PCR-based DNA fingerprinting indicates host-related genetic variation in the nematophagous fungus Pochonia chlamydosporia.

The mitosporic fungus Pochonia chlamydosporia is a potential biocontrol agent for cyst (Heterodera spp. and Globodera spp.) and root knot (Meloidogyne spp.) nematodes, which are important agricultural plant pests. 54 isolates from diverse geographical regions and several nematode hosts were used in this study. Genetic variation was examined using enterobacterial repetitive intergenic consensus (ERIC) primed PCR and sequences from the internal transcribed spacer (ITS) rRNA region. ERIC PCR yielded 35 scorable binary characters from all the fungi tested and cluster analysis of the data showed th

Antibiotics LL-Z1272 identified as novel inhibitors discriminating bacterial and mitochondrial quinol oxidases.

To counter antibiotic-resistant bacteria, we screened the Kitasato Institute for Life Sciences Chemical Library with bacterial quinol oxidase, which does not exist in the mitochondrial respiratory chain. We identified five prenylphenols, LL-Z1272beta, gamma, delta, epsilon and zeta, as new inhibitors for the Escherichia coli cytochrome bd. We found that these compounds also inhibited the E. coli bo-type ubiquinol oxidase and trypanosome alternative oxidase, although these three oxidases are structurally unrelated. LL-Z1272beta and epsilon (dechlorinated derivatives) were more active against cy

Suppression of tryptophan synthase activates cotton immunity by triggering cell death via promoting SA synthesis.

Primary metabolism plays an important role in plant growth and development, however the relationship between primary metabolism and the adaptive immune response is largely unknown. Here, we employed RNA interference (RNAi), virus-induced gene silencing (VIGS) technology, phytohormone profiling, genetic studies, and transcriptome and metabolome analysis to investigate the function of the tryptophan synthesis pathway in the resistance of cotton to V. dahliae. We found that knock-down of GbTSA1 (Tryptophan Synthase α) and GbTSB1 (tryptophan synthase β) induced a spontaneous cell death phenotype i

Влияние ПГПР на структуру микробиологической сообщества ризосферы и урожайность солончаковых зерновых культур.

Растворяющиеся в почве бактерии, способствующие росту растений (PGPR), могут защищать растения от почвенных заболеваний и абиотических стрессовых условий. Основная цель данного исследования заключалась в оценке влияния различных PGPR (TF1, TF2, TF3 и TF4) на микробную сообщество ризосферы зерна для корма в солончаково-щелочной поле с использованием высокопроизводительной технологии последовательного секвенирования Illumina MiSeq. Результаты показали, что различные PGPRs значительно увеличили плотность уборки (на 21,31–45,16%), высоту растения (на 9,12–19,98%), диаметр стебля (на 30,07–45,78%)

First Report of Diplodia seriata as Causal Agent of Olive Dieback in Croatia.

In August 2010, a dieback of young olive (Olea europea L.) trees (cvs. Pendolino and Leccino) occurred in two orchards in Istria, Croatia. According to the producers, low temperatures during the winter severely damaged the plants and led to their decline. Distinctive symptoms, assumed fungal infection, were observed in internal tissue of stems and branches. Elongated brown necrosis, sometimes with black streaks, was visible under the bark, therefore Verticillium wilt was suspected. Of 1,086 trees in two orchards (4 ha), 165 (15%) showed symptoms. To isolate the causal agent, surface-sterilized…

Разъяснение роли GRK2: от иммунного регулирования к терапии рака.

G белковые рецепторы (GPCR) представляют собой наиболее заметное семейство мембранных белков. В противоположность этому, G-белковые рецепторы (GRKs) играют ключевую роль в быстрой десенсибилизации ГПКР. GRK2 является особенно важным членом семьи GRK. Недавние исследования показали, что GRK2 в первую очередь регулирует функции иммунных клеток и гомеостаз через десенсибилизацию рецептора. За последнее десятилетие был достигнут существенный прогресс в разъяснении роли GRK2 в различных заболеваниях человека. В частности, GRK2 имеет отношение к целому ряду аутоиммунных расстройств, включая ревматуи
