to study the genetic relationships among iranian onion landraces and to compare them with those in some foreign cultivars, fifteen microsatellite (ssr) primer pairs were employed. based upon the results of the obtained band pattern, 12 pairs of ssr primers in 18 onion landraces and five foreign cultivars form a polymorphic and scorable pattern. there were two to six alleles with an average of 3...

In this paper we propose a simple fast-search VQ of the LSF’s to be used on top of the split VQ, that is, in each of the sub-vector domains. The main trait of the proposed method is that no suboptimal codebooks are used and there is no further reduction in performance. In each sub-vector domain, a full-size optimally trained codebook, typically of size 1024, is searched using a fastsearch algor...

We discuss the non–autonomous nonlinear partial difference equations belonging to Boll classi?cation of quad graph consistent around cube. show how starting from compatible on a cell we can construct lattice equations, its Backlund transformations and Lax pairs. By carrying out algebraic entropy calculations that H4 trapezoidal H6 families are linearizable in few examples effectively linearize ...

We examine how effectively simple potential functions previously developed can identify compatibilities between sequences and structures of proteins for database searches. The potential function consists of pairwise contact energies, repulsive packing potentials of residues for overly dense arrangement and short-range potentials for secondary structures, all of which were estimated from statist...

Overlapping recombinant clones that encompass the insulin-like growth factor (IGF) I and II genes have been isolated from a human genomic DNA library. Each gene is present once per haploid genome; the IGF-I gene spans greater than 35 kilobase pairs (kbp) and the IGF-II gene is at least 15 kbp. The exon-intron organization of these genes is similar, each having four exons, which is one more than...

In this paper, we establish some common fixed point theorems for two pairs of occasionally weakly compatible single and set-valued maps satisfying a strict contractive condition in a metric space. Our results unify and extend many results existing in the literature including those of Aliouche [3], Bouhadjera [4] and Popa [18]-[23]. Also we establish another common fixed point theorem for four o...

Mutations resistant to compounds that alter the development of Schizophyllum commune (cyclic adenosine monophosphate, caffeine and imidazole) were selected. These mutations defined four genes, car (cAMP resistance), caf-1 and caf-2 (caffeine resistance) and imr (imidazole resistance). The mutations were found to be noncomplementing in certain pairs when tested against each other and against two...
