ECS1 and ECS2 suppress polyspermy and the formation of haploid plants by promoting double fertilization [PDF]

open access: yeseLife, 2023
The current pace of crop plant optimization is insufficient to meet future demands and there is an urgent need for novel breeding strategies. It was previously shown that plants tolerate the generation of triparental polyspermy-derived plants and that ...

Three Cell Fusions during Double Fertilization [PDF]

open access: yesCell, 2015
Fertilization of both egg and central cell is a major distinguishing feature of flowering plants. Now, Maruyama et al. report a third cell fusion event between the persistent synergid and the fertilized central cell shortly after double fertilization in Arabidopsis. This causes rapid dilution of pollen tube attractant(s), preventing polytubey.

Long-Term Manure Amendment Sustains Black Soil Biodiversity by Mitigating Acidification Induced by Chemical N Fertilization

open access: yesMicroorganisms, 2022
The long-term use of chemical N fertilization may have a negative impact upon soil fertility and quality. On the contrary, organic fertilization is considered a sustainable development agricultural strategy.

Effects of Fertilization and Ridge Furrow Planting Patterns on Soil Microbial Communities, Nutrient Dynamics, and Maize Productivity [PDF]

open access: yesBiology
This study investigated how fertilization regimes and ridge furrow planting patterns influence the soil nutrient conditions and microbial taxonomic composition and function in the rhizosphere of spring maize in Northeast China.

MOLECULAR ANALYSIS OF DOUBLE FERTILIZATION PROCESS IN ARABIDOPSIS [PDF]

open access: yes, 2013
Fertilization and seed formation are key events in the life cycle of flowering plants. The seed represents an elaborated functional unit, whose main purpose is to propagate the plant's offspring. The first step in seed development is the formation of ovules and subsequently the achievement of a successful double fertilization process.

Central Cell in Flowering Plants: Specification, Signaling, and Evolution

open access: yesFrontiers in Plant Science, 2020
During the reproduction of animals and lower plants, one sperm cell usually outcompetes the rivals to fertilize a single egg cell. But in flowering plants, two sperm cells fertilize the two adjacent dimorphic female gametes, the egg and central cell ...

SOC sequestration affected by fertilization in rice-based cropping systems over the last four decades [PDF]

open access: yes, 2023
Enhancing soil organic carbon (SOC) stocks through fertilization and crop rotation will contribute to sustaining crop productivity and mitigating global warming.

Poles Apart: Monosporic, Bisporic, and Tetrasporic Embryo Sacs Revisited

open access: yesFrontiers in Ecology and Evolution, 2020
Bisporic embryo sacs contain nuclei derived from two members of a megaspore tetrad whereas tetrasporic embryo sacs contain nuclei derived from all four members of a tetrad.

Simple Whole-Mount Staining Protocol of F-Actin for Studies of the Female Gametophyte in Agavoideae and Other Crassinucellate Ovules

open access: yesFrontiers in Plant Science, 2020
During plant sexual reproduction, F-actin takes part in the elongation of the pollen tube and the movement of sperm cells along with it. Moreover, F-actin is involved in the transport of sperm cells throughout the embryo sac when double fertilization ...

Double fertilization in Drosophila melanogaster [PDF]

open access: yesHereditas, 2008
In an inbred line of Drosophila melanogaster with marker genes on the sex-chromosomes as well as on one of the autosomes, it was shown that double fertilization (two sperms fertilizing one egg) is a reality and that gynandromorphic flies can be the result of double fertilization as well as of X-chromosome loss. In this inbred line it happens with about
