: a new species from vineyard ecosystem with biocontrol abilities against grapevine trunk disease pathogens and ecological adaptation.

strains used in vineyards for the control of grapevine trunk diseases (GTDs) present a promising alternative to chemical products. Therefore, the isolation and characterization of new indigenous strains for these purposes is a valuable strategy to favor the adaptation of these strains to the environment, thus improving their efficacy in the field. In this research, a new species, , isolated from vineyards in Ribera de Duero (Spain) area, has been identified and phylogenetically analyzed using 20 housekeeping genes isolated from the genome of 24 species.

Vineyard Management and Physicochemical Parameters of Soil Affect Native Populations, Sources of Biocontrol Agents against .

Native strains of in vineyard soil represent an opportunity for reducing the incidence of grapevine trunk diseases (GTDs) in vineyards. Moreover, its relationship with the environment (physicochemical soil characteristics and farming management practices) remains unclear. In the current study, a survey was carried out on farming management used by viticulturists, and soil samples were studied to analyze their physicochemical properties and to isolate strains.

Spores of Strains over Beans: Direct Effect on Insect Attacks and Indirect Effect on Agronomic Parameters.

is an insect pest that attacks wild and cultivated common beans ( L). Four strains, the IBT 40837 wild-type strain (=Ta37), a producer of trichothecene harzianum A (HA), two transformants of strain, Ta37-17.139 (=Δ17) and Ta37-23.

Effect of Farnesol in Physiology and in Fungal-Plant Interaction.

Farnesol is an isoprenoid intermediate in the mevalonate (MVA) pathway and is produced by the dephosphorylation of farnesyl diphosphate. Farnesol plays a central role in cell growth and differentiation, controls production of ubiquinone and ergosterol, and participates in the regulation of filamentation and biofilm formation. Despite these important functions, studies of farnesol in filamentous fungi are limited, and information on its effects on antifungal and/or biocontrol activity is scarce.

Effects of trichothecene production by isolates from bean-field soils on the defense response, growth and development of bean plants ().

The trichothecene toxin-producing fungus has potential as a biological control agent. However, most biocontrol studies have focused only on one strain, IBT 40837. In the current study, three isolates recovered from bean-field soils produced the trichothecene harzianum A (HA) and trichodermol, the latter being an intermediate in the HA biosynthesis.

Organic and Conventional Bean Pesticides in Development of Autochthonous Strains.

Pesticides of chemical synthesis have mainly been used to control pests, diseases and adventitious plants up until now. However, it has been shown that some pesticides can remain in the soil for long periods of time, thus affecting the development of organisms in the rhizosphere as well as human health, which are two of the most noteworthy side effects. The aim of this research was to analyze the compatibility of autochthonous strains with different synthetic fungicides, acaricides, insecticides (including an entomopathogenic fungus) and herbicides.

Xylotrechus arvicola (Coleoptera: Cerambycidae) capture in vineyards in relation to climatic factors.

Background: Captures and seasonal abundance of Xylotrechus arvicola (Coleoptera: Cerambycidae) in relation to climatic factors were studied in vineyards between the years 2013 and 2020. Insects captures from vine wood in two Vitis vinifera varieties were evaluated every year by counting the number of insects captured with CROSSTRAP®. The captured insects were grouped (by sex and total) into ranges of 10 days and compared to climatic data (daily average, temperature and rainfall) for each cultivar and year.

Distribution, Function, and Evolution of a Gene Essential for Trichothecene Toxin Biosynthesis in .

Trichothecenes are terpenoid toxins produced by species in 10 fungal genera, including species of . The trichothecene biosynthetic gene () cluster typically includes the gene, which encodes a terpene synthase that catalyzes formation of trichodiene, the parent compound of all trichothecenes. The two species, and , that have been examined are unique in that is located outside the cluster in a genomic region that does not include other known genes.

Volatile Organic Compound Chamber: A Novel Technology for Microbiological Volatile Interaction Assays.

The interest in the study of microbiological interactions mediated by volatile organic compounds (VOCs) has steadily increased in the last few years. Nevertheless, most assays still rely on the use of non-specific materials. We present a new tool, the volatile organic compound chamber (VOC chamber), specifically designed to perform these experiments.

Colonization of L. by the Endophyte sp. Strain T154: Biocontrol Activity Against .

strains used in biological control products usually exhibit high efficiency in the control of plant diseases. However, their behavior under field conditions is difficult to predict. In addition, the potential of indigenous strains has been poorly assayed as well as their possible behavior as endophytes.

Investigations of Trichoderma spp. and Beauveria bassiana as biological control agent for Xylotrechus arvicola, a major insect pest in Spanish vineyards.

Xylotrechus arvicola (Olivier) (Coleoptera: Cerambycidae) is an important pest in vineyards (Vitis vinifera) in the main wine-producing regions of Spain. Effective control of this pest is difficult due to the biology of this pest. Biological control agents (BCAs) have proven to be an effective tool in controlling and preventing the spread of a variety of plant pests and diseases.
