Investigating the Origin and Evolution of Polyploid L. Karyotype by Comparative Cytogenomic Methods.

L. is a wild polyploid relative of the agriculturally important red clover that possesses traits promising for breeding purposes. To date, also remains the only clover species with which agriculturally important red clover has successfully been hybridized.

Genes Associated with Biological Nitrogen Fixation Efficiency Identified Using RNA Sequencing in Red Clover ( L.).

Commonly studied in the context of legume-rhizobia symbiosis, biological nitrogen fixation (BNF) is a key component of the nitrogen cycle in nature. Despite its potential in plant breeding and many years of research, information is still lacking as to the regulation of hundreds of genes connected with plant-bacteria interaction, nodulation, and nitrogen fixation. Here, we compared root nodule transcriptomes of red clover ( L.

Chromosome and Genome Diversity in the Genus (Fabaceae).

L. is an economically important genus that is characterized by variable karyotypes relating to its ploidy level and basic chromosome numbers. The advent of genomic resources combined with molecular cytogenetics provides an opportunity to develop our understanding of plant genomes in general.

Variation in Ribosomal DNA in the Genus (Fabaceae).

The genus L. is characterized by basic chromosome numbers 8, 7, 6, and 5. We conducted a genus-wide study of ribosomal DNA (rDNA) structure variability in diploids and polyploids to gain insight into evolutionary history.

Allelic Variants for Candidate Nitrogen Fixation Genes Revealed by Sequencing in Red Clover ( L.).

Plant-rhizobia symbiosis can activate key genes involved in regulating nodulation associated with biological nitrogen fixation (BNF). Although the general molecular basis of the BNF process is frequently studied, little is known about its intraspecific variability and the characteristics of its allelic variants. This study's main goals were to describe phenotypic and genotypic variation in the context of nitrogen fixation in red clover ( L.

Red Clover () and Zigzag Clover () - A Picture of Genomic Similarities and Differences.

The genus clover ( sp.) is one of the most economically important genera in the Fabaceae family. More than 10 species are grown as manure plants or forage legumes.

Gene Classification and Mining of Molecular Markers Useful in Red Clover () Breeding.

Red clover () is an important forage plant worldwide. This study was directed to broadening current knowledge of red clover's coding regions and enhancing its utilization in practice by specific reanalysis of previously published assembly. A total of 42,996 genes were characterized using Illumina paired-end sequencing after manual revision of Blast2GO annotation.

Genome assembly and annotation for red clover (Trifolium pratense; Fabaceae).

Premise Of The Study: Red clover (Trifolium pratense) is an important forage plant from the legume family with great importance in agronomy and livestock nourishment. Nevertheless, assembling its medium-sized genome presents a challenge, given current hardware and software possibilities. Next-generation sequencing technologies enable us to generate large amounts of sequence data at low cost.

Isolation and characterization of a novel semi-lethal Arabidopsis thaliana mutant of gene for pentatricopeptide (PPR) repeat-containing protein.

A novel Arabidopsis thaliana mutant of one member of the pentatricopeptide repeat (PPR) gene family has been identified among T-DNA insertion lines. Tagging of the At1g53330 gene caused the appearance of a semi-lethal mutation with a complex phenotypic expression from embryo lethality associated with the abnormal pattern of cell division during globular to heart transition to fertile plants with just subtle phenotypic changes. The PPR protein At1g53330.

New embryo lethals in Arabidopsis thaliana: basic genetic and morphological study.

Six different mutations with defects in immature seed development have been identified during screening of a T-DNA collection of Arabidopsis thaliana. The mutations were confirmed to be monogenic and recessive-lethal by genetic analysis. Mutant embryos were blocked in certain steps in the process necessary for embryo viability and development, and therefore they belong to the embryo-lethal class of mutants.
