Heterosis and the nature and combining ability was studied in 7 × 7 diallel cross in maize for grain yield and yield contributing characters. The significant estimates of GCA and SCA variances suggested the importance of both additive and non-additive gene actions for the expression studied traits. Preponnderance of additive gene action was noticed for ear diameter and 1000-kernel weight and th...

Abstract This research explores the compactness of apple varieties and forms with different types crown. Orchards on semi-vigorous rootstocks density high planting systems are cost-effective in modern horticulture. For making such gardens, it is necessary to have trees special compact crown shape. They ensure high-quality fruits production, meeting requirements world standards. To date most per...

CD8+ T cells induced by Plasmodium yoelii sporozoites develop into protective memory cells without undergoing changes in interleukin-7 receptor alpha (IL-7Ralpha) expression, differing from the development of memory CD8+ T cells against viruses, which is associated with enhanced IL-7Ralpha expression. This suggests a microbe-dependent diversity in the signals determining the development of memo...

In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents wi...

Removal of the mRNA 5' cap is an important step in the regulation of mRNA stability. mRNAs are degraded by at least two distinct exonucleolytic decay pathways, one from the 5' end, and the second from the 3' end. Two major cellular decapping enzymes have been identified, and each primarily functions in one of the two decay pathways. The Dcp2 decapping enzyme utilizes capped mRNA as substrate an...

Testosterone (250 microM), 7-ethoxycoumarin (25 microM), and 1-chloro-2,4-dinitrobenzene (CDNB, 50 microM) were used as substrates to compare phase I and II metabolism in rat precision-cut liver slices and rat hepatocytes. Overall clearance to metabolites was significantly greater in hepatocytes for testosterone (1.9- to 16.9-fold), 7-ethoxycoumarin (O-deethylation, 14.8-fold; glucuronidation, ...

ABSTRACT Pepper plants can be used as ornamental ones due to the contrasting traits of plants, flowers, and especially fruits. This variability exploited in genetic improvement programs aiming at identifying superior genotypes obtaining hybrids. work aimed select parental hybrid individuals through diallel analysis for fruit Capsicum annuum. Seven pepper were crossed, eleven fruit-related quant...

The antimicrobial susceptibility profiles of 76 Streptococcus agalactiae (Group B Streptococci [GBS]) isolates from vaginal specimens of pregnant women near term were correlated to their genotypes generated by Random Amplified Polymorphic DNA analysis and their virulence factors encoding genes cylE, lmb, scpB, rib, and bca by PCR. Based on the distribution of the susceptibility patterns, six pr...

Parametric methods for estimating the phenotypic stability of «Agricultural crops require compliance with normal distribution data and a balanced design experiment, which is rarely achievable under conditions current breeding work. This also relevant technology developing in vitro regenerants resistance to edaphic stress factors, when volume seed material limited. The purpose study was comparat...
