drought sensitivity is considered as a major concern for chickpea (c. arietinum) seed production. determination of drought adaptation mechanisms is an essential constituent of this crop breeding programs. with this purpose, the present research was conducted to distinguish the molecular basis of chickpea drought tolerance using cdna-aflp approach. the expression profile was compared between dro...

The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...

MOTIVATION In genetic studies of complex diseases, haplotypes provide more information than genotypes. However, haplotyping is much more difficult than genotyping using biological techniques. Therefore effective computational techniques have been in demand. The individual haplotyping problem is the computational problem of inducing a pair of haplotypes from an individual's aligned SNP fragments...

Finding longest common subsequence (LCS) is a common problem in Biology informatics. The problem is defined as follows: Given two strings X=x1x2...xm and Y=y1y2...yn, find a common subsequence L=l1l2...lp of X and Y such that p is maximized. In this paper, we discuss a variation of the LCS problem – LCS from fragments problem defined as follows: Given two strings X and Y and a set M of fragment...

Radiation hybrid mapping is a somatic cell technique for ordering genetic loci along a chromosome and estimating physical distances between adjacent loci. This paper presents a model of fragment generation and retention for data involving two or more copies of the chromosome of interest per clone. Such polyploid data can be generated by initially irradiating normal diploid cells or by pooling h...

Phaseolin is the major seed storage protein of common bean (Phaseolus vulgaris L.). It is encoded by a small multigene family of 6-9 genes that are clustered in a single complex locus (Phs). We have constructed a long-range restriction map of the phaseolin genomic region, including the Phs locus and two flanking marker loci, D1861 and Bng060. Using a combination of high molecular weight DNA iso...

In this paper we investigate rst order common knowledge logics; i.e., modal epistemic logics based on rst order logic with common knowledge operators. It is shown that even rather weak fragments of rst order common knowledge logics are not recursively axiomatizable. This applies, for example, to fragments which allow to reason about names only; that is to say, fragments the rst order part of wh...

The following research assesses the possibility to predict maximum emission wavelenghts of organic compounds based on quantum chemistry properties compounds’ fragments. predictions are compared with molecular descriptors and fingerprints widely applied in cheminformatics. Machine learning was an effort establish relationship between structures their optical properties. Multilinear, gradient boo...
