Trichovariability in rhizosphere soil samples and their biocontrol potential against downy mildew pathogen in pearl millet.

The present work is aimed to examine the genetic variability and the distribution pattern of beneficial Trichoderma spp. isolated from rhizosphere samples and their mode of action in improving the plant health. A total of 131 suspected fungi were isolated from the rhizospheric soil and 91 isolates were confirmed as Trichoderma spp.

Total crude protein extract of Trichoderma spp. induces systemic resistance in pearl millet against the downy mildew pathogen.

Several proteins and peptides of microbial origin are reported for their elicitor properties, which play a vital role in the development of local and systemic resistances in plants. In this study, the efficacy of total crude proteins (TCP) extracted from six different Trichoderma spp. (T.

Trichogenic-selenium nanoparticles enhance disease suppressive ability of Trichoderma against downy mildew disease caused by Sclerospora graminicola in pearl millet.

Trichoderma spp. are well known biocontrol agents used against phytopathogens. In the present work Trichoderma-mediated Selenium nanoparticles (SeNPs) were synthesized and extent of downy mildew (DM) disease control in pearl millet (PM) was studied.

Genetic diversity and antimicrobial activity of endophytic Myrothecium spp. isolated from Calophyllum apetalum and Garcinia morella.

Calophyllum apetalum and Garcinia morella, medicinal plants are endemic to Western Ghats, Karnataka, India. Sixteen Myrothecium isolates were obtained from the tissues of bark and twigs of these plants. The purpose of this study was to explore the antimicrobial activity and genetic variability of the endophytic Myrothecium isolates.

Bioactive potential of endophytic Myrothecium sp. isolate M1-CA-102, associated with Calophyllum apetalum.

Context: Endophytes colonizing medicinal plants are diverse, constituting a rich bioresource for novel natural products.

Objective: Myrothecium sp. isolate M1-CA-102 was the most promising among the 16 Myrothecium isolates screened.

Inhibition of TMV multiplication by siRNA constructs against TOM1 and TOM3 genes of Capsicum annuum.

The host proteins TOM1 and TOM3 associated with tonoplast membrane are shown to be required for efficient multiplication of Tobamoviruses. In this study, homologous of TOM1 and TOM3 genes were identified in pepper (Capsicum annuum) using specific primers. Their gene sequences have similarity to Nicotiana tabacum NtTOM1 and NtTOM3.

Transcriptome changes in foxtail millet genotypes at high salinity: identification and characterization of a PHGPX gene specifically upregulated by NaCl in a salt-tolerant line.

Using a macro array filter with 711 cDNA inserts representing 620 unigenes selected from a barley EST collection, we identified transcripts differentially expressed in salt (NaCl)-treated tolerant (cv. Prasad) and sensitive (cv. Lepakshi) seedlings of foxtail millet (Setaria italica L.
