Chromosome segregation in plant meiosis [PDF]

open access: yesFrontiers in Plant Science, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating aneuploid or polyploid progeny, respectively.

Genome Wide Association Mapping of Seedling and Adult Plant Resistance to Barley Stripe Rust (Puccinia striiformis f. sp. hordei) in India

open access: yesFrontiers in Plant Science, 2018
Barley stripe rust is caused by Puccinia striiformis f.sp. hordei, (Psh), occurs worldwide, and is a major disease in South Asia. The aim of this work was to identify and estimate effects of loci underlying quantitative resistance to rust at seedling and

New introgressive forms of cultivated barley obtained on the basis of interspecific hybrids Hordeum vulgare L. × Hordeum bulbosum L.

open access: yesБиотехнология и селекция растений, 2021
Background. The use of alien genetic material of bulbous barley Hordeum bulbosum L. to increase the diversity of cultivated barley Hordeum vulgare L. is an important task, since H. bulbosum is characterized by a number of valuable traits. One of the ways

Genetic mapping and comparative expression analysis of transcription factors in cotton.

open access: yesPLoS ONE, 2015
Transcription factors (TFs) play an important role in the regulation of plant growth and development. The study of the structure and function of TFs represents a research frontier in plant molecular biology.

Using intervarietal substitution lines for the identification of wheat chromosomes involved in early responses to water-deficit stress.

open access: yesPLoS ONE, 2019
Water deficit induces reactive oxygen species (ROS) overproduction, which in turn inhibits plant growth and development. High concentrations of ROS disrupt the osmotic balance in plant cells and alter membrane integrity.

Holocentric chromosomes.

open access: yesPLoS Genetics, 2020
Holocentric chromosomes possess multiple kinetochores along their length rather than the single centromere typical of other chromosomes [1]. They have been described for the first time in cytogenetic experiments dating from 1935 and, since this first ...

Genomic rearrangements generate hypervariable mini-chromosomes in host-specific isolates of the blast fungus.

open access: yesPLoS Genetics, 2021
Supernumerary mini-chromosomes-a unique type of genomic structural variation-have been implicated in the emergence of virulence traits in plant pathogenic fungi.

Germplasm Architecture Revealed through Chromosomal Effects for Quantitative Traits in Maize

open access: yesThe Plant Genome, 2016
Germplasm architecture refers to how favorable alleles for a given trait are distributed across the genome in a germplasm collection. Our objective was to assess germplasm architecture for quantitative traits among US maize ( L.) inbreds.

High density genetic mapping of Fusarium head blight resistance QTL in tetraploid wheat. [PDF]

open access: yesPLoS ONE, 2018
Breeding for Fusarium head blight (FHB) resistance in durum wheat is complicated by the quantitative trait expression and narrow genetic diversity of available resources.

Chromosome-centric approaches in crop genomics: Focus on Mendel's pea plant

open access: yesCzech Journal of Genetics and Plant Breeding, 2022
Gregor Mendel laid foundations of genetics after his experiments in pea plant hybridization. The choice of pea (Pisum sativum L.) and its seven morphological characters as a model system was fortuitous and enabled the fundamental discoveries ...
