An ultimate goal of modern biology is to understand how the genetic blueprint of
cells (genotype) determines the structure, function, and behavior of a living organism
(phenotype). At the center of this scientific endeavor is characterizing the biochemical
and cellular roles of proteins, the working molecules of the machinery of life. A
key to understanding of functional proteins is the knowledge of their folded structures
in a cell, as the structures provide the basis for studying proteins’ functions
and functional mechanisms at the molecular level....
The development and rapid implementation of molecular genotyping methods have revolutionized
the possibility for differentiation and classification of microorganisms at the
subspecies level. Investigation of the species diversity is required to determine molecular
relatedness of isolates for epidemiological studies. Methods for molecular epidemiology
of microorganisms must be highly reproducible and provide effective discrimination of
epidemiologically unrelated strains.
Over time, they have developed various characteristics to help them
survive, which leads to plant diversity. It is essential to have regular assessments of
the conservation status of all plant species, in order to prioritize those in need of
conservation action and to provide a measure of the success of actions being taken.
The improvement of cultivated plants considerably depends on the extent of genetic
variability available within the species. Evaluation of different genotypes, varieties,

The birth of livestock genomics 15 years ago was inspired by the human genome initiative
and the potential for capturing both its technologies and massive comparative data
sets for application to livestock species, most of which are mammals. We are currently
reaping the benefits of these efforts, with sequencing projects completed or ongoing in
chickens, cattle, pigs, and horses and valuable mapping resources developed for others
such as sheep and turkeys.

Yellow stem borer has been identified as a major insect pest of deepwater rice, causing severe yield losses. Bt gene(s)
from Bacillus thuringiensis have been proven very effective in pest resistance program. The use of transgenic plants
expressing Bt gene(s) is now occupied effective approach to control insect infestation. We have successfully introduced
a synthetic cryIA(b) gene into embryogenic calli of a deepwater indica rice variety, Vaidehi, by using the biolistic
method of transformation.
The association of TGF b1 polymorphisms and atrial fibrillation (AF) in essential hypertensive (EH) subjects remains unknown. Methods EH subjects with AF (EH+AF+) and sinus rhythm (EH+AF-) were enrolled. The polymorphisms of +869 T ® C at codon 10 and + 915 G ® C at codon 25, were genotyped. The clinical characteristics including serum TGF b1 levels were detected. Results: The GG genotypes of TGF b1 +915 G ® C at codon 25 were more prevalent in subjects from EH+AF+ group than those from EH+AF- group (P = 0.009). The subjects with GG genotype from EH+AF+ group had the...
Populations in Southeast AsiaandSouthChinahave highfrequencies ofa-thalassemia
caused by a-globin gene mutations and/or deletions. This study was designed to find
an efficient and simple diagnostic test for the mutations and deletions. A duplex polymerase
chain reaction (PCR)/denaturing high-pressure liquid chromatography
(DHPLC) was used to detect the mutations and deletions. A blinded study of 110
samples, which included 92 a-thalassemia samples with various genotypes and 18
normal DNA samples, was carried out by the methods.
There is reason to expect strong genetic influences on the risk of developing active pulmonary
tuberculosis (TB) among latently infected individuals. Many of the genome wide linkage and association studies
(GWAS) to date have been conducted on African populations. In order to identify additional targets in genetically
dissimilar populations, and to enhance our understanding of this disease, we performed a multi-stage GWAS in a
Southeast Asian cohort from Indonesia.
Methods: In stage 1, we used the Affymetrix 100 K SNP GeneChip marker set to genotype 259 Indonesian
