“…In contrast, enhanced levels of APX and MDAR were found in salt-susceptible barley roots with respect to salt-tolerant ones since salinity treatment caused larger disturbances in redox homeostasis (both ionic and toxic effects of salt) in the susceptible genotype than in the tolerant one (Witzel et al, 2009 ). Differential levels of lactoylglutathione lyase (glyoxalase) involved in detoxification of methylglyoxal as a byproduct during glycolysis and threonine biosynthesis were found in barley root (Witzel et al, 2009 ) and barley crown (Maršálová et al, 2016 ) under salinity and in oilseed rape leaves under drought (Urban et al, 2017 ). Enhanced levels of cyanate hydratase involved in degradation of cyanate, a toxic byproduct of ethylene biosynthesis, were found in a halophytic plant Suaeda aegyptiaca (Askari et al, 2006 ).…”

“…Thus, any stress treatment should be based on previous detailed review of target population of environment (Tardieu, 2012 ) and application supported by hypothesis-driven occurrence (Vadez et al, 2013 ). For example, in winter oilseed rapes, the different water-related strategy (water-savers, water-spenders) influenced significantly the rate of water uptake from the pot, and, consequently, the differential protein abundances (Urban et al, 2017 ). In the water-savers group, proteins related to nitrogen assimilation, ATP metabolism and redox homeostasis increased under stress, while in the water-spenders category, carbohydrate/energy, photosynthesis, stress related and rRNA processing proteins were increased upon stress.…”

“…An increase in enzymes such as monogalactosyl diacylglycerol (MGDG) synthase involved in the biosynthesis of thylakoid membrane glycolipids were found in maize chloroplasts at early phases of salt stress indicating alterations in thylakoid membrane composition in response to stress (Zörb et al, 2009 ). Structural proteins are also affected by stress; as an example, fibrillins as the major protein components of plastoglobuli reveal alterations in response to drought in Festuca arundinacea (Kosmala et al, 2012 ), however, in oilseed rapes, fibrillins were found significantly accumulated in all cultivars upon drought (Urban et al, 2017 ). Last, but not least, protoporhyrinogen IX oxidase was found enhanced in maize chloroplasts under salt stress (Zörb et al, 2009 ); the enzyme catalyzes a conversion of chlorophyll precursor protoporhyrinogen which is known to act as a photosensitizer involved in ROS (singlet oxygen 1 O 2 ) production under stress.…”

HIGHLIGHTS: Major environmental and genetic factors determining stress-related protein abundance are discussed.Major aspects of protein biological function including protein isoforms and PTMs, cellular localization and protein interactions are discussed.Functional diversity of protein isoforms and PTMs is discussed.Abiotic stresses reveal profound impacts on plant proteomes including alterations in protein relative abundance, cellular localization, post-transcriptional and post-translational modifications (PTMs), protein interactions with other protein partners, and, finally, protein biological functions. The main aim of the present review is to discuss the major factors determining stress-related protein accumulation and their final biological functions. A dynamics of stress response including stress acclimation to altered ambient conditions and recovery after the stress treatment is discussed. The results of proteomic studies aimed at a comparison of stress response in plant genotypes differing in stress adaptability reveal constitutively enhanced levels of several stress-related proteins (protective proteins, chaperones, ROS scavenging- and detoxification-related enzymes) in the tolerant genotypes with respect to the susceptible ones. Tolerant genotypes can efficiently adjust energy metabolism to enhanced needs during stress acclimation. Stress tolerance vs. stress susceptibility are relative terms which can reflect different stress-coping strategies depending on the given stress treatment. The role of differential protein isoforms and PTMs with respect to their biological functions in different physiological constraints (cellular compartments and interacting partners) is discussed. The importance of protein functional studies following high-throughput proteome analyses is presented in a broader context of plant biology. In summary, the manuscript tries to provide an overview of the major factors which have to be considered when interpreting data from proteomic studies on stress-treated plants.

“…This behavior was also observed in oil palms under field conditions in eastern Colombia (Bayona and Romero 2016) and in oil palm seedlings under mesh-house conditions (Silva et al 2017). When environmental conditions changed during the transition to the dry season, all cultivars showed a significant reduction in CO 2 assimilation and transpiration rate, a generalized response in many species subjected to water stress (Cruz et al, 2016;Gleason et al, 2016;Li et al, 2017;Urban et al, 2017). The cultivars evaluated showed gas exchange adjustments in response to changes in environmental factors in the short term.…”

Oil palm is the most productive and efficient oilseed crop in the world. Oil palm is planted in various geographical areas, where the frequency of extreme weather events is expected to increase because of climate change. The characterization of the response of oil palm cultivars to climatic conditions will allow identifying sources of tolerance to different types of stress caused by climate change, leading to the determination of the best genotype x environment relationships. The physiological responses, oil quality and yield of 11, six-year-old commercial oil palm cultivars with different origins were evaluated in two periods of contrasting climate conditions (rainy and dry seasons between the years 2008 and 2010). We found that the first impact of a period with water deficit was the reduction on gas exchange of all cultivars. Photosynthesis fell between 25% to 40% and transpiration decreased between 10% and 50%. During the dry season, leaf sugar concentration increased respect to the rainy season between 14% to 114%, and certain cultivars showed up to 27% higher photosynthetic water use efficiency. This variation could be due to the genetics of different cultivars. No significant differences were observed between the seasons in terms of oil quality. In general, changes in oil palm physiology observed in response to water deficit were related to the ability of the palm to adapt and survive periods of drought stress. The cultivars evaluated showed a good response to dry periods, with the IRHO being the most outstanding at each evaluated season .

“…Furthermore, at the molecular level, drought stress affects gene expression level of different pathways related to stress perception, signal transduction, regulators, and the synthesis of stress-related proteins (Kakumanu et al 2012). Proteomic changes of many plants have been studied under drought stress, including wheat (Faghani et al 2015), barley (Vítámvás et al 2015), cotton (Deeba et al 2012), tobacco (Xie et al 2016), rapeseeds (Urban et al 2016), peanut (Katam et al 2016), grapevine (Król and Weidner 2017), and maize (Benesova et al 2012, Hu et al 2011, Liu et al 2012. Studies of proteins in maize (Kakumanu et al 2012) and wheat (Caruso et al 2009) show that a very close relationship exists between drought resistance and gene expression.…”

The aim of this study was to investigate the physiological basis and molecular mechanism of genotypic variation in drought response of maize seedlings. Comparative physiological and proteomic analyses were conducted in the leaves of droughttolerant Liyu 35 (LY) and drought-sensitive Denghai 605 (DH) maize genotype seedlings. Drought induced a significant decrease of relative water content and osmotic potential of leaves, length and volume of roots, and total dry weight, but significantly increased malondialdehyde in DH seedlings. However, root dry weight , proline content and antioxidant enzyme activities increased more in LY than in DH. Forty-two spots in LY and 17 spots in DH that showed significant abundance variations were identified by matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry. These drought-responsive proteins were mainly involved in biological processes of photosynthesis, defense and oxidative stress, carbohydrate and energy metabolism, protein synthesis and processing, and cell wall biogenesis and degradation. Among them, proteins involved in defense and oxidative stress, and protein synthesis and processing were largely enriched in the LY genotype, which may contribute to a natural variation of drought resistance between LY and DH genotypes. The altered protein abundance and corresponding physiological-biochemical response shed some light on molecular mechanisms related to drought tolerance in drought-tolerant maize and provide key candidate proteins for genetic improvement of maize.
