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...

Top, tree or Egyptian onion, Allium x proliferum (Moench) Schrader, 2n=2x=16, is a minor, vegetatively propagated garden crop in Europe, North America and North East Asia. Several clones of the top onion were found to be locally cultivated in the region of South Croatia under the name “Ljutika-talijanka”. One of these, clone Biorina, was studied by means of both classi­ cal cytogenetic techniqu...

Forty one plants of alien monosomic addition lines of Allium fistulosum L. with extra chromosomes from A. cepa L. Aggregatum group (FF + nA) were produced through the second backcross of amphidiploids between these two species to A. fistulosum. Identification of the extra chromosomes in the 16 plants by elaborate karyotype analyses indicate that a complete series (eight different types) of the ...

Here, we report a comparative study of the phytochemical profile and the biological activity of two onion extracts, namely Allium cepa L. and Allium × cornutum (Clementi ex Visiani 1842), members of the family Amaryllidaceae. The identification of flavonoids and anthocyanins, and their individual quantities, was determined by high-performance liquid chromatography (HPLC). The potency of both ex...

Allium sativum linn (Garlic) belong to family Liliaceae has been widely known since ancient times for medicinal use and for flavouring food. It contains large amount of sulphur containing compounds like Alliin, Allicin, Ajoene, Diallyl sulphide, Diallyl disulphide Diallyl trisulfide, Vinyldithiines which has beneficial activity including Antithrombotic, Anticancer, Antiviral, Antifungal and Ant...

Lachrymatory factor synthase (LFS) catalyzes the formation of lachrymatory factor, one of the most distinctive traits of bulb onion (Allium cepa L.). Therefore, we used LFS as a model for a functional gene in a huge genome, and we examined the chromosomal organization of LFS in A. cepa by multiple approaches. The first-level analysis completed the chromosomal assignment of LFS gene to chromosom...

The genotoxicity of two widely used drinking water disinfectants, sodium hypochlorite (NaClO) and chlorine dioxide (ClO(2)), and a new disinfectant, peracetic acid (PAA, CH(3)-CO-COOH), was evaluated in three short-term plant tests: (1) induction of anaphase chromosome aberrations in the root cells of Allium cepa, (2) micronucleus induction in the root cells of Vicia faba, and (3) micronucleus ...

AIMS The current study was designed to document medicinal plant species that are traditionally used to treat tuberculosis (TB) by Ghanaian communities. METHODS The medicinal plants used against TB or its signs and symptoms were selected using library and online published data searches. A guided questionnaire interview was also conducted with a botanist involved in plant collection at the Cent...

Allium cepa, Guard Cell Protoplasts, Malate, Vicia faba Isolated and purified guard cell protoplasts of starch-containing ( Vicia faba) and starch-lacking (Allium cepa) stomata were used to study the metabolism of malate and Clanions as correlated with the K +-induced swelling of protoplasts. The correlation between swelling and malate synthesis in starch-containing and the inhibition of this c...
