“…By evaluating the colonization potential of fluorescent-labelled bacteria, we introduced an intermediate step between the laboratory and the field scale. Indeed, root colonization is a crucial event in the establishment of beneficial interactions between symbiotic and non-symbiotic (mutualist) bacteria and the plant host (Drogue et al 2012). By advanced microscopy analysis, it was previously demonstrated that the desert soil isolate Saccharothrix algeriensis is able to establish within 10 days on the root surface of grapevine plants (Compant et al 2013).…”

“…There is debate on how the origin of the plant host affects the bacteria's ability to induce beneficial effects in other plant species (Drogue et al 2012). PsJN, a Burkholderia phytofirmans strain and a well-assessed PGP grapevine endophyte, efficiently ameliorated the effects of drought on growth, physiology and yields of maize in a field trial (Naveed et al 2014).…”

Root-associated bacteria promote grapevine growth: from the laboratory to the field

Background and Aims Laboratory and greenhouse experiments have shown that root-associated bacteria have beneficial effects on grapevine growth; however, these effects have not been tested in the field. Here, we aimed to demonstrate whether bacteria of different geographical origins derived from different crop plants can colonize grapevine to gain a beneficial outcome for the plant leading to promote growth at the field scale. Methods To link the ecological functions of bacteria to the promotion of plant growth, we sorted fifteen bacterial strains from a larger isolate collection to study in vitro Plant Growth Promoting (PGP) traits. We analysed the ability of these strains to colonise the root tissues of grapevine and Arabidopsis using greenfluorescent-protein-labelled strain derivatives and a cultivation independent approach. We assessed the ability of two subsets randomly chosen from the 15 selected strains to promote grapevine growth in two field-scale experiments in north and central Italy over two years. Parameters of plant vigour were measured during the vegetative season in de novo grafted vine cuttings and adult productive plants inoculated with the bacterial strains. Results Beneficial bacteria rapidly and intimately colonized the rhizoplane and the root system of grapevine. In the field, plants inoculated with bacteria isolated from grapevine roots out-performed untreated plants. In both the tested vineyards, bacteria-promotion effects largely rely in the formation of an extended epigeal system endowed of longer shoots with larger diameters and more nodes than non-inoculated plants.Conclusions PGP bacteria isolated in the laboratory can be successfully used to promote growth of grapevines in the field. The resulting larger canopy potentially increased the photosynthetic surface of the grapevine, promoting growth.

“…to act as the carbon source for the synthesis of polysaccharide. According to Drogue et al (2012), sugar in specific bacterial lipopolysaccharide was involved in plant-microbes colonisation and attachment. This is a crucial source in creating a system of plant-microbes symbiosis between the in vitro oil palm cultures and bacterial cell.…”

“…While sugar is the main energy provider in plant tissue culture during cell growth as the carbon sources, it is also involved in many metabolic and signalling pathways for plants (Martin et al, 2000;Bolouri-Moghaddam and Van den Ende, 2012). The importance of amino acids, proteins, phenolics and sugars as a cell metabolism regulator, has significant impacts on plant-microbes interaction towards colonisation via bacterial chemotaxis, motility and plant developmental processes (Steenhoudt and Vanderleyden, 2000;Drogue et al, 2012).…”

“…First, rhizosphere bacteria must survive and compete in the root environment where extensive competition for nutrients and space occurs (Kuzyakov & Xu, 2013;Lopez-Guerrero et al, 2013). Then, rhizobacteria must display a chemotactic response towards root exudates to reach the root surface of their host plant, to which they usually adhere via a process referred to as root colonization, and overcome plant defence responses (Drogue et al, 2012). Finally, an effective interaction can take place leading to enhanced plant growth (symbiosis), plant protection against pathogens (biocontrol) or plant disease (pathogenesis).…”

Bacterial hybrid histidine kinases in plant–bacteria interactions

Two-component signal transduction systems are essential for many bacteria to maintain homeostasis and adapt to environmental changes. Two-component signal transduction systems typically involve a membrane-bound histidine kinase that senses stimuli, autophosphorylates in the transmitter region and then transfers the phosphoryl group to the receiver domain of a cytoplasmic response regulator that mediates appropriate changes in bacterial physiology. Although usually found on distinct proteins, the transmitter and receiver modules are sometimes fused into a so-called hybrid histidine kinase (HyHK). Such structure results in multiple phosphate transfers that are believed to provide extra-fine-tuning mechanisms and more regulatory checkpoints than classical phosphotransfers. HyHK-based regulation may be crucial for finely tuning gene expression in a heterogeneous environment such as the rhizosphere, where intricate plant-bacteria interactions occur. In this review, we focus on roles fulfilled by bacterial HyHKs in plant-associated bacteria, providing recent findings on the mechanistic of their signalling properties. Recent insights into understanding additive regulatory properties fulfilled by the tethered receiver domain of HyHKs are also addressed.
