UNLABELLED We have developed a program, MPBLAST, that increases the throughput of batch BLASTN searches by multiplexing (concatenating) query sequences and thereby reducing the number of actual database searches performed. Throughput was observed to increase in reciprocal proportion to the component sequence length. For sequencing read-sized queries of 500 bp, an order of magnitude speed-up was...
The subfamily Triatominae, vectors of Chagas disease, comprises 140 species characterized by a highly homogeneous chromosome number. We analyzed the chromosomal distribution and evolution of repeated sequences in Triatominae genomes by Genomic in situ Hybridization using Triatoma delpontei and Triatoma infestans genomic DNAs as probes. Hybridizations were performed on their own chromosomes and ...
In the genus Lilium, plants obtained from crosses, especially between distant relatives, are not always hybrids because embryos can develop as a result of apomixis. These plants constitute genetic material of the maternal parent only. In this study, verification of hybrid status of plants which have been obtained from the crosses 'Marco Polo'xLilium henryi and 'Expression'xL. henryi was perform...
Crossbreeding is a powerful tool for improving productivity and profitability in aquaculture. We conducted a pilot study of an artificial cross between two important cultivated scallops in China, Chlamys farreri and Mimachlamys nobilis, to test the feasibility of interspecific hybridization. Reciprocal hybridization experiments were performed using a single-pair mating strategy (M. nobilis ♀ × ...
Gibbs’s inequality states that the differential entropy of a random variable with probability density function (pdf) f is less than or equal to its cross entropy with any other pdf g defined on the same alphabet, i.e., h(X) ≤ −E[log g(X)]. Using this inequality with a cleverly chosen g, we derive a lower bound on the smallest output entropy that can be achieved by quantizing a d-dimensional sou...

to remove unfavorable traits of new cereal tritipyrum (2n=6x=42, aabbebeb), various crosses between primary tritipyrum lines (female) with iranian bread wheat varieties (2n=6x=42, aabbdd) was performed and a f2 selfing population consisted of 1810 possible secondary tritipyrum seeds (2n=6x=42, aabbd(0-14) eb(0-14)) were produced. the chromosome constitution and homology index of 11 plants of th...
مطالعه ساختار کروموزومی ژنوتیپ‌های تریتی‌پایرم ثانویه (2F) با روش دورگه‌سازی DNA ژنومی در محل (GISH)
به‌منظور حذف صفات نامطلوب غله جدید تریتی‌پایرم (AABBEbEb، 42=x6=n2) تلاقی‌های گسترده‌ای بین لاین‌های این غله (پایه مادری) و ارقام گندم نان ایرانی (پایه پدری) انجام و از خودگشنی نتاج 1F در نسل دوم تعداد 1810 بذر احتمالی تریتی‌پایرم ثانویه ('(14-0) D'(14-0)AABBEb، 42=x6=n2=2F) تولید شد. تعادل کروموزومی و شاخص همولوژی در 11 گیاه احتمالی تریتی‌پایرم ثانویه (2F) با دورگه‌سازی DNA ژنومی علف شور ساحل ...
