Plant Chromosome-Specific Probes by Microdissection of a Single Chromosome: Is That a Reality?

Frontiers in Plant Science, 2020
Painting plant chromosomes through chromosomal in situ suppression (CISS) hybridization has long been considered impracticable. Seeking to build specific and complex probes from a single microdissected chromosome, we employed human chromosomes as models ...

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

Frontiers 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.

Биотехнология 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

Asymmetric somatic plant hybridization : status and applications [PDF]

, 2013
To create asymmetric somatic hybrids, the genome of the so-called donor protoplast is fragmented prior to protoplast fusion. As a result, only a limited amount of the donor genome is transferred to the fusion product.

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]

, 2015
The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

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

PLoS 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.

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

PLoS 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.

B chromosomes in plants [PDF]

New Phytologist, 1995
summaryThis review of supernumerary B chromosome systems in flowering plants deals mainly with work published in the last 15 yr, hut also includes older material which has not hitherto been presented systematically. The term B chromosome (B) is defined, and there is an introductory overview dealing with general characteristics and the significance of ...

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

PLoS 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.

PLoS 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 ...
