457 Onion (Allium cepa L.) is an important export oriented vegetable among the cultivated allium in India. It is also known as “queen of kitchen”. Productivity of onion is affected by many biotic and abiotic stresses. For commercial cultivation of onion, both thrips and foliar diseases play the key role in reducing the bulb yield and quality of produce. Among the various foliar diseases affecti...

Leaf blotch of wheat caused by Bipolaris sorokiniana is a major constraint to wheat production, causing significant yield reduction resulting in severe economic impact. The present study characterizes to determine and compare pathogenic variability exist/not based on components of leaf blotch disease development and level of aggressiveness due to agroclimatic condition of B. sorokiniana in whea...

septoria tritici blotch is an important wheat disease in many areas of the world including iran's warm, humidregions. in this study, crosses were made between resistant breeding line bobwhite#1/fengkang andcommercial cultivars moghan3, koohdasht, tajan and morvarid, and derived f1, f2, bc1 and bc2 generations were used to determine the genetic control of necrosis, pycnidia traits and the area u...

Helically chiral N,N,O,O-boron chelated dipyrromethenes showed solution-phase circularly polarized luminescence (CPL) in the red region of the visible spectrum (λem (max) from 621 to 663 nm). The parent dipyrromethene is desymmetrised through O chelation of boron by the 3,5-ortho-phenolic substituents, inducing a helical chirality in the fluorophore. The combination of high luminescence dissymm...

The Mycosphaerella complex is both poly- and paraphyletic, containing several different families and genera. The genus Mycosphaerella is restricted to species with Ramularia anamorphs, while Septoria is restricted to taxa that cluster with the type species of Septoria, S. cytisi, being closely related to Cercospora in the Mycosphaerellaceae. Species that occur on graminicolous hosts represent a...

A new labrid fish Terelabrus dewapyle sp. nov. is described as the second species of the genus, on the basis of five specimens collected from southern Japan, Papua New Guinea, and Fiji in depths of 72-92 m. The sole paratype of T. rubrovittatus Randall & Fourmanoir 1998 is herein identified as T. dewapyle and designated as a paratype of the latter. The new species can be distinguished from T. r...

Blotches are common artifacts in old film sequences that manifest themselves as disturbing bright or dark spots. Existing methods for detecting blotches can achieve high detection rates. High detection rates are only useful if the corresponding number of false alarms is not too high, visible artifacts in the corrected sequence result otherwise. We show that the performance of blotch detectors c...

The draft genome sequence of Pseudomonas gingeri LMG 5327 (NCPPB 3146), the causative agent of ginger blotch in Agaricus bisporus, is reported. Together with another mushroom pathogen, Pseudomonas agarici, it belongs to a distinct phylogenomic group.

Grapevine red blotch-associated virus (GRBaV) was isolated from table and wine grapes, as well as rootstocks, affected by red blotch, a recently recognized viral disease. Phylogenetic analyses revealed the clustering of GRBaV isolates two groups (clades) of genetic variants (Krenz et al., 2014, Al Rwahnih et al., 2015). Producing and using a full-length infectious clone of a representative isol...

-Twenty four isolates of peanut stripe virus from 8 d1fferent countnes were compared under controlled cond1tions at the Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD). Montpelher, France. The isolates had thetr origins from Burma, lndia, Jndones1a, Phîhppincs, China. Tha1\and and USA. Four of the isolates were collected from Thaîland in 1972 but mamt...
