A study on pollen characteristics of bisexual and functionally male flowers in pomegranate [PDF]

Guoshu xuebao
[Objective] Pollen is the genetic carrier of the male parent in plant sexual reproduction. Pollen germination on the stigma of female flower and fertilization is the prerequisite for successful reproduction for plants.

Chloride fluxes in lily pollen tubes: a critical reevaluation

, 2004
Microelectrodes, made from a Cl?-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl?

A Virus‐Inducible E3–RLCK–MADS Module Coordinates Suppression of Plant Immunity and Fertility in Rice

Advanced Science, EarlyView.
ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

Advanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Pollen thermotolerance of a widespread plant, Lotus corniculatus, in response to climate warming: possible local adaptation of populations from different elevations [PDF]

PeerJ
One of the most vulnerable phases in the plant life cycle is sexual reproduction, which depends on effective pollen transfer, but also on the thermotolerance of pollen grains.

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 ...

Native grass breeding: Priority needs and strategic approaches

Grassland Research, EarlyView.
The key needs and breeding strategies of native grass. Abstract Native grasses possess extensive ecological adaptability, such as cold, drought, and salt tolerance, and tolerance to poor soil conditions. They play a crucial role in ensuring food security and ecological security.

Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat

HortScience, 2023
The increasing intensity and frequency of extreme heat events threaten crop productivity globally. Certain phases of plant reproduction necessary for fertilization are highly sensitive to extreme heat, particularly during pollen development, germination,
