Isoforms of onion bulb GSTs (designated as GSTa, GSTb, as minor, and GSTc, GSTd and GSTe as dominant GSTs) were separated by DEAE-cellulose chromatography, and variation in the activity of dominant GSTs was studied in winter and spring. Among the dominant GSTs, GSTc and GSTd were found to have similar activity levels in both seasons. In case of GSTe, distinct activity levels were observed in wi...

Nutritional constraints often restrict yields of crops in farmers’ fields. Plant nutrient status is currently diagnosed using empirically derived nutrient norms from arbitrarily defined high and low yielding subpopulations above a quantitative yield target. Generic models can assist Compositional Nutrient Diagnosis (CND) in providing a yield cutoff value between high-and lowyielding subpopulati...

Onion (Allium cepa) bulb from Liliaceae has antioxidant, spasmolytic and antihypertensive activities. The aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. Onion peel powder was extracted by maceration in 70% alcohol for 72 h. A terminal portion of ileum from male Wistar rat was dissected and its contractions were recorded isotonically in...

pantoea ananatis is an important pathogen causing bacterial center rot in onion. isolated strains from onion soft rot bulbs based on morphological characteristics were tested for hypersensitivity reaction on tobacco. pathogenic strains underwent some biochemical tests which detected the presence of p. ananatis, based on rna16s sequencing, this result was confirmed. symptoms were reproduced by i...

Every day, half a million people use the onion-routing network Tor [Dingledine et al. 2004] to anonymize their Internet communication. However, the effectiveness of this service, and of onion routing in general, is not well understood. The approach we take to this problem is to model onion routing formally all the way from the protocol details to the behavior of the users. We then analyze the r...

BACKGROUND AND AIMS Exogenous ethylene has recently gained commercial interest as a sprouting inhibitor of onion bulbs. The role of ethylene in dormancy and sprouting of onions, however, is not known. METHODS A cultivar (Allium cepa 'Copra') with a true period of dormancy was used. Dormant and sprouting states of onion bulbs were treated with supposedly saturating doses of ethylene or with th...

The decision modeling process requires much time and effort, and the resulting model, such as an influence diagram is applicable to only one specific problem. Existing studies reusing prior knowledge have some drawbacks, such as knowledge representation or lack of case problems. The basic idea of case-based reasoning is that humans reuse the problem solving experience to solve current problems....

abstract in order to detect onion yellow dwarf virus in khorasan province in iran, onion samples from major onion growing regions where collected in spring and summer 2010. to determine the distribution of the virus, samples were randomly taken from onion fields in vicinity of mashhad, chenaran, quchan, torbate heydarye, neyshabur, bardaskan, gonabad, fariman, faruj, shirvan, bojnourd and ash k...
