Leaf senescence constitutes the last stage of leaf development in plants and proceeds through a highly regulated program in order to redistribution of micro- and macro-nutrients from the senescing leaves to the developing/growing plant organs. Initiation and progression of leaf senescence is accompanied by massive sequential alterations at various levels of leaf biology including leaf morpholog...

A GENOME-WIDE ANALYSIS OF PERFECT INVERTED REPEATS IN ARABIDOPSIS THALIANA by Sutharzan Sreeskandarajan Perfect inverted repeats play wide variety of roles in genomes. In this study, we conduct a genome-wide analysis of perfect inverted repeats in Arabidopsis thaliana and explore the biological significance of the observed inverted repeat distribution. The roles of palindromic sequences are rev...

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...
