Although allelic diversity of genes has been reported to play important roles in different physiological processes, information on allelic diversity of defense-responsive genes in host-pathogen interactions is limited. Here, we report that a pair of allelic genes, OsWRKY45-1 and OsWRKY45-2, which encode proteins with a 10-amino acid difference, play opposite roles in rice (Oryza sativa) resista...

An analysis of siderophores produced by Magnaporthe grisea revealed the presence of one intracellular storage siderophore, ferricrocin, and four coprogen derivatives secreted into the medium under iron depletion. Structural analysis showed that the compounds are coprogen, coprogen B, 2-N-methylcoprogen and 2-N-methylcoprogen B. Siderophore production under low and high iron conditions was quant...

Verdamicin is a new aminoglycoside antibiotic isolated from fermentation broths of a species of the genus Micromonospora, M. grisea. It has been differentiated from other known related antibiotics by a variety of chemical and biological methods. Its in vitro and in vivo spectrum of activity appears to be similar to those of gentamicin and sisomicin.

A recent survey of the entomofauna Davis Mountains in state Texas has revealed four new species genus Phytocoris Fallén (Miridae, Mirinae, Mirini): mcivor sp. nov. and schmitzi found on Quercus grisea Liebmann, marqua rileyi attracted to lights. Descriptions, habitus, genitalic images for are included herein. Further, habitus photographs known from county aid identification.

The article presents new floristic novelties of Veronica L. subgenus Pseudolysimachium (Plantaginaceae) the Altai Mountain Country and adjacent areas. For first time, × grisea Kosachev et A. Ebel was collected in Republic Altai, V. pinnata is indicated for Novosibirsk Region. In addition, locations 7 rare endemic species are given. Point distribution maps given most species.

Rice (Oryza sativa L.) is a major staple food crop for half of the world’s population. The International Rice Research Institute, Philippines, estimates that in order to feed the growing global population, rice production must increase by another one-third by the year 2020. Magnaporthe grisea (anamorph, Pyricularia oryzae) causes rice blast disease (Figure 1) and is the most destructive pathoge...
