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 ...

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.

Maize Anther Development Involves Translated Open Reading Frames From 3′ Untranslated Regions

Advanced Science, EarlyView.
This study examined the translation activity across ten stages of maize anther development, integrating transcriptome and small‐peptide data. It linked mutations in translated 3' ORFs to anther sterility, exemplified by Zm00001eb417050_3' ORF (known as APV1). In addition, the data indicated that maize anthers could assimilate CO2 through the stomata in

Aging and longevity in decades‐old genebanked seeds from U.S. endangered plant species: Assessments using survival and RNA integrity assays

American Journal of Botany, EarlyView.
Abstract Premise Seed longevity is critical for successful genebanking, but it is hard to detect or predict. We examined survival of genebanked seeds from species native to the United States to estimate longevity. We tested whether RNA integrity (RIN) can be used to detect aging and predict mortality. Methods Dry seeds from >100 species were stored for

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.

Origin of subgenomes in the circumboreal, allopolyploid, carnivorous plant Drosera anglica

American Journal of Botany, EarlyView.
Abstract Premise The parentage of the widespread allopolyploid Drosera anglica, a member of the carnivorous sundew genus, remains uncertain despite over 100 years of morphological, cytological, and, more recently, molecular study. Methods Using transcriptomic and genomic data from 12 species of Drosera sect. Drosera, including four D.

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,

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

American Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

THE INFLUENCE OF METHOD STORAGE ON FUNCTIONAL PARAMETERS OF POLLEN OF TABLE BEET

Овощи России, 2018
When working with pollen, it is important to keep its functional parameters for some time. To do this, you need to choose the best conditions to preserve pollen germination. The influence of different method of pollen storage of inbred plants of beetroot
