Antagonistic actinomycetes from Moroccan soil to control the grapevine gray mold
TLDR
It is demonstrated here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea, indicating the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytic mold.Abstract:
One hundred and forty-two different actinomycete strains were isolated from rhizosphere soil of Vitis vinifera L. sampled from four Moroccan areas. To evaluate the antifungal effect of the different collected actinomycete isolates, five fungi known to be phytopathogens (Pythium ultimum, Fusarium oxyysporum f. sp. albedinis, Sclerotium rolfsii,Verticillium dahliae and Botrytis cinerea) were used. Results showed that 24 isolates had an in vitro inhibitory effect toward at least 4 of the indicator fungi, but only 9 inhibited all these phytopathogens. These nine isolates were subsequently evaluated individually using in vitro grapevine plantlets for their ability to protect against plant gray mold. We demonstrate here that pre-inoculation of plantlets with these isolates allow them to withstand Botrytis cinerea. Six of these strains were shown to belong to the genus Streptomyces and three to the genus Micromonospora. These findings indicate the potential of developing effective actinomycetes from Moroccan habitats for the biological control of Botrytis cinerea.read more

TL;DR: Two novel actinobacteria, designated strains NEAU-QS7T andNEAU-ML10T, were isolated from a root of Sonchus oleraceus L. and a Kronopolites svenhedind Verhoeff specimen, respectively, collected from Wuchang, Heilongjiang Province, China, and showed to form abundant aerial hyphae that differentiated into spherical spore vesicles.

Diversity and Biotechnological Potential of Culturable Rhizospheric Actinomicrobiota
TL;DR: The interface of plant root and soil is the most active region where major parts of maximum number of cycles occur that leads to the accumulation of diverse chemicals of microbial origin and rhizosphere becomes the important hotspot of biotechnological interest.

TL;DR: This review will provide a spotlight on critical issues of the anthropocentric point of view that, until now, has characterized the selection of elite plant genotypes and its effects on the plant-microbiome interactions, and the possibility to develop novel strategies mediated by the exploitation of beneficial root-microbe interactions, will be discussed.

TL;DR: In this article, three strains of actinobacteria belonging to the genus streptomyces and called Strobacterium sp.vv/r1, Strobias sp.v/r4, and Strobia sp. Vv/e1 were selected on the basis of their ability to effectively inhibit the growth of the phytopathogenic fungi llyonectria sp.
