“Little is known about the distribution of arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota) in the Turkish arable soils. In this study, we investigated AM fungal phylotype composition in the roots of 13 different plant samples from one site each of the East Black Sea, Mediterranean, and Central Anatolian regions of Turkey. Fifty-seven distinguished operational taxonomic units at 97% nucleotide

sequence identity were recorded among 424 partial sequences of the nuclear ribosomal large subunit (LSU) RNA genes determined. Most of the new sequences were clustered within 10 well-resolved phyloclades of the order Glomerales. About half of the newly determined sequences lacked similar sequences in the public databases. In particular, all sequences from Camellia sinensis collected in the East Black Sea region had only 83-97% Mocetinostat datasheet sequence similarity to known AMF species. The findings suggest that novel and endemic AMF species may exist in Turkish agricultural soils. The AM fungal community composition in the East Black Sea region was relatively simple and completely differed from those in the

other two regions, presumably due to the low soil pH and host specificity. The AM fungal community compositions of the Mediterranean and Central Anatolian samples were broadly similar; however, some sequences related to Rhizophagus were found only in the Mediterranean samples. This reflects the trend that more diverse AM fungal communities are established in the Mediterranean region than the Central Anatolian ACY-738 region.”
“Inheritance studies and molecular mapping identified a single dominant gene Autophagy animal study that conditions seed coat impermeability in soybean PI 594619. High temperatures during seed fill increase the occurrence of soybeans with impermeable seed coat, which is associated with non-uniform and delayed germination and emergence. This can be an issue in soybean production areas with excessively high-temperature environments. The objectives of the present study were to investigate the inheritance of impermeable seed coat under a high-temperature

environment in the midsouthern United States and to map the gene(s) that affect this trait in a germplasm line with impermeable seed coat (PI 594619). Crosses were made between PI 594619 and an accession with permeable seed coat at Stoneville, MS in 2008. The parental lines and the segregating populations from reciprocal crosses were grown in Stoneville in 2009. Ninety-nine F-2:3 families and parents were also grown at Stoneville, MS in 2011. Seeds were assayed for percent impermeable seed coat using the standard germination test. Genetic analysis of the F-2 populations and F-2:3 families indicated that seed coat impermeability in PI 594619 is controlled by a single major gene, with impermeable seed coat being dominant to permeable seed coat.
