The Arabidopsis Information Resource (TAIR, http://arabidopsis.org) is a genome database for Arabidopsis thaliana, an important reference organism for many fundamental aspects of biology as well as basic and applied plant biology research. TAIR serves as a central access point for Arabidopsis data, annotates gene function and expression patterns using controlled vocabulary terms, and maintains ...

Hairy root culture (HRC) represent a valuable biotechnological tool for the production of plant secondary metabolites. Secondary metabolome study Arabidopsis thaliana may help to understand biological roles various metabolites present in it. The work deals with establishment Agrobacterium rhizogenes strains transformed HRC A. very high transformation frequency resulting long term hairy cultures...

Arabidopsis thaliana has grown from a lowly weed into a model organism of lofty stature and spawned a rapidly growing field of research. A wealth of on-line resources has arisen to coordinate the multicenter Arabidopsis sequencing project. The Arabidopsis Genome Initiative (AGI) provides up-to-date information about ongoing efforts to sequence the five chromosomes of A. thaliana. As of March 20...

BACKGROUND Combining herbicides into a mixture is common approach used to overcome the potential for herbicide resistance in weeds. Many mixtures can be antagonistic and they are rarely synergistic. Here, 24 commercial herbicides, each representing different mode of action were create matrix all 276 unique combinations search new synergies agar using Arabidopsis thaliana. RESULTS Herbicides at ...

Brown alga Ectocarpus sp. belongs to Phaeophyceae, a class of macroalgae that evolved complex multicellularity. is dominant seaweed in temperate regions, abundant mostly the intertidal zones, an environment with high levels abiotic stresses. Previous transcriptomic analysis revealed several genes consistently induced by various stresses; one these Esi0017_0056, which encodes protein unknown fun...

The root system of the plant is essential for taking up water and nutrients, serves as an anchor organ where plant-microorganism interaction takes place. When Plant Growth Promoting Rhizobacteria (PGPR) Azospirillum brasilense Sp245 colonizes plants, it halts growth primary stimulates development lateral roots hairs which support vegetative, green biomass. Target Rapamycin (TOR) a highly conser...

We report that fluorescently tagged arabinogalactan glycosyltransferases target not only the Golgi apparatus but also uncharacterized smaller compartments when transiently expressed in Nicotiana benthamiana. Approximately 80% of AtGALT31A [Arabidopsis thaliana galactosyltransferase from family 31 (At1g32930)] was found in the small compartments, of which, 45 and 40% of AtGALT29A [Arabidopsis th...

A detailed comparative map of Brassica oleracea and Arabidopsis thaliana has been established based largely on mapping of Arabidopsis ESTs in two Arabidopsis and four Brassica populations. Based on conservative criteria for inferring synteny, "one to one correspondence" between Brassica and Arabidopsis chromosomes accounted for 57% of comparative loci. Based on 186 corresponding loci detected i...

The effective management of Verticillium wilts (VW), diseases affecting many crops and caused by some species of the soil-borne fungus Verticillium, is problematic. The use of microbial antagonists to control these pathologies fits modern sustainable agriculture criteria. Pseudomonas fluorescens PICF7 is an endophytic bacterium isolated from olive roots with demonstrated ability to control VW o...

We analyzed sequence variation for chalcone synthase (Chs) and alcohol dehydrogenase (Adh) loci in 28 species in the genera Arabidopsis and Arabis and related taxa from tribe Arabideae. Chs was single-copy in nearly all taxa examined, while Adh duplications were found in several species. Phylogenies constructed from both loci confirmed that the closest relatives of Arabidopsis thaliana include ...
