Human land-use from Pollen Data and Anthropogenic land-cover Changes Scenarios [PDF]
arXiv, 2019 Accurate maps of past land cover and human land-use are necessary when studying the impact of anthropogenic land-cover changes on climate. Ideally the maps of past land cover would be separated into naturally occurring vegetation and human induced changes, allowing us to quantify the effect of human land-use on past climate.
