The intergenic spacer (IGS) region of rDNA in Daucus carota contains at least eight kinds of repeated sequence. One sequence may act as a genuine initiation site for a stable transcript and another may act as a spacer promoter that may be an entry site for proteins required for transcription.

The effect of surfactants on the bioreduction of acetophenones mediated by carrot (Daucus carota) root was investigated. Among the tested surfactants, Tween® 20 slightly improved the conversion. The amount of surfactant was optimised, and the presented methodology was applied to other substituted acetophenones, which led to the preparation of their respective optically enriched 1-phenylethanols...

Two new guaiane-type sesquiterpene glycosides, 11-O-acetyl-torilolone 8-O-beta-D-glucopyranoside (1) and 1beta-hydroxytorilolone 11-O-beta-D-glucopyranoside (2), were isolated from the fruits of Daucus carota L. Their chemical structures were elucidated on the basis of MS, NMR spectroscopic analyses coupled with chemical degradation.

We studied the phylogeny of 22 accessions of Daucus and seven accessions in related genera, with DNA sequences from eight nuclear orthologs and one plastid (psbA/trnH) region. Maximum parsimony and maximum likelihood analyses of the concatenated data matrix of 7,212 aligned nucleotides provided excellent bootstrap support for many clades. Concordant with prior molecular results Pseudorlaya pumi...

In biotransformations carried out under similar conditions enzymatic systems from carrot (Daucus carota L.), celeriac (Apium graveolens L. var. rapaceum) and horse-radish (Armoracia lapathifolia Gilib.) hydrolyzed the ester bonds of acetates of phenols or alicyclic alcohols. Nevertheless, methyl esters of aromatic acids did not undergo hydrolysis. Alcohols were oxidized to ketones in a reversib...

background & aims of the study: vegetables and cereals are considered vital for properly-balanced diet given that they deliver vitamins, minerals, nutritional fiber, and phytochemicals. this study aimed to assess the concentration of as, cu, cd, pb, cr and hg in common vegetables and cereals in urban open markets in varanasi district, india materials & methods: total 260 edible portions of vege...

We isolated the cDNA clone coding for a major root specific protein (CR16) of carrots. The CR16 protein (154a.a.) has a high homology to intracellular pathogenesis-related (PR) proteins, stress-induced proteins and also the major allergen protein of celery (Api g1). The CR16 protein gene formed a super gene family and transcripts of this CR16 protein gene are predominant in root tissue, not in ...

The reproductive factor (R = final egg density at 55 days / 5,000, initial egg density) of Meloidogyne chitwoodi race 2 (alfalfa race) on 46 crop cultivars ranged from 0 to 130. The reproductive efficiency of M. chitwoodi race 1 (non-alfalfa race) and M. chitwoodi race 2 was compared on selected crop cultivars. The basic difference between the two races lay in their differential reproduction on...
