study of some growth promotion properties of bacterial isolates from animal manures and identification of selected isolatesabstractbackground and objectives: plants growth in agricultural soils are affected by several biological factors. plant growth promoting bacteria can improve growth and yield of agronomic plants through direct and indirect mechanisms. minimizing consequences of using high ...

Piriformospora indica, a member of basidiomycota is an axenically cultivable endophytic fungus which exerts plant growth promoting effects on its host plant. P. indica is known to produce α-amylase and protease. Since the organism exhibits beneficial role in plant growth promotion, achieving high biomass is immensely essential. Hence to enable the commercial production, screening of medium comp...

Human immunodeficiency virus type 1 protease (HIV-1 PR) is an essential enzyme for the replication cycle of HIV. HIV-1 PR inhibitors have been extensively investigated as anti-AIDS drugs. In the presence of HIV-1 protease inhibitors, the virion is unable to mature. Natural compounds are important sources of drugs. The present investigation concentrates on discovering anti-HIV compounds that are...

The basidiomycete Ustilago maydis causes smut disease in maize, with large plant tumors being formed as the most prominent disease symptoms. During all steps of infection, U. maydis depends on a biotrophic interaction, which requires an efficient suppression of plant immunity. In a previous study, we identified the secreted effector protein Pit2, which is essential for maintenance of biotrophy ...

We have isolated and sequenced a 1400-base-pair cDNA derived from gibberellic acid-treated aleurone cell mRNA. This sequence contains an open reading frame that would code for a protein of 361 amino acids. The carboxyl-terminal two-thirds of the predicted amino acid sequence is closely related to that of the rat lysosomal thiol protease cathepsin H; the initial 143 amino acids may code for a se...

The Arabidopsis thaliana genome has over 550 protease sequences representing all five catalytic types: serine, cysteine, aspartic acid, metallo and threonine (MEROPS peptidase database, http://merops.sanger.ac.uk/), which probably reflect a wide variety of as yet unidentified functions performed by plant proteases. Recent indications that the 26S proteasome, a T1 family-threonine protease, is a...
