A so-called R-gene renders the yellow-striped flea beetle Phyllotreta nemorum L. (Coleoptera: Chrysomelidae: Alticinae) resistant to the defenses of the yellow rocket Barbarea vulgaris R.Br. (Brassicacea) and enables it to use it as a host plant in Denmark. In this study, genetic markers for an autosomal R-gene, inherited as a single, dominant locus in flea beetles from the Danish locality "Kva...
Plant species are living things and are generally categorized in terms of Domain, Kingdom, Phylum, Class, Order, Family, Genus and name of Species in a hierarchical fashion. This paper formulates the taxonomic leaf categorization problem as the hierarchical classification task and provides a suitable solution using a supervised learning technique namely support vector machine. Features are extr...
Typical postharvest storage of broccoli (Brassica oleracea var. italica) causes degreening of this common vegetable with visible loss of chlorophyll (Chl). As shown here, colorless Chl-catabolites are generated. In fresh extracts of degreening florets of broccoli, three colorless tetrapyrrolic Chl-catabolites accumulated and were detected by high performance liquid chromatography (HPLC): two "n...
Purified isothiocyanates from cruciferous plants (Brassicacea, Syn. Cruciferae) plants were evaluated against 15 isolates of methicillin-resistant S. aureus isolated from diabetic foot-ulcer patients aiming the study of the potential usage of allyl-isothiocyanate, benzyl-isothiocyanate and 2-phenylethyl-isothiocyanate against this important bacteria. Disc diffusion and minimum inhibitory concen...
General transcription factor IIB (TFIIB) and TFIIB-related factor (BRF), are conserved RNA polymerase II/III (RNAPII/III) selectivity factors that are involved in polymerase recruitment and transcription initiation in eukaryotes. Recent findings have shown that plants have evolved a third type of B-factor, plant-specific TFIIB-related protein 1 (pBRP1), which seems to be involved in RNAPI trans...
We compared the sequence of a 101-kb-long bacterial artificial chromosome (BAC) clone (B21H13) from Brassica oleracea with its homologous region in Arabidopsis thaliana. This clone contains a gene family involved in the synthesis of aliphatic glucosinolates. The A. thaliana homologs for this gene family are located on chromosome IV and correspond to three 2-oxoglutarate-dependent dioxygenase (A...
Bakteriler antibiyotiklere ve türevlerine karşı günden güne direnç kazanmaktadır bu küresel bir sorun haline gelmektedir. Bitkilerde bulunan sekonder metabolitlerin (fenolik bileşikler, flavonoidler, alkoloidler gibi) antioksidan antimikrobiyal gibi çeşitli aktiviteleri sebebiyle sorunun önüne geçilebileceği düşünülmektedir. Bu kapsamda çalışmalar yapılmış halen de yapılmaktadır. Bitkisel kayna...
The role of many genes and interactions among genes involved in flowering time have been studied extensively in Arabidopsis, and the purpose of this study was to investigate how effectively results obtained with the model species Arabidopsis can be applied to the Brassicacea with often larger and more complex genomes. Brassica rapa represents a very close relative, with its triplicated genome, ...
