The Insights into Mitochondrial Genomes of Sunflowers.

The significant difference in the mtDNA size and structure with simultaneous slow evolving genes makes the mitochondrial genome paradoxical among all three DNA carriers in the plant cell. Such features make mitochondrial genome investigations of particular interest. The genus is a diverse taxonomic group, including at least two economically valuable species-common sunflower () and Jerusalem artichoke ().

Organization Features of the Mitochondrial Genome of Sunflower ( L.) with ANN2-Type Male-Sterile Cytoplasm.

This study provides insights into the flexibility of the mitochondrial genome in sunflower ( L.) as well as into the causes of ANN2-type cytoplasmic male sterility (CMS). assembly of the mitochondrial genome of male-sterile HA89(ANN2) sunflower line was performed using high-throughput sequencing technologies.

Characterization of the mitochondrial genome of the MAX1 type of cytoplasmic male-sterile sunflower.

Background: More than 70 cytoplasmic male sterility (CMS) types have been identified in Helianthus, but only for less than half of them, research of mitochondrial organization has been conducted. Moreover, complete mitochondrion sequences have only been published for two CMS sources - PET1 and PET2. It has been demonstrated that other sunflower CMS sources like MAX1, significantly differ from the PET1 and PET2 types.

Probiotic Intake Increases the Expression of Vitellogenin Genes in Laying Hens.

A promising approach for slowing down the rate of reproductive aging is the use of probiotic bacteria as a feed additive. In the current study was investigated the influence of the intake of a potential probiotic on the follicle content and expression of vitellogenin genes (vtg1, vtg2, vtg3) in aged hens. RNA was isolated from liver samples collected from 570-day-old laying hens and gene expression levels were measured using RT-PCR.

Mitochondrial genomes organization in alloplasmic lines of sunflower ( L.) with various types of cytoplasmic male sterility.

Background: Cytoplasmic male sterility (CMS) is a common phenotype in higher plants, that is often associated with rearrangements in mitochondrial DNA (mtDNA), and is widely used to produce hybrid seeds in a variety of valuable crop species. Investigation of the CMS phenomenon promotes understanding of fundamental issues of nuclear-cytoplasmic interactions in the ontogeny of higher plants. In the present study, we analyzed the structural changes in mitochondrial genomes of three alloplasmic lines of sunflower ( L.

The Impact of Bacillus subtilis KATMIRA1933 Supplementation on Telomere Length and Mitochondrial DNA Damage of Laying Hens.

In the current study, we performed in vivo investigation of probiotic intake influence on nuclear and mitochondrial DNA damage of hens, using quantitative PCR techniques. The probiotic supplementation to the diet of Hisex Brown hens had no significant effect on the rate of telomere shortening. After prolonged probiotic intake (225 and 445 days), the 18-21% decrease in the mtDNA lesions was detected.

Bacillus Probiotic Supplementations Improve Laying Performance, Egg Quality, Hatching of Laying Hens, and Sperm Quality of Roosters.

The study aims at elucidating the effect of bacilli probiotic preparations on the physiology of laying hens and roosters. Probiotic formulations were prepared as soybean products fermented by Bacillus subtilis KATMIRA1933 and Bacillus amyloliquefaciens B-1895. In this study, groups of male and female chickens were used.
