Terverticillate penicillia were important colonists of the underground seed caches and the external cheek pouches of the banner-tailed kangaroo rat (Dipodomys spectabilis) from the North American desert. Two taxa representing the dominant Penicillium populations are described as new varieties of well-known ubiquitous species. Penicillium chrysogenum var. dipodomyis var.nov. produces the antibiotic penicillin but does not produce mycotoxins (PR-toxin and roquefortine C) known from P. chrysogenum. The new variety is further distinguished by having rough-walled stipes. Penicillium aurantiogriseum var. neoechinulatum var.nov. isolates produce penicillic acid, viridicatin, and cyclopenin, metabolites with antibiotic properties, but not the potent nephrotoxins xanthomegnin and viomellein or tremorgenic mycotoxins (e.g., penitrem A). The variety is also distinguished by conspicuously rough-walled conidia. Three additional new varieties which do not produce mycotoxins normally associated with their species are also reported: P. griseofulvum var. dipodomyicola var.nov. produced the antibiotically active compounds patulin and griseofulvin but not cyclopiazonic acid and roquefortine C; P. glandicola var. mononematosa var.nov. and P. glandicola var. confertum var.nov. did not produce roquefortine C, penitrem A, or patulin. Infrequently isolated strains of the species P. viridicatum and P. griseofulvum duplicated the mycotoxin profiles of the cultures ex type. It is suggested that the evolution of seed-caching behaviour in D. spectabilis may have guided the selection of less-toxic terverticillate penicillia as colonists in rodent seed caches.

The article presents the results of breeding work for the creation of new high-yielding varieties of bitter-aromatic hops with a high content of alpha-acids carried out in 2004-2020 in the Chuvash Republic on gray forest soils. The work was done by individual clonal selection of the best hop plants from the collection nursery. Seven high-yielding breeding numbers with a high alpha-acid content were selected from the collection nursery. After passing through all the stages of study in each of the appropriate nurseries from seven numbers, two clones were selected to create new varieties. Data were obtained on the parameters of the initial clonal breeding material, depending on weather conditions and the age of plantings. The selected clones (1-17 bitter-aromatic type and 6-26 bitter type) correspond to the specified indicators: collection of raw hops is not less than 4.0 kg from a bush, the duration of the growing period is 100-120 days, the content of alpha acids is not less than 5.0 %. Documentation on clone 1-17 was sent to the State Variety Commission for registration of a new variety Salampi. The variety is characterized by stable performance and quality indicators. The productivity of the variety is 30.0 c/ha (4.0 kg/bush) with a content of alphaacids of 9.3 %. The Podvyazny standard variety has 26.4 c/ha (3.5 kg/bush), the content of alpha-acids is 8.8 %. Testing of clone 6-26 will be continued to obtain complete and objective data.

The article presents the results of the analysis of the biochemical composition of selected in the competitive variety testing of new varieties and promising lines of spring barley, studied on the experimental field ISA-branch of FGBNU FNAC VIM in 2016-2018. Result of research in different years of water availability among the rooms was allocated a group of high-protein barley with improved feed value: 4 varieties, 2 of which are on the state variety testing, and 2 promising lines. The range of variation of protein content in the grain of the selected samples varied from 13.1 to 14.5 %, lysine – from 0.48 to 0.52 %, weight of 1000 grains-from 48.0 to 53.5 g. According to the data obtained the highest value of protein in grain was observed in krupnosortnogo varieties Zlatoyar (GSI), amounting on average for 14.5 %. The increase was equal to 1.1% in relation to the control variety Yaromir. With an average yield of 6.52 t/ha in the years of research grade Accounting have provided protein per hectare in the amount of 0,94 t/ha. A new variety Sudar´ (GSI) and breeding line 149/4-12 h 788 and 129/1-14 h 907 this indicator has been less productive, however, exceeded the grade Yaromir 0.10 to 0.16 t/ha. Given the higher productivity of new promising varieties and breeding lines, the collection of lysine per unit area they have 12.7, 30.8 per cent was higher than that of the Promej class and 10.6-23.6% more than in the variety Yaromir, which indicates their high biological value. Selected hulless line 1137 h is also an encouraging source of protein and other nutrients of plant origin. The selected lines and new varieties, regardless of weather conditions, were able to ensure the production of high-protein and sources' grain for feed purposes, while maintaining productivity.

SUMUT Bank is one of the Banks in Indonesia with the name of the company PT. Regional Development Bank of North Sumatra. The North Sumatra Bank has branches in each region in North Sumatra both in the district and in the sub-district, and each of these branches is led by a branch leader or branch head. The head of this branch is responsible for the reversal of the Bank being led. The best and most accomplished branch heads deserve more and more awards. The selection of the best branch heads is selected transparently and structured in the hope that it can be a motivation for all branch heads to be able to further improve the quality and service of the Bank they lead. Making the best branch head selection done manually will take a long time and tends to be less transparent and structured. One solution so that the implementation of the selection can be carried out easily and quickly, it requires a Decision Support System that can provide consistency of assessment. In this study the method used is the VIKOR method (Visekriterijumsko Kompromisno Rangiranje). This method makes cracking on alternatives based on criteria that have been determined with an ideal compromise solution or the best solution, so that this system can later be beneficial for the SUMUT Bank to get the title in determining the best branch head.Keywords: Decision Support System, North Sumatra Bank, Branch Head, Vikor

Exploring and exploiting variety by environment (V × E) interaction is one of the major challenges facing plant breeders. In paper I of this series, we presented an approach to modelling V × E interaction in the analysis of complex multi-environment trials using factor analytic models. In this paper, we develop a range of statistical tools which explore V × E interaction in this context. These tools include graphical displays such as heat-maps of genetic correlation matrices as well as so-called E-scaled uniplots that are a more informative alternative to the classical biplot for large plant breeding multi-environment trials. We also present a new approach to prediction for multi-environment trials that include pedigree information. This approach allows meaningful selection indices to be formed either for potential new varieties or potential parents.

Historically, many population genetics studies have utilized microsatellite markers sampled at random from the genome and presumed to be selectively neutral. Recent studies, however, have shown that microsatellites can occur in transcribed regions, where they are more likely to be under selection. In this study, we mined microsatellites from transcriptomes generated by 454-pyrosequencing for three vertebrate species: lake sturgeon (Acipenser fulvescens), tiger salamander (Ambystoma tigrinum), and kangaroo rat (Dipodomys spectabilis). We evaluated (i) the occurrence of microsatellites across species; (ii) whether particular gene ontology terms were over-represented in genes that contained microsatellites; (iii) whether repeat motifs were located in untranslated regions or coding sequences of genes; and (iv) in silico polymorphism. Microsatellites were less common in tiger salamanders than in either lake sturgeon or kangaroo rats. Across libraries, trinucleotides were found more frequently than any other motif type, presumably because they do not cause frameshift mutations. By evaluating variation across reads assembled to a given contig, we were able to identify repeat motifs likely to be polymorphic. Our study represents one of the first comparative data sets on the distribution of vertebrate microsatellites within expressed genes. Our results reinforce the idea that microsatellites do not always occur in noncoding DNA, but commonly occur in expressed genes.
