Antifungal activity of recombinant rice LTP2 on some phytopathogenic fungi
Plant lipid transfer proteins (LTPs) are members of the pathogenesis-related proteins (PR-14) and some of them exhibit activity against phytopathogenic fungi. To investigate whether rice LTP2 plays a role in antifungal activity, the coding region of an Iranian rice Ltp2 gene was cloned into expression vector pET24-d(+) and then expressed in Escherichia coli Rosetta strain (DE3). The potential a...
متن کاملDiversity of toxic and phytopathogenic Fusarium species occurring on cereals grown in Karnataka state, India
A total of 198 cereal samples (53 maize, 54 sorghum, 37 paddy and 54 wheat) were collected from 11 districts of Karnataka to understand the percent infection (PI), relative density (RD) and their frequency (Fr) caused by Fusarium spp. All samples were screened by agar plating method using MGA 2.5 agar media and incubated at 25 ± 2 °C for 3-5 days. The study revealed the association of 10 differ...
متن کاملSome ice nucleation characteristics of Asian and Saharan desert dust
The large (7 m×4 m cylinder, 84 m3) AIDA (Aerosol Interactions and Dynamics in the Atmosphere) cloud chamber facility at Forschungszentrum, Karlsruhe, Germany was used to test the ice nucleating ability of two desert dust samples from the Sahara and Asia. Aerosol samples were lognormally distributed with a mode diameter of 0.4(±0.1)μm and geometric standard deviation of ∼1.7(±0.2). At temperatu...
متن کاملIce nucleation activity in the widespread soil fungus Mortierella alpina
Biological residues in soil dust are a potentially strong source of atmospheric ice nuclei (IN). So far, however, the abundance, diversity, sources, seasonality, and role of biological – in particular, fungal – IN in soil dust have not been characterized. By analysis of the culturable fungi in topsoils, from a range of different land use and ecosystem types in southeast Wyoming, we found ice-nu...
متن کاملEffect of Plant Species and Environmental Conditions on Ice Nucleation Activity of Pseudomonas syringae on Leaves.
Selected plant species and environmental conditions were investigated for their influences on expression of ice nucleation activity by 15 Pseudomonas syringae strains grown on plants in constant-temperature growth chamber studies. Ice nucleation frequencies (INFs), the fraction of cells that expressed ice nucleation at -5 or -9 degrees C, of individual strains varied greatly, both on plants and...
