A leaf blight of carrot (Daucus carota) caused by Alternaria dauci was found in Alentejo (Ourique, Portugal). Morphological characteristics of the fungus are described.

Heritability of resistance to gummy stem blight (Didymella bryoniae (Auersw.) Rehm.) was measured in two diverse cucumber (Cucumis sativus L.) populations [North Carolina elite slicer 1 (NCES1) and North Carolina wide base pickle (NCWBP)]. Heritability was estimated using parent–offspring regression and half-sib family analysis in North Carolina field tests during 1991 and 1992. NCES1 is a slic...

Some of the proteins and enzymes that allow bacteria to enter living fungal cells and cause rice seedling blight have been identified.

Fusarium head blight is one of the most important and most common diseases of winter wheat. In order to better understanding this disease and to assess the correlations between different factors, 30 cultivars of this cereal were evaluated in a two-year period. Fusarium head blight resistance was evaluated and the concentration of trichothecene mycotoxins was analysed. Grain samples originated f...

Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...

Blast, Magnaporthe oryzae B. Couch, and sheath blight, Rhizoctonia solani Kühn, are major fungal diseases of cultivated rice (Oryza sativa L.) in theUSA. Resistance toU.S.M. oryzae races was observed in 91 newly introduced rice accessions, suggesting these accessions are possible sources of novel blast resistance genes (Pi-genes) that could be incorporated into U.S. rice cultivars. The genes Pi...

in the current study, molecular typing of 50 erwinia amylovora strains related to different regions in iran was evaluated using multi-locus sequence analysis and variable number of tandem repeats. in the first assay, phylogenetic tree based on partial sequences of recombinase a, sigma factor s and a heat shock protein groel showed significant identity in studied gene sequences. a single nucleot...

Ascochyta blight of lentil is a prevalent disease in many lentil producing regions and can cause major yield and grain quality losses. The most environmentally acceptable and economically profitable method of control is to develop varieties with high levels of durable resistance. Genetic studies to date suggest that ascochyta blight resistance genes (R-gene) in lentil lines CDC Robin, ILL 7537,...

Glutaredoxins (GRXs) belong to the antioxidants involved in the cellular stress responses. In spite of the identification 48 GRX genes in rice genomes, the biological functions of most of them remain unknown. Especially, the biological roles of members of GRX family in disease resistance are still lacking. Our proteomic analysis found that OsGRX20 increased by 2.7-fold after infection by bacter...

X-ray irradiation with convergent chemicals such as nano-silver particles or sodium dichloroisocyanurate (NaDCC) has been used to control leaf blight on cut lilies. The oriental hybrid lily cultivars Siberia, Le Reve, and Sorbonne were irradiated five times by 200 Gy of X-rays in 2014. In 2015, Siberia and Sorbonne were irradiated three times by 150 Gy of X-rays. After artificial infection with...
