determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

In this paper, the compensation of voltage sags and swells using a dynamic restorer (DVR) based on bi-directional AC/AC converter is presented for stabilizing single-phase AC line voltage. The H-bridge with switches without bulk capacitor adopted as power topology proposed system. novel DVR to compensate both sag swell conditions. Additionally, factor closed unity because not required. inner ou...

The formation of viable genetic chimeras in mammals through the transfer of cells between siblings in utero is rare. Using microsatellite DNA markers, we show here that chimerism in marmoset (Callithrix kuhlii) twins is not limited to blood-derived hematopoietic tissues as was previously described. All somatic tissue types sampled were found to be chimeric. Notably, chimerism was demonstrated t...

Mitochondrial biogenesis and function depend upon the interaction of mitochondrial and nuclear genomes. Forward genetic analysis of mitochondrial function presents a challenge in organisms that are obligated to respire. In the S-cytoplasmic male sterility (CMS-S) system of maize, expression of mitochondrial open reading frames (orf355-orf77) conditions collapse of developing haploid pollen. Nuc...

BACKGROUND The H19/Igf2 imprinting control region (ICR) functions as an insulator exclusively in the unmethylated maternal allele, where enhancer-blocking by CTCF protein prevents the interaction between the Igf2 promoter and the distant enhancers. DNA methylation inhibits CTCF binding in the paternal ICR allele. Two copies of the chicken β-globin insulator (ChβGI)(2) are capable of substitutin...

Background & aim: Paternal-fetal attachment develops an emotional relationship between father and his infant which can affect their future interactions. Therefore, the present study aimed to determine the effect of attachment training on paternal-fetal attachment. Methods: This clinical trial was conducted in Karmandan and 22 Bahman health centers in Mashhad in 2015. The participants of the stu...
