Rice false smut, a fungal disease caused by Ustilaginoidea virens is becoming a severe detriment to rice production worldwide. However, little is known about the molecular response of rice to attacks by the smut pathogen. In this article, we define the initial infection process as having three stages: initial colonization on the pistil (stage 1, S1), amplification on the anther (stage 2, S2) an...

We have isolated major histocompatibility complex (MHC) class II beta loci from the little greenbul (Andropadus virens), an African songbird. We utilized preexisting information about conserved regions of the avian MHC to design primers to amplify a pool of sequences representing multiple loci. From this pool, a unique locus spanning 1109 bp that we designate as Anvi-DAB1 was cloned and sequenc...

six strain of trichoderma (t. viride, t. harzianum, t. reesei, t. longibrachiatum, t. koningii, t. virens) were isolated and used for extracellular enzyme production. species of trichoderma are collected from the surrounding soil of suger beet root fields in east iran, and held in vitro cultured pda. tcm and tfm are used for the growth of spores and induceing the production of cellulase. finall...

1. Two high molecular invertebrate hemoglobins (the erythrocruorins of Lumbricus terrestris and of Nereis virens) as well as the low molecular erythrocruorin of Glycera dibranchiata Ehlers were studied. Their physical chemical properties were compared with those of vertebrate hemoglobin. 2. The hemin of the blood pigment of Glycera dibranchiata Ehlers was shown to be identical with that of vert...

Bu çalışmada, nane yetiştiriciliğinde önemli hastalıklara sebep olan fungal patojenlerden Fusarium oxysporum ve Rhizoctonia solani' ye karşı Trichoderma harzianum virens biyolojik kontrol etmenlerinin etkisi araştırılmıştır. aşamada solgunluk belirtisi gösteren bitkilerinin köklerinden yapılan izolasyonlar sonucunda F. R. solani izolatları elde edilmiş tanıları yapılmıştır. In vivo’da T. biyoet...
