Another strategy to increase the level of drought and salinity tolerance in plants consists of a transfer of genes encoding different types of proteins involved in molecular responses to abiotic stress such as osmoprotectants, chaperones, detoxifying enzymes, transcription factors, signal transduction proteins (kinases and phosphatases) and heat-shock proteins (HSPs) Mishra et al 2012;Li et al 2013). It is known Plant Cell Tiss Organ Cult (2015) 120:881-902 887 that the mitogen-activated protein kinases are involved in tolerance-related signaling networks associated with various stressors, including drought stress.…”

“…The sverproduction of SlAREB in transgenic tomato plants regulated genes AtRD29A, AtCOR47, and SlCI-like dehydrin under ABA and abiotic stress treatments. Mishra et al (2012) inserted the transcription factor gene ATHB-7 (Arabidopsis thaliana homeodomain-leucine zipper class I genes) into the tomato genome. ATHB-7 gene is induced in plants under drought stress via a mechanism that requires the production of ABA and acts as a negative growth regulator in Arabidopsis the expression of A. thaliana transcription factor gene ATHB-7 in tomato plants significantly reduced the leaf stomatal density and stomatal pore size, which is probably crucial in preserving higher water potential.…”

Originating in the Andes, the tomato (Solanum lycopersicum L.) was imported to Europe in the 16th century. At present, it is an important crop plant cultivated all over the world, and its production and consumption continue to increase. This popular vegetable is known as a major source of important nutrients including lycopene, bcarotene, flavonoids and vitamin C as well as hydroxycinnamic acid derivatives. Since the discovery that lycopene has anti-oxidative, anti-cancer properties, interest in tomatoes has grown rapidly. The development of genetic engineering tools and plant biotechnology has opened great opportunities for engineering tomato plants. This review presents examples of successful tissue culture and genetically modified tomatoes which resistance to a range of environmental stresses improved, along with fruit quality. Additionally, a successful molecular farming model was established.

“…In chloroplasts, heat stress generally reduces the photochemical efficiency of photosystem II (PS II), an important component of photosynthesis (Reynolds et al, 1994;Al-Khatib and Paulsen, 1999). The extent of change in PS II indicated by chlorophyll fluorescence, which refers to the ratio of variable fluorescence to maximum fluorescence (Fv/ Fm), and the base fluorescence (F 0 ) is a physiological parameter that was correlated with heat tolerance (Moffat et al, 1990;Rekika et al, 1997;Mishra et al, 2012). In view of the changing scenario of the environmental condition, there is a dire need to develop genotypes that are either tolerant to terminal heat stress or that mature early without yield losses and thus escape the stress.…”

Cell membrane stability, grain filling rate, grain filling duration, canopy temperature and grain yield were used to evaluate performance of 100 diverse bread wheat (Triticum aestivum L.) genotypes under timely sown and late sown heat stress conditions for two cropping season. The genotypes differed significantly for all the traits showing considerable variation for improvement of characters. The genotypes WH1165 had significant high grain yield (14.6* g and 11.4g) and (11.3* g and 11.4* g) followed by cell membrane stability under timely sown and heat stress conditions, respectively indicating potential tolerance against heat stress. Correlation coefficients revealed that cell membrane stability (0.451**) and (0.639**) in timely sown and in late sown conditions, respectively were the most important trait followed by grain filling rate (0.882** and 0.744**) under timely sown and late sown conditions respectively. Results revealed that bread wheat genotypes which had high value of cell membrane stability had high grain yield showed potential photorespiration and high grain filling rate under heat stress condition. Twenty two genotypes WH1021, WH1155, VL803, WH787, NW1014, Raj3765, HD1869, 2042, WH1124, HD2285, WH1133, HUW234, 4066, Sonak, UP2425, UP2473, PBW503, PBW373, PBW533, SGP13, HD2643 and WH789 were identified as heat tolerant genotypes based on their relative performance in yield components, grain yield and heat susceptibility indices. These genotypes were found to be ideal candidates to be used in developing heat tolerant wheat varieties. Canopy temperature, membrane thermostability and grain filling rate have also shown strong correlation with grain yield. Because of this association, these traits constitute the best available 'tool' for genetic improvement of wheat suitable for cultivation under heat stressed environments. Thus, these could be used as indirect selection criteria for developing heat tolerant wheat genotypes that would provide sufficient yields to meet the ever increasing wheat demand.

“…Overall, our results suggested that stay green maize had higher photosynthetic capability than non-stay green maize under drought conditions. Chlorophyll fluorescence has been noted as a critical indicator of photosynthetic performance in plants (Zhang, 1999) and was widely utilized for determining the performance and viability of plants in response to drought (e.g., Faraloni et al, 2011;Mishra et al, 2012). In our study, Fv/Fm, qL and ETR were decreased under .83** ABA, abscisic acid; ZR, zeatin riboside; Chl, chlorophyll content; Pn, photosynthetic rate; Gs, stomatal conductance; Fo, PS-II original fluorescence; Fv/Fm, maximal PS-II photochemical efficiency; qL, photochemical quenching; ETR, electron transport rate **, significant at 0.01 probability level; *, significant at 0.05 probability level drought stress, indicating that drought stress inhibited the photochemical activity of PS II (Fig.…”

Stay green, a characteristic of delaying leaf senescence, is desirable for maintaining photosynthetic activities, particularly under drought conditions. This study investigated the endogenous abscisic acid (ABA) and cytokinin (CTK) in maize plants and their potential relations with photosynthetic activities during late growth stage under drought stress. Two maize inbred lines, including stay green inbred line (Dan598) and non-stay green inbred line (Huangzao4), were planted in pots. Plants were treated with non-drought stress (75-80% of the field moisture capacity) and drought stress (45-50% of the field moisture capacity), which were maintained by using soil moisture sensor at anthesis or grain filling stage, respectively. The green leaf area per plant, chlorophyll contents (Chl), photosynthetic rate (Pn), and stomatal conductance (Gs) of Huangzao4 decreased more considerably compared to those of Dan598 under drought stress. Maize plants with stay green had greater photosynthetic performance than non-stay green under drought conditions. In addition, chlorophyll fluorescence parameters including maximal photochemical efficiency (Fv/Fm), photochemical quenching (qL), and electron transport rate (ETR) of both maize inbred lines had the same decreasing trend as compared to their respective Pn. Drought reduced photosystem Ⅱ (PSⅡ) original fluorescence (Fo) in Dan598 but increased Fo in Huangzao4. Drought stress had substantially increased ABA but reduced zeatin riboside (ZR) contents in the leaves and roots. Moreover, ABA content was negatively correlated with Pn, while ZR and ZR/ABA were positively correlated with Chl, Pn, Gs, Fv/Fm, qL, and ETR. Overall, the results suggested that both ABA and CTK were involved in controlling photosynthetic performance, and greater photosynthetic activity of stay green maize could be attributed to higher ZR and ZR/ABA when subjected to drought.
