Channa punctatus is a freshwater fish belonging to family Ophiocephalidae. This fish is available in almost all over the country. In present communication molecular study of COI region of mitochondrial gene was done to find out intraspecific differences in genome of Channa punctatus habitating in different states of India having variable environmental conditions. Result showed minor variations ...

The structural differentiation of rostrum in male and female adults of rice weevil, Sitophilus oryzae was examined under the light and electron microscopes to understand its functional potential in infestation/ovipositional tactics. The microscopic observation revealed that, the length of the rostrum was remarkably longer and thinner for females than in males. This adaptation in females is high...

Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...

Introduction Reelin gene (RELN) codes a large extracellular matrix glycoprotein with serine protease activity and is implicated in the modulation of neuronal signaling, synaptic transmission and plasticity. The reelin plays a fundamental and pivotal role in the development of laminar structures and may be one of the loci contributing to the positive linkage between chromosome 7q and autistic di...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract Aims: The study goals were to determine the relationship between faecal indicator bacteria (FIB), the HF183 marker and land use, and the phylogenetic diversity of HF183 marker sequences in a tropical urban watershed. Methods and Results: Total coliforms, Escherichia co...

A system is proposed here for assigning a derived P-marker to a given transformed sentence and obtaining the corresponding base P-marker at the same time. Rules of analytical phrase-structure grammar for such a system have associated with them i~formation pertaining to the transformational histories of their own derivation. When a phrase-structure analysis of the sentence is obtained, the set o...

Introduction Sexual problems and dysfunctions are relatively common experiences which significantly impact on the perceived quality of life; sexual dysfunction has been shown to be associated with anxiety, depression, interpersonal difficulties and overall negative well-being. Recent research has shown that sexual health can be indicative of overall health, for example; erectile dysfunction has...

One concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. Molecular markers are an important element for efficient and effective determination of genetic variation. The present work was carried out to assess the genetic uniformity of transgenic cottons (Bt and chitinase lines), using RAPD, ISSR molecular markers and SDS-PAGE an...

Background:Anopheles maculipennis complex species is considered as one of the most important species complexes with 12 species and significant role in the transmission of important diseases such as malaria, lymphatic filariasis and multiple Arboviral infections. The aim of the present study was to analyze Internal Transcribd Spacer (ITS) 2 fragment among Anopheles ...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...
