Research Progress on Calcium Ion in Gametophytic Self-Incompatibility
Journal of Horticultural Research, 2022 Calcium ions are involved in plant self-incompatibility response as important signaling substances in cells. In the sporophytic self-incompatibility response, Ca2+ enters the stigma papilla cells and plays a key role in inhibiting incompatible pollen ...

Apical vesicles: Social networking at the pollen tube tip
Reproduction and Breeding, 2022 Pollen tube growth is asymmetric and highly focused at the tip. It is regarded as an ideal model cell system in plants to study polar cell growth and cell polarity.

Pollen germination and pollen tube growth in ZP maize lines [PDF]
Genetika, 2014 The study was conducted on the in vitro pollen germination at 26?, 28?, 32? and 35?C for 24h of male parental lines, pollen tube growth in vivo in cross pollination of female and male parental lines that make couples in four hybrids: ZP 504 su (? ZPPL 51 ? ? ZPPL 67); ZP 677 (? ZPPL 17 ? ? ZPPL 201); ZP 704 (? ZPPL 109 ? ?

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants
Advanced Science, EarlyView.In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Advanced Science, EarlyView.This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Biologia Plantarum, 2015 Roles for nitric oxide (NO) and reactive oxygen species (ROS) during pollen-tube growth have been well established in angiosperms, but there remains lack of information regarding their potential signalling roles in pollen tubes in gymnosperms.

Arabidopsis COG Complex Subunits COG3 and COG8 Modulate Golgi Morphology, Vesicle Trafficking Homeostasis and Are Essential for Pollen Tube Growth. [PDF]
PLoS Genetics, 2016 Spatially and temporally regulated membrane trafficking events incorporate membrane and cell wall materials into the pollen tube apex and are believed to underlie the rapid pollen tube growth.

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis
Advanced Science, EarlyView.Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Boron toxicity causes multiple effects on Malus domestica pollen tube growth
Frontiers in Plant Science, 2016 Boron is an essential micronutrient for plants. However, boron is also toxic to cells at high concentrations, although the mechanism of this stress is not known.

American Journal of Botany, EarlyView.Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in
