Drought-induced tree mortality has been observed worldwide. Nevertheless, the physiological mechanisms underlying this phenomenon are still being debated. Potted Robinia pseudoacacia and Platycladus orientalis saplings were subjected to drought and their hydraulic failure and carbon starvation responses were studied. They underwent simulated fast drought (FD) and slow drought (SD) until death. ...

The common soil fungus Trichoderma (teleomorph Hypocrea, Ascomycota) shows increasing medical importance as an opportunistic human pathogen, particularly in immunocompromised and immunosuppressed patients. Regardless of the disease type and the therapy used, the prognosis for Trichoderma infection is usually poor. Trichoderma longibrachiatum has been identified as the causal agent in the majori...

AFLP was used to analyze the genetic diversity among Ochrobactrum strains. AFLP patterns showed a great genomic variability that separated the samples into three distinct clusters. Ochrobactrum intermedium was found to be closely related to Brucella abortus S99.

Speciation and allopolyploidization in cereals may be accompanied by dramatic changes in abundance of centromeric repeated transposable elements. Here we demonstrate that the reverse transcriptase part of Ty3/gypsy centromeric retrotransposon (RT-CR) is highly conservative in the segmental hexaploid Thinopyrum intermedium (JrJvsSt) and its possible diploid progenitors Th. bessarabicum (Jb), Pse...

Thinopyrum intermedium is resistant to many different pathogens. To understand the roles of ethylene response factors (ERFs) in defence responses, the first member of the ERF family in T. intermedium, TiERF1, was characterized and functionally analysed in this study. The TiERF1 gene encodes a putative protein of 292 amino acids, belonging to the B3 subgroup of the ERF transcription factor famil...

Amycolatopsis orientalis CPCC200066 is an actinomycete that can produce the glycopeptide antibiotic norvancomycin, which has significant inhibitory activity against Gram-positive cocci and bacilli. Here, we report the draft genome sequence of A. orientalis CPCC200066 and identified the genes involved in norvancomycin biosynthesis.

This paper explores the relationship between the genetic diversity of rhizobia and the morphological diversity of their plant hosts. Rhizobium galegae strains were isolated from nodules of wild Galega orientalis and Galega officinalis in the Caucasus, the center of origin for G. orientalis. All 101 isolates were characterized by genomic amplified fragment length polymorphism fingerprinting and ...

Amblyseius swirskii, native to the east and southeast Mediterranean region, is a successful biological control agent of whiteflies. In this study, we investigated intraguild predations (IGP) between each stage of A. swirskii and each stage of two Phytoseiid species that occur in China, Amblyseius orientalis and Neoseiulus californicus. When there was no whitefly egg provided as the extraguild p...

Goal. To select the best perennial grasses for lucerne-cereal mixtures on different agricultural backgrounds to increase their productive longevity produce high-quality grass fodder. Methods. Field, laboratory, mathematical and statistical, computational comparative. Results. The results are given of research (2019–2021) in formation forage productivity lucerne, with various cereal components a...

During the present study Diplocystis kasmirensis n. sp. (Sporozoa: Eugregarinida) were collected from Haemocoel including gut surface of Blatta orientalis Linnaeus (Dictyoptera; Blattidae) with description to their morphology, life cycle stages and taxonomy. Gregarine Parasite Belonging to the Family Diplocystidae Bhatia, 1938 Reported from the Cockroaches Blatta orientalis (Dictyopetra: Blatti...
