Plants have developed molecular and physiological strategies to cope through abiotic stress. Plant Ubiquitin-Proteasome System (UPS) is one of the key players controlling protein turnover and is critical for immediate cellular responses during environmental stress. This research subject is Arabidopsis Plant U-box 41 (AtPUB41), a stress modulated E3 ubiquitin ligase. ​

​In this study we investigated the physiological mechanism of plants’ competition at the root level under salinity stress. Our goal is to elucidate the plants response to stress based on their carbon allocation.

​Survival of plant species in natural environment occurs by the dispersion of seeds. In our study we investigate the effect of salinity (S), short episodes of high temperature (HS) and combination of S+HS (SHS), at the reproductive phase, on yield with a special focus on the properties of dead pericarps of Brassica juncea. ​

Soils irrigate with salty water need to be flushed to remove the excess salts. This practice is limited due to the distribution of the soil solution in cavities where water is stagnant and solute transport is governed by diffusion. Salt leaching by flushing occurs in relatively short time scales, as it relies on advection dominant transport. Consequently, adsorbed ions and diffusive sites weakly participate in these short-duration rapid-flowing events. The main objective of our research is to introduce pressure-waves in the water flow regime during the leaching process for increasing the mobilization of excess salts from the root zone.​

​This study investigates how abiotic stresses impact the progeny's seed properties. In details, we sought to investigate the effect of salinity (S), short episodes of high temperature (HS), and combination of S+HS (SHS), at the reproductive phase, on the properties of dead pericarps of Brassica juncea.​

​This research aimed to investigate the response of the three different grapevine rootstock cultivars (Paulsen, Richter 110 and SO4) to salinity stress. ​

​This research focuses on the effects of salinity and nitrogen stresses on different tomato rootstock. Field and greenhouses experiment were performed using aeroponic and hydroponic systems. The overall objectives were to evaluate plants' physiological and morphological tolerance mechanisms.​

The goal of this research is to find genes that regulate agronomically important traits like various water and salinity stress coping mechanisms in plants. This requires an understanding of both the specific locations in the genome control a phenotype, and the genetic architecture of a trait. The main objective is to find novel associations between traits and genetic markers linked to them through a genome-wide association study (GWAS) on plants grown in two environmental conditions and sampled in two light regiments (mid-day and mid-night, thus catching the full range of metabolic regulation) using several hundred tomato accessions. ​

This research focuses on Sarcoconia species, halophytes used as fresh and processed food and cultivated for their highly nutritious oilseed used also in medicine. The objective of our study was to investigate some Sarcocornia ecotypes growth performance under different salinity and nitrogen levels. ​

​The ability of plants to adapt to extreme environmental conditions such as salinity is linked the production of the phytohormone Abscisic acid (ABA), the primary regulator in response to abiotic stresses. In this research we studied factors affecting the stability of the ABI4 protein in Arabidopsis plants, especially NaCl, using transgenic lines that overexpressed ABI4-eGFP driven by a constitutive highly expressed CaMV 35S promoter.​

​This research focuses on the combined abiotic stresses of salinity and drought on grapevines (Vitis vinifera). Our objectives are to investigate the physiological mechanism of abiotic  stresses tolerance on different rootstocks grafted with the same scion and the role of leaf age on salinity tolerance mechanisms. ​

In this research we aim to explore the interaction between physiological and metabolic responses in different tomato plants grafted combinations, under cold and salt stress combinations, eventually evaluating part of the metabolic pathway which is reflected by the performance of physiological parameters.​

​Plant growth and development can be regulated by manipulating root volume and fruit load intensity. In this research we investigated how root volumes and fruits loads affect physiological and morphological responses of tomato plants under salt stress.

ruit thinning is a common practice to achieve high quality fruits. In this study, the interplay of tomato shoots and roots under different salinity levels and different fruit load intensities was examined to estimate higher yield potential.​

Grafting is demonstrated as a promising tool to broaden the tolerance to abiotic stresses for tomato cultivars.  In this research it was explored the interaction between physiological and metabolic responses in different tomato plants grafted combinations, under cold and salt stress combinations. The rootstocks of the three cultivars (Lurka, 604 and 20) and Lurka grafted as the scion were examined. ​

​Salinity has been a major concern in treated wastewater (TWW) used for irrigation due to the addition of Na from desalinated water. The relatively high concentration of sodium may induce clay dispersion, aggregate slacking and decrease the saturated hydraulic conductivity of the soil. The main objective of this research is to quantify the effect of water quality perturbation occurred by desalination-derived wastewater when introduced to the well-established chemical equilibrium that prevails in long term wastewater irrigated soils. ​
