ABSTRACT Melon (Cucumis melo L.) crops are grown in the Semiarid region of Brazil by small, medium, and large farmers, focused on domestic international markets. However, melon is also family farmers using their own seeds, which important germplasm for breeding programs. Samples these seeds were collected stored Active Germplasm Bank Cucurbitaceae from Northeast Region at Brazilian Agricultural...

Abstract A sweet fruit taste of passion is produced by Passiflora ligularis , which adapts in around 1400 masl. Some P. edulis accessions wide elevation adaptation was reported to have a taste. This study aimed examine the morphological characteristics progenies from red- and yellow-rind obtain an adaptive accession low-elevation conditions. total 118 classified as their parents’ rind color sha...

Abstract The pollination of self-incompatible diploid sweet cherry is determined by the S-locus alleles. We resolved S-alleles 50 cultivars grown in Estonia and their incompatibility groups, which were previously unknown for most tested cultivars. used consensus primers SI-19/20, SI-31/32, PaConsI, PaConsII followed allele-specific sequencing to identify S-genotypes. Surprisingly, 48% (24/50) c...

Natural selection acts strongly on the proportional numbers of male and female offspring among the progeny of adults. The equilibrium is often one at which males and females are produced in roughly equal numbers, but under certain ecological and genetic circumstances there may be dramatic population-wide biases, and even in populations with balanced sex ratios, parents are often selected to pro...

Text S1 Two-locus recursion relation Suppose we sample n haplotypes, observing their alleles at each of two loci and obtaining configuration n = (a, b, c). Here c = (cij) is a matrix of the counts of haplotypes for which both alleles were observed; cij is the number of haplotypes with allele i at the first locus and allele j at the second locus. We also allow for the possibility that a haplotyp...

The interaction between myosin subfragment 1 (S1) and actin filaments after the photolysis of P3-1-(2-nitrophenyl)ethyl ester of ATP (caged ATP) was analyzed with a newly developed freezing system using liquid helium. Actin and S1 (100 microM each) formed a ropelike double-helix characteristic of rigor in the presence of 5 mM caged ATP at room temperature. At 15 ms after photolysis, the ropelik...

Helicobacter pylori is a gram-negative rod associated with gastroduodenal pathologies, such as gastritis, peptic ulcer, and gastric adenocarcinoma. Although most H. pylori infections are clinically silent, the organism is associated with substantial morbidity and mortality. It is unknown why the bacteria are able to produce severe disease in some hosts and be innocuous in others. Different viru...

The influence of varying degrees of incompatibility for HL-A antigens on one-way mixed lymphocyte cultures (MLC) has been investigated. Reactions have been compared to a simple expression of HL-A antigens, allele compatibility, and a proposal considering the potential influence of antigen matching in relationship to allele compatibility. As expected, HL-A compatibility was associated with nonst...

The genetic variability of Scots pine was investigated in six populations from Poland representing two maternal populations and their natural and artificial progenies. Thirteen enzyme systems controlled by 2 allozyme loci were analyzed using starch gel electrophoresis. Progeny populations maintained a high and similar level of genetic variation to that observed in the maternal populations. As e...
