the possibility of occurrence of some rearrangements inside and or around coxii and atp6 genes and their relationship with male sterility in rice lines having wild abortive (wa)  cytoplasm was studied. two sterile (ir58025a and ir62829a) and two maintainer lines (ir58025b and ir62829b) were used. radioactive southern blotting was employed to carry out the experiments. the hybridization of coxii...

Soybean dwarf virus (SbDV), a Luteoviridae family member, causes dwarfing, yellowing and sterility of soybean (Glycine max), leading to one of the most serious problems in soybean production in northern Japan. Previous studies revealed that the Indonesian soybean cultivar 'Wilis' is resistant to SbDV and that the resistance can be introduced into Japanese cultivars. A major QTL for SbDV resista...

BACKGROUND Replication-independent active/enzymatic demethylation may be an important process in the functioning of somatic cells. The most plausible mechanisms of active 5-methylcytosine demethylation, leading to activation of previously silenced genes, involve ten-eleven translocation (TET) proteins that participate in oxidation of 5-methylcytosine to 5-hydroxymethylcytosine which can be furt...

As a common cause of reproductive isolation in diverse taxa, hybrid incompatibilities are fundamentally important to speciation. A key question is which evolutionary forces drive the initial substitutions within species that lead to hybrid dysfunction. Previously, we discovered a simple genetic incompatibility that causes nearly complete male sterility and partial female sterility in hybrids be...

We have been analyzing genes for reproductive isolation by replacing Drosophila melanogaster genes with homologs from Drosophila simulans by interspecific backcrossing. Among the introgressions established, we found that a segment of the left arm of chromosome 2, Int(2L)S, carried recessive genes for hybrid sterility and inviability. That nuclear pore protein 160 (Nup160) in the introgression r...

An experiment on the effect of different nitrogen levels yield and attributes rice varieties was conducted in Kanchanpur, Nepal, from March 2021 to July 2021. The laid randomized complete block design with two factors: varieties, each factor having three (Nitrogen: 60kg/ha, 120kg/ha, 180kg/ha varieties: Hardinath 1, Hardianth 3 Chaite 5) resulting nine treatment combinations. Rice seeds were so...

Male sterility derived from Satsuma mandarin (Citrus unshiu) has been used in Japanese citrus breeding programs to obtain seedless cultivars, which is a desirable trait for consumers. Male sterility has often been evaluated by anther development or pollen fertility; however, the inheritance and heritability of male sterility derived from Satsuma is poorly understood. In this study, we investiga...

Our Journal's tendency towards the real world in applied linguistics and literary studies should have significant epistemological and methodological consequences in researching the fields. The interest in the real world makes the problems we may have in our everyday lives our 'points of departure' in research. According to my experience of research in our universities throughout their history, ...

First, this study aims to ascertain if truly the generic timolol eye drops circulating in Abuja and it environ are interchangeable. Secondly, we explore their cost effectiveness naira based on dispensing position. Using official guidelines, assessed seven ophthalmic preparations for organoleptic, pH, viscosity, sterility, assay test. After this, they were tested vertical (90 ⁰) horizontal (30 p...
