We bring each client everything we have learned from these successees as well as from the inevitable disappointments that come with pursuing transformative change.

Now in our fourth decade, we remain committed to using what we know to give our clients their best chance to make a difference in the lives of the children and youth in their communities.

Our Mission We are a nonprofit c 3 organization dedicated to improving the lives of children, especially in underserved areas, through data-guided insight and action.

Abiotic stress tolerance is known to be a complex trait. Microarray studies revealed that at least several hundred genes are involved in response to abiotic stress in plants [33].

Many efforts have been made to increase tolerance to drought, salinity, and low temperature in Arabidopsis and other plant species by expression of stress-inducible transcription factors [34] , [35] , [36].

It was proposed that a combination of transcription factor that act in different pathways such as ROS scavenging and osmotic adaptation, may prove even more beneficial for improving stress tolerance [5].

However, progress in successful genetic engineering of salt-tolerant crops has been limited by our lack of understanding of the molecular basis of salt tolerance and limited choices of effective genes that confer salt resistance.

In some instances, transgenic plants expressing the stress-responsive genes exhibited abnormal growth and development, which adversely affected some important agronomic traits.

For example, use of the strong constitutive 35S promoter to drive overexpression of DREB1A resulted in severe growth retardation under normal growing conditions [34].

Microbial sources have recently received much attention because of their exceptionally high diversity.

It has been previously proposed that there are remarkable similarities between bacteria and plants in their cellular responses to osmotic stress, because organisms from both kingdoms accumulate the same set of cytoplasmic solutes upon exposure to conditions of hyperosmolarity.

Thus, closely parallel mechanisms likely exist in bacteria and plants to mediate responses to various stresses [38].

Efforts have been made to engineer stress-tolerant crops using microbial genes, such as bet -cluster genes encoding the choline oxidation enzymes CDH and betaine aldehyde dehydrogenase from E.

The ability of transgenic B. To our knowledge, this is the first report of salt stress tolerance attributable to expression of a bacterial global regulator in a crop plant.

IrrE is believed to function as a transcriptional regulator that is required for D. Since its identification from D.

Furthermore, purified IrrE protein does not directly bind to the promoter region of recA or other induced genes [44]. Further, the D.

Thus, it is a highly intriguing question with regard to how the IrrE protein functions in the heterologous E. In fact, similar phenomena have also been observed in pathogen-host plant interactions.

For example, plant pathogenic Pseudomonas syringae deliver bacterial virulence factor proteins into the host cell, where they function to manipulate host defense and metabolism to benefit the extracellular bacterial colony [45] , [46].

Also, Agrobacterium is well known for its ability to hijack fundamental cellular processes during the genetic transformation of its hosts.

In a recent paper, Djamei et al. In this study, we showed that expression of IrrE in E. We cannot discount the possibility that IrrE may have an as yet undiscovered role and that its expression in E.

But results from our proteome analysis favor the notion that IrrE acts as a global regulator to regulate different sets of proteins such as stress-responsive proteins, protein kinases, glycerol-degrading enzymes, detoxification proteins and growth-related proteins in E.

It is well known that salt-stress also causes oxidative damage to cells as it induces ROS accumulation and that oxidative damage protection is an important aspect of salt-stress tolerance [2].

We also observed a significant induction of several detoxification proteins in IrrE-expressing E. Quantitative RT-PCR analysis revealed that genes encoding manganese superoxide dismutase SOD were upregulated in transgenic Brassica napus plants, which also suggests the existence of similar regulatory systems of IrrE in both E.

Therefore, changes in the levels of detoxification proteins and stress-responsive genes may collectively contribute to the increased salt tolerance in these genetically modified organisms.

Further studies are required to identify its direct target genes or its interacting partners in order to elucidate the molecular mechanisms of IrrE in conferring improved salt tolerance in plants.

Our results presented here may provide new insights into the molecular basis of IrrE functions contributing to salt tolerance, and demonstrate its utility as an effective means of manipulating abiotic stress tolerance in crop plants.

Bootstrap values based on replications are listed as percentages at branching point. Bar, 0. EAN1pec, Putative uncharacterized protein.

The irrE gene was amplified from D. Brassica napus cultivar Shuanzha no. Rooted shoots were transplanted to soil and seeds T1 were collected.

Cells were then pelleted from 1 ml cultures by centrifugation to remove the growth medium before transferring to fresh LB medium in the presence or absence of 3.

Cell suspensions OD approximately 0. For heat stress, cell suspensions OD approximately 0. After incubation, serial dilutions of 10 times were made.

Ten microliters of each dilution was spotted onto LB solid plates. For growth assays under salt stress, E. Cultures were then diluted to an OD of 0.

Growth rate was monitored by absorbance change at nm. For greenhouse salt-tolerance experiments, wild-type and transgenic seeds T2 were germinated and grown in the greenhouse according to a published protocol [19].

Two weeks after germination, plants were treated with NaCl at mM for six weeks in pots, and then transferred to the field. The E. Subsequently, NaCl was added to the medium final concentration 1 M and cells were harvested after 1 h.

After centrifugation at 10, g for 10 min, cellular proteins from the supernatant were collected and cellular proteins from the pellet were solubilized.

The protein concentration was measured using the Bradford method [51]. PDQuest version 7. Proteins were identified by automated peptide mass fingerprinting using the Global Proteome Server Explorer software Applied Biosystems.

Data processing was done by iCycler real-time detection system software version 2. All real-time PCRs were performed in duplicate in three independent experiments.

Subsequently, cells were resuspended in fresh medium with or without 1. Data represent the means and standard errors of three replicate experiments.

Protein isolation from four-week-old plants was performed as described [54]. Protein content was determined by Bio-Rad assay.

Western blots of the different membrane fractions were performed as described [55]. Upregulated proteins of the E.
