Genomic Differences Between Two Formae Speciales Causing Root Rot in Cucumber.

The host specificity of () formae speciales has been reported to be linked to effector proteins known as Secreted in Xylem (SIX). These genes are associated with the non-autonomous mobile element miniature impala (), normally distributed on the accessory chromosomes. The pattern of associated with effector genes has been used to predict candidate effector profiles which characterize formae speciales.

Synthetic Biology Approaches to Posttranslational Regulation in Plants.

To date synthetic biology approaches involving creation of functional genetic modules are used in a wide range of organisms. In plants, such approaches are used both for research in the field of functional genomics and to increase the yield of agricultural crops. Of particular interest are methods that allow controlling genetic apparatus of the plants at post-translational level, which allow reducing non-targeted effects from interference with the plant genome.

Using an RNA Aptamer to Inhibit the Action of Effector Proteins of Plant Pathogens.

In previous work, we experimentally demonstrated the possibility of using RNA aptamers to inhibit endogenous protein expression and their function within plant cells In the current work, we show that our proposed method is suitable for inhibiting the functions of exogenous, foreign proteins delivered into the plant via various mechanisms, including pathogen proteins. Stringent experimentation produced robust RNA aptamers that are able to bind to the recombinant HopU1 effector protein of bacteria. This research uses genetic engineering methods to constitutively express/transcribe HopU1 RNA aptamers in transgenic .

RNA-aptamers-As targeted inhibitors of protein functions in plants.

The scope of RNA-aptamers application is becoming wider and has expanded beyond solely medical use. We propose the use of RNA-aptamers in plants to suppress the functions of individual proteins, thereby achieving resistance to various biotic and abiotic stresses. In current work we experimentally demonstrate the possibility of inhibiting protein activity in N.

Search for Partner Proteins of Immunophilins Involved in the Control of Plant Immunity.

The involvement of plant immunophilins in multiple essential processes such as development, various ways of adapting to biotic and abiotic stresses, and photosynthesis has already been established. Previously, research has demonstrated the involvement of three immunophilin genes (, , and ) in the control of plant response to invasion by various pathogens. Current research attempts to identify host target proteins for each of the selected immunophilins.

Characterization of three Arabidopsis thaliana immunophilin genes involved in the plant defense response against Pseudomonas syringae.

Plant immunophilins are a broadly conserved family of proteins, which carry out a variety of cellular functions. In this study, we investigated three immunophilin genes involved in the Arabidopsis thaliana response to Pseudomonas syringae infection: a cytoplasmic localized AtCYP19, a cytoplasmic and nuclear localized AtCYP57, and one nucleus directed FKBP known as AtFKBP65. Arabidopsis knock-out mutations in these immunophilins result in an increased susceptibility to P.

Bacterial thermostable beta-glucanases as a tool for plant functional genomics.

A new strategy for creating experimental models for functional genomics has been proposed. It is based on the expression in transgenic plants of genes from thermophilic bacteria encoding functional analogues of plant proteins with high specific activity and thermal stability. We have validated this strategy by comparing physiological, biochemical and molecular properties of control tobacco plants and transgenic plants expressing genes of beta-glucanases with different substrate specificity.
