“…Since the feeding site [Ca 2+ ] cyt elevations are attenuated, but not abolished in the tpc1-2 mutant, it appears that release of vacuolar Ca 2+ by TPC1 is downstream of and dependent on extracellular Ca 2+ release by the GLRs. This finding agrees with work showing that TPC1 activity is positively regulated by [Ca 2+ ] cyt (Hedrich and Neher, 1987;Ward and Schroeder, 1994;Allen and Sanders, 1996;Guo et al, 2016;Kintzer and Stroud, 2016) and plays a role in systemically propagating Ca 2+ -induced Ca 2+ release (Dubiella et al, 2013;Evans et al, 2016;Gilroy et al, 2016;Choi et al, 2016). Consequently, TPC1 appears to be activated by GLR-mediated Ca 2+ influx and involved in the cell-to-cell spread of Ca 2+ during biotic interactions.…”

A transient rise in cytosolic calcium ion concentration is one of the main signals used by plants in perception of their environment. The role of calcium in the detection of abiotic stress is well documented; however, its role during biotic interactions remains unclear. Here, we use a fluorescent calcium biosensor (GCaMP3) in combination with the green peach aphid (Myzus persicae) as a tool to study Arabidopsis thaliana calcium dynamics in vivo and in real time during a live biotic interaction. We demonstrate rapid and highly localized plant calcium elevations around the feeding sites of M. persicae, and by monitoring aphid feeding behavior electrophysiologically, we demonstrate that these elevations correlate with aphid probing of epidermal and mesophyll cells. Furthermore, we dissect the molecular mechanisms involved, showing that interplay between the plant defense coreceptor BRASSINOSTEROID INSENSITIVE-ASSOCIATED KINASE1 (BAK1), the plasma membrane ion channels GLUTAMATE RECEPTOR-LIKE 3.3 and 3.6 (GLR3.3 and GLR3.6), and the vacuolar ion channel TWO-PORE CHANNEL1 (TPC1) mediate these calcium elevations. Consequently, we identify a link between plant perception of biotic threats by BAK1, cellular calcium entry mediated by GLRs, and intracellular calcium release by TPC1 during a biologically relevant interaction.

“…As a second messenger in a wide range of signaling pathways, calcium connects the perception of different stimuli and stresses to their downstream cellular responses (Sanders et al, 2002 andGilroy et al, 2016). Exogenous Ca 2+ can enhance plant drought resistance and protect the structure of cellular plasma membranes (Chengbin et al, 2013).…”

“…Exogenous Ca 2+ can enhance plant drought resistance and protect the structure of cellular plasma membranes (Chengbin et al, 2013). It maintains normal photosynthesis and regulates the metabolism of plant hormones and other important chemicals (Miqyass et al, 2007 andGilroy et al, 2016). In addition, as a second messenger, cellular Ca 2+ also transmits drought signals, thus regulating the physiological responses induced by drought stress (Tuberosa et al, 2007).…”

IN THEIR natural habitats, plants are continuously subjected to many severe environmental challenges including drought. In this study, the effects of drought on Triticum aestivum seedlings were assessed, and the alleviating roles and interactive effects of calcium (Ca 2+ ) and abscisic acid (ABA) to drought stress were studied. The results showed that pretreating wheat seedlings with calcium chloride (CaCl 2 ) or ABA led to alleviating most of the negative effects of 20% polyethylene glycol (PEG, as a drought imposing agent). Ca 2+ improved the growth criteria, photosynthetic activity, but ABA had no significant effects on growth parameters. Ca 2+ or ABA pretreatments have alleviated the toxic effects of the drought-induced oxidative stress which was marked with the reduction of MDA content. Ca 2+ and/or ABA reduced the PEGinduced catalase activity, and ascorbic acid content. The use of lanthanum chloride (LaCl 3 ) as a calcium channel blocker has confirmed the role of Ca 2+ in ameliorating the drought effects on plant. This study revealed that the application of Ca 2+ has increased the endogenous ABA level of the treated seedlings to a high extent exceeding that of PEG treatment itself suggesting that ABA requires Ca 2+ ions for its induction, and ABA is working downstream from Ca 2+ in the relevant signaling pathways activated by drought stress. The alleviating effects of Ca 2+ was prolonged to the yield stage. Overall, our results suggest that Ca 2+ (10 mM), and with a less extend ABA (0.1 mM), represent signaling agents that can partially alleviate drought stress in plants growing in dry environments.

Rice (Oryza sativa) falls among the staple food crops in different parts of the globe. In current scenario of climate change, drought stress leads to significant decrease in crop production. It has negative effect on rice growth and development by affecting cellular, physiological and molecular processes. Photo-respiration increases under drought stress leads to overproduction of reactive oxygen species (ROS) in different organelles of the cell like chloroplasts, mitochondria and peroxisomes etc., which induce severe oxidative stress in rice. Over production of ROS can cause damage to proteins, lipids and DNA leading to lipid peroxidation, proteins oxidation, mutation, DNA damage that can lead to cell death. Under drought stress, ROS turn over in various organelles overload antioxidant quenching mechanism leading to oxidative damage. Oxidative stress can be overcome by the scavenging system, which consists of enzymatic and non-enzymatic antioxidants. Moreover, ROS also acts as signaling molecule and triggers defense mechanism through specific signal transduction network under stress. Under stress condition, activation of molecular cascades is initiated through the perception of stress that leads to the activation of signal transduction pathway including expression of transcription factors and stress related genes. Understanding of this regulatory mechanism of plant development and growth in drought-ROS stress can be promising in the development of improved transgenic rice under this stress. This review will provide an overview of ROS synthesis and signaling pathway under drought condition in rice.
