Transient transformation is simpler, more efficient and economical in analyzing protein subcellular localization than stable transformation. Fluorescent fusion proteins were often used in transient transformation to follow the in vivo behavior of proteins. Onion epidermis, which has large, living and transparent cells in a monolayer, is suitable to visualize fluorescent fusion proteins. The oft...

Onion thrips, Thrips tabaci Lindeman, is a worldwide pest of onion whose feeding damage and transmission of Iris yellow spot virus (IYSV) may reduce onion yields. Little is known about the seasonal dynamics of T. tabaci dispersal, the distance of dispersal, or the movement of thrips infected with IYSV during the onion-growing season. To address these questions, T. tabaci adults were collected u...

The main purpose of this study was to reveal if the UV-A, and visible light reflection of leaves of white cabbage varieties is correlated to resistance against onion thrips. The antixenotic resistance (AR) against onion thrips and thrips damage differed between varieties Balashi, Bloktor, Riana - considered resistant - and Green Gem, Hurricane, Quisor - considered susceptible. The solar UV-A (3...

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...

ABSTRACT Xanthomonas leaf blight has become an increasingly important disease of onion, but the diversity among Xanthomonas strains isolated from onion is unknown, as is their relationship to other species and pathovars of Xanthomonas. Forty-nine Xanthomonas strains isolated from onion over 27 years from 10 diverse geographic regions were characterized by pathogenicity to onion and dry bean, fa...

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...

This study investigates onion producers’ technical efficiency level in Kebbi State. Purposive and simple random sampling procedures were adopted selecting 210 producers using structured questionnaire from seven local government areas the state. Descriptive statistics, gross margin stochastic frontier production models employed describing analyzing data. The results showed that generated an aver...

Allium vegetables have been employed for a long time in traditional medical practice to treat a variety of diseases. Onion (Allium cepa L.), one of the representative Allium vegetables, has been used for centuries for its pungency, flavoring value, and medicinal properties. The bulb of onion is used medicinally and has been consumed as seasoning food for many centuries (Sengupta et al., 2004). ...
