“…Plant stomata closure is in association with the increasing of foliar abscisic acid (ABA) under flooding stress. However, the inhibitive effects of ethylene on ABA-induced stomatal closure were reported by Tanaka et al (2005) and She and Song (2012). In our study, lower ASA content tomato lines L0994 and ASVEG-6 showed increasing SC after flooding treatment, whereas higher ASA content tomato L6138 showed no increasing SC after flooding treatment.…”

Tomato yields are reduced under waterlogging and high temperature stress condition. Ascorbic acid (ASA) was shown to be involved in tolerance to waterlogging and heat stresses in tomato. Among 44 wild tomato lines treated with waterlogging at 38°C, L6138 (Solanum peruvianum) showed highest ASA, shoot growth, chlorophyll content and chlorophyll fluorescence in comparison to other tomato lines. Further leaf proteins in L6138 and L0994 under waterlogging at 38°C for 72 h were analyzed by two-dimensional protein fractionation system. Different protein peaks were analyzed by comparative proteomic analysis and database searching. Fifty protein peaks expressed in response to stress treatment were identified, among which 27 proteins from L0994 and 17 proteins from L6138 were successfully sequenced. Differentially proteins expressed have major functions in protein structure maintenance, metabolism, secretion, translation, biosynthesis, signal transduction, degradation, and photosynthesis under stress. ASA might be played a role in tolerance to waterlogging and heat stress by maintaining RNA transcription, protein structure, and metabolism. In this study, we utilized a physiological and proteomic approach to discover the changes in protein expression profiles of tomatoes in response to heat and flood stresses.

“…Moreover, previous studies suggested that the decrease of leaf water content leads to the increase of ABA content to induce stomatal closure by regulating K + and anions channels (Jiang et al 2014, Kurepin et al 2015, Ha et al 2016, Brodribb and McAdam 2017. However, ethylene had a negative effect on stomatal closure induced by ABA (She and Song 2012, Chen et al 2013, Pedersen et al 2017, Najeeb et al 2018.…”

The objectives of the present study were to compare the dynamic of the growth and photosynthetic characteristics of cotton varieties contrasting in waterlogging (WL) tolerance when subjected to hypoxia stress. The growth of the WL-sensitive genotypes was notably inhibited by WL, mainly as a result of a significant reduction in the net photosynthesis (PN) after two days of hypoxia treatment; in the tolerant varieties, no significant changes in PN were observed until 8 d after hypoxia onset. The intercellular CO2 concentration and maximal photochemical efficiency of PSII significantly declined, and the nonphotochemical quenching increased in the sensitive varieties. Infrared thermography showed that a low stomatal conductance resulted in an increased leaf temperature under hypoxia stress. Spectral image analysis suggested that the pigment content and water content rapidly decreased in the leaves of the sensitive varieties. It is concluded that maintaining stomatal opening through the interaction of ethylene and abscisic acid may be an important strategy to improve waterlogging tolerance in cotton.Additional key words: chlorophyll fluorescence; Gossypium hirsutum; hyperspectral image; infrared thermal image.

“…It should be noted that, although ABA promotes ROS production in non-seed tissues, this hormone suppresses ROS production in imbibed seeds [74,75]. ABA treatment induced ⋅NO production in guard cells, mediated by nitrate reductase and a ⋅NO synthase-like enzyme [76,77,78,79]. Furthermore, ABA treatment caused sustainable increases of calcium ions (Ca 2+ ) in Commelina communis and Arabidopsis guard cells [80].…”

Photosynthesis, pathogen infection, and plant defense are three important biological processes that have been investigated separately for decades. Photosynthesis generates ATP, NADPH, and carbohydrates. These resources are utilized for the synthesis of many important compounds, such as primary metabolites, defense-related hormones abscisic acid, ethylene, jasmonic acid, and salicylic acid, and antimicrobial compounds. In plants and algae, photosynthesis and key steps in the synthesis of defense-related hormones occur in chloroplasts. In addition, chloroplasts are major generators of reactive oxygen species and nitric oxide, and a site for calcium signaling. These signaling molecules are essential to plant defense as well. All plants grown naturally are attacked by pathogens. Bacterial pathogens enter host tissues through natural openings or wounds. Upon invasion, bacterial pathogens utilize a combination of different virulence factors to suppress host defense and promote pathogenicity. On the other hand, plants have developed elaborate defense mechanisms to protect themselves from pathogen infections. This review summarizes recent discoveries on defensive roles of signaling molecules made by plants (primarily in their chloroplasts), counteracting roles of chloroplast-targeted effectors and phytotoxins elicited by bacterial pathogens, and how all these molecules crosstalk and regulate photosynthesis, pathogen infection, and plant defense, using chloroplasts as a major battlefield.
