Physiol. Annu Rev Plant Physiol. In addition, the activity of RuBisCO is coordinated with that of the other enzymes of the Calvin cycle in several other ways: Upon illumination of the chloroplasts, the pH of the stroma rises from 7.0 to 8.0 because of the proton (hydrogen ion, H+) gradient created across the thylakoid membrane. Differential abscisic acid regulation of guard cell slow anion channels in Arabidopsis wild-type and abi1 and abi2 mutants. In our study, 106 of 178 MYB genes were detected as responsive to heat stress. [31], In cyanobacteria, inorganic phosphate (Pi) also participates in the co-ordinated regulation of photosynthesis: Pi binds to the RuBisCO active site and to another site on the large chain where it can influence transitions between activated and less active conformations of the enzyme.
Tetrapyrrole profiling in Arabidopsis seedlings reveals that retrograde plastid nuclear signaling is not due to Mg-protoporphyrin IX accumulation. [29][30], The removal of the inhibitory RuBP, CA1P, and the other inhibitory substrate analogs by activase requires the consumption of ATP. Plant Cell 23, 3992–4012. The Arabidopsis NFYA5 transcription factor is regulated transcriptionally and posttranscriptionally to promote drought resistance. Our study presents a systematic investigation of differentially expressed genes in heat-stressed P. simonii. 149, 88–95. To balance ion potential across the membrane, magnesium ions (Mg2+) move out of the thylakoids in response, increasing the concentration of magnesium in the stroma of the chloroplasts. Combined with activities of antioxidants enzymes suggesting that efficiency of scavenging O2- and H2O2 decreased along with decreases in activities of antioxidants enzymes, leading to damage in cellular membrane after twelve hours of heat treatment. 1977, 59: 309-314. Different letters on error bars indicate significant differences at P < 0.01. 2 Biochemical pathways leading to products and processes that improve salt tolerance are likely to act additively and probably synergistically (Iyengar and Reddy, 1996).Biochemical strategies include (i) selective accumulation or exclusion of ions, (ii) control of ion uptake by ⦠[44] Advances in this area include the replacement of the tobacco enzyme with that of the purple photosynthetic bacterium Rhodospirillum rubrum. Therefore, a fundamental understanding of the response of photosynthetic physiology and related gene expression under heat stress may help to improve the thermostability of plants and limit the adverse effects of climate change on crop yield. 30600479, 30872042), Program for New Century Excellent Talents in University (No. Plants develop a plethora of biochemical and molecular mechanisms to cope with salt stress. Lines with arrowheads represent a positive effect while lines ending with a bar indicate a negative effect. In plants, algae, cyanobacteria, and phototrophic and chemoautotrophic proteobacteria, the enzyme usually consists of two types of protein subunit, called the large chain (L, about 55,000 Da) and the small chain (S, about 13,000 Da).The large-chain gene (rbcL) is encoded by the chloroplast DNA in plants. However, PGLP1 expression of the twelve and twenty-four hour treatment groups was higher than the control group after twenty-four hours of recovery, suggesting that glycollic metabolism was induced by heat stress and might be maintained for a long time.

A protein kinase-phosphatase pair interacts with an ion channel to regulate ABA signaling in plant guard cells. doi: 10.1093/nar/gkr218, Chan, K. X., Crisp, P. A., Estavillo, G. M., and Pogson, B. J. [62], With the evolution of the C4-fixation pathway in certain species of plants, C3 RuBisCO evolved to have faster turnover of CO2 in exchange for lower specificity as a result of the greater localization of CO2 from the mesophyll cells into the bundle sheath cells. These plants are called C4 plants, because the first product of carbon fixation is a 4-carbon compound (instead of a 3-carbon compound as in C3 or “normal” plants). Transcript levels are normalized to PtACTIN and error bars represent standard error. FIGURE 2.

In a related development, American scientists engineered a single gene of the RNA virus tobacco mosaic virus (TMV) into tobacco and tomato plants via the Ti plasmid vector. To confirm whether candidate genes were generally temperature-responsive, constant chilling stress (4°C, six hours) were performed. Yuepeng Song, Qingqing Chen contributed equally to this work. The molecular and physiological mechanisms ⦠(2009). Plant responses to these stresses are equally complex. Heat stress of more than twelve hours caused reduced electron transport, damaged photosystems, activated the glycolate pathway and caused H2O2 production; as a result, photosynthetic capacity did not recover completely. Trends Plant Sci. doi: 10.1104/pp.105.068254, de Lorenzo, L., Merchan, F., Laporte, P., Thompson, R., Clarke, J., Sousa, C., et al. 2007, 49: 46-63. Natl. Fifty clones were propagated from mother plant ‘QL9’. The details were according to Song et al. Over-expression of SNAC1 in plants did not produce a negative phenotype, unlike overexpression of CBF/DREB1[75]. [47] It has been also suggested that the oxygenase reaction of RuBisCO prevents CO2 depletion near its active sites and provides the maintenance of the chloroplast redox state.[48]. 1981, 32: 93-101.

10.1074/jbc.M605895200. DNA Res. These high-energy electrons drive a chemiosmotic cycle to make nicotinamide adenine dinucleotide phosphate (NADPH) and ATP. Chlorophyll intermediates, such as Mg-protoporphyrin IX (Mg-Proto), control the expression of nuclear genes in plants exposed to EL conditions, acting as a retrograde signal. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.This chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water â hence the name photosynthesis, from ⦠A comprehensive understanding on how plants respond to ⦠Functional analysis of AHK1/ATHK1 and cytokinin receptor histidine kinases in response to abscisic acid, drought, and salt stress in Arabidopsis. The retrograde signaling plays an important role in regulating the chloroplastic processes and also in the adaptive responses to environmental stresses (Chan et al., 2010). doi: 10.1016/j.cell.2012.04.038, Yamaguchi-Shinozaki, K., and Shinozaki, K. (2006). In fact, plants have evolved various molecular mechanisms to reduce their consumption of resources and adjust their growth to adapt to adverse environmental conditions (Yamaguchi-Shinozaki and Shinozaki, 2006; Ahuja et al., 2010; Skirycz and Inze, 2010; Osakabe et al., 2011; Nishiyama et al., 2013; Ha et al., 2014). 2010, 140: 163-173.

In this study, 51 HSP genes were differentially expressed in response to heat stress, 44 (86.3%) up-regulated and 7 (13.7%) down-regulated, with expression ratios ranging from 0.029 to 2677 (Figure 8 and Additional file 6). Water stress that induces a decrease in leaf water potential and in stomatal opening (Figure 1), leading to the down-regulation of photosynthesis-related genes and reduced availability of CO2, has been known as one of the major factors in the EL stress (Osakabe and Osakabe, 2012). However, after 12 h and 24 h heat stress, the photosynthetic rate recovered to only 68.8% and 45.2% of control group levels, respectively. Plant J.

Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. (2008). To characterize carbohydrate partitioning and photosynthesis in Arabidopsis thaliana we examined three different lines: wild type Columbia ecotype, immutans, and T-DNA knockouts of vacuolar acid invertase. This book is a compilation of the work being done on the applications of molecular biology and bioenergetics of photosynthesis. EL also stimulates the production of ROS, such as H2O2, superoxide (O2-) and singlet oxygen (1O2), by specific photochemical and biochemical processes, which also exerts deleterious effects on photosynthesis (Li et al., 2009). Sci. Plant Cell 11, 1743–1754. Carrillo MC, Kanai S, Sato Y, Kitani K: Age-related changes in antioxidant enzyme activities is region and organ, as well as sex, selective in the rat. Water stress directly affects rates of photosynthesis due to the decreased CO2 availability resulted from stomatal closure (Flexas et al., 2006; Chaves et al., 2009), and/or from changes in photosynthetic metabolism (Lawlor, 2002). The fourth fully expanded leaf, from each of three clones in each treatment was harvested for photosynthetic rate measurements using the portable photosynthesis system (LI-6400; Li-Cor Inc., Lincoln, NE, USA) from 18 to 24 August 2013. In our study, 165 TF genes were differentially expressed in response to high temperature (Figure 8 and Additional file 5). J. The BR-mediated alterations in the gene expressions and their roles in stress tolerance are listed in Table 2. Once again, RuBisCO activase can promote the release of these analogs from the catalytic sites and maintain the enzyme in a catalytically active form. Coloring of GO term nodes is proportional to their significance, as indicated by the scale.

Also at six hours, Ci decreased to its minimum value and iWUE increased dramatically to a peak. Utilization of this technology will make it possible to modify the regulation of key genes that will convey improved stress tolerance while maintaining productivity. In this review, we focused on the molecular mechanisms involved in the plant responses to water stress and the concomitant growth adjustment. Already, the success of molecular biology in photosynthesis has been nothing short of spectacular. Work performed over the last few years, much of which is sum marized in this volume, stands in evidence. Diagram of differentially expressed genes involved in photosynthesis. 0 h indicates the control group without high temperature treatment. RuBisCO is usually only active during the day, as ribulose 1,5-bisphosphate is not regenerated in the dark. 201204306), and the 111 Project (No. Error bars represent standard error.

This book provides an overview of the current state of the art. It is directed at researchers and professionals in plant physiology, cell biology, genetics, molecular biology and biochemistry. Expression of five HSFs expression increased, and only HSFA4C was repressed under heat stress. The conversion involves these steps: enolisation, carboxylation, hydration, C-C bond cleavage, and protonation.[13][14][15]. The Creative Commons Public Domain Dedication waiver ( 10.1007/s10059-012-2188-2. For example, MYB60, which promotes stomatal opening, increased by 5.55-fold, but MYB61, which promotes stomatal closure, did not increase (Additional file 5). The elucidation of these networks is essential to improve the stress tolerance of crops. [67], Key enzyme of the photosynthesis involved in carbon fixation. 2007, 362: 431-436. There is increasing evidence for the regulation of nuclear gene expression by 1O2 (op den Camp et al., 2003) and H2O2 (Kimura et al., 2003). This is due to the regulation of several other enzymes in the Calvin cycle. To understand the effects of high temperature on photosynthesis, we measured physiological, biochemical, chlorophyll fluorescence characters and examined changes in the transcriptome in this study. At three hours high temperature treatment, Gs and Ci decreased simultaneously, suggesting that the decreased Pn is mainly caused by stomatal conductance at this time point. We survey 141 sequenced plant genomes to elucidate consequences of gene and genome duplication, processes central to the ⦠Various environmental stresses lead to excessive production of ROS causing progressive oxidative damage and ultimately cell death.
