Stress caused by drought and salinity may compromise growth and productivity of olive (Olea europaea L.) tree crops. Several studies have reported the use of beneficial rhizobacteria to alleviate symptoms produced by these stresses, which is attributed in some cases to the activity of 1-aminocyclopropane-1-carboxylic acid deaminase (ACD). A collection of beneficial olive rhizobacteria was in vitro screened for ACD activity. Pseudomonas sp. PICF6 displayed this phenotype and sequencing of its genome confirmed the presence of an acdS gene. In contrast, the well-known root endophyte and biocontrol agent Pseudomonas simiae PICF7 was defective in ACD activity, even though the presence of an ACD-coding gene was earlier predicted in its genome. In this study, an unidentified deaminase was confirmed instead. Greenhouse experiments with olive ‘Picual’ plants inoculated either with PICF6 or PICF7, or co-inoculated with both strains, and subjected to drought or salt stress were carried out. Several physiological and biochemical parameters increased in stressed plants (i.e., stomatal conductance and flavonoids content), regardless of whether or not they were previously bacterized. Results showed that neither PICF6 (ACD positive) nor PICF7 (ACD negative) lessened the negative effects caused by the abiotic stresses tested, at least under our experimental conditions.

The frequency of damage due to poisoning with chemicals is increasing. Chemical burns are the most common pathology of the esophagus in children. As a result of penetration of alkalis and contact with the wall of the esophagus, along with necrosis, damage to the mucous membrane, submucosal and muscular membrane of the esophagus occurs. Despite a large number of drugs that have been tested in the treatment of complications caused by esophageal burns, there is little information that would indicate the high effectiveness of the previously used drugs. When treating chemical burns of the esophagus there are many complications. Full restoration of the functional status of immunity is an important step in the complex therapy of treatment of chemical burns of the esophagus. The analysis of literature data shows the positive influence of polyphenols of natural origin on the normalization of physiological and biochemical parameters in various pathologies. The extract of common beans (Phaseolus vulgaris pods extract (PVPE)) is an example of a rich bioactive component of the source with beneficial characteristics for humans. Therefore, the purpose of our work was to investigate the level of proinflammatory cytokines (IL-1β and IL-6) in blood serum of rats in the simulation of alkaline esophageal burns of 2 degrees at 7th,15th, 21st and 31st days and for the introduction of Phaseolus Vulgaris pod extract. During our study, it was found that during alkali burns esophagus second degree, marked and prolonged increase in marker proinflammatory cytokines IL-1β and IL-6, which could cause the formation of granulated tissue, resulting in the formation of scars, violation of reparative regeneration and delayed healing of burn wounds. The content of proinflammatory cytokines in a group of animals with treatment is lower compared with the group with burns without treatment during the experiment time, which may indicate the expressed therapeutic effect of the extract of beans pods in alkaline burns of the esophagus.

Poplar clone Kranti was selected to assess the morphological, physiological and biochemical responses under drought at different levels of water stress, as it is a common clone used to be grown in Uttarakhand for making paper and plywood. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological and biochemical parameters related with drought tolerance were recorded. Alterations in physiological (i.e. decrease in relative water content) and biochemical parameters (i.e. increase in proline and soluble sugar content and build-up of malondialdehyde by-products) occurred in all the three levels of water stress, although drought represented the major determinant. Drought treatments (75%, 50% and 25% FC) decreased plant height, radial stem diameter, harvest index, total biomass content and RWC in all the three watering regimes compared to control (100% FC). Biochemical parameters like proline, soluble sugar and MDA content increased with severity and duration of stress, which helped plants to survive under severe stress. It was analyzed that for better wood yield poplar seedlings should avail either optimum amount of water (amount nearly equal to field capacity of soil) or maximum withdrawal up to 75% of field capacity up to seedling establishment period (60 days). Furthermore, this study manifested that acclimation to drought stress is related with the rapidity, severity, and duration of the drought event of the poplar species.
