“…AREB/ ABF belong to the bZIP family plant TFs known to function in ABA signaling during dehydration and seed maturation. In response to ABA, an activated AREB/ABF binds to a cis-element known as an ABA-responsive element (ABRE) to trigger gene expression (Pandey et al 2011). Up to now, participation of this kind of TFs in ABAmediated stress signaling has been described for different plants such as Arabidopsis thaliana, rice, wheat and barley (Yang et al 2010).…”

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.

“…Tomato ( Solanum lycopersicum L.) is the second most widely cultivated vegetable crop after potatoes that is extensively consumed worldwide [ 21 ]. It is considered a natural medicine with multiple health benefits for humans because it contains a significant proportion of vitamins, essential amino acids, sugars, minerals, dietary fibers, and antioxidants that prevent—or reduce the opportunities of—different cancer diseases [ 22 ].…”

Melatonin “N-Acetyl-5-methoxytryptamine” (MT) has recently been considered as a new plant growth regulator with multiple physiological functions. Although many previous studies have confirmed that exogenous applied-MT can alleviate the deleterious effects of drought stress in many plant species, most of these studies were exclusive on seeds, seedlings, and young plants for a short period of their life cycles. Therefore, the knowledge of using MT as a potential promising agricultural foliar application to improve crop productivity and quality is still insufficient under adverse open field conditions. In this study, we investigated the effect of MT as a foliar application at 0, 20, and 40 ppm on tomato plants that were grown in the open field under the long term of optimal and deficit irrigation conditions. The results indicated that exogenous MT significantly enhanced plant growth, chlorophyll and activities of antioxidant enzymes, including ascorbate peroxidase (APX), catalase (CAT), and peroxidase (POX). This improvement was associated with a marked reduction in proline and soluble sugars. In addition, applied-MT worked as a protective agent against oxidative damage by reducing the cellular content of toxic substances such as H2O2 and malondialdehyde (MDA). Similarly, MT-treated plants showed greater total fruit yield with improving its quality attributes like total soluble solids (TSS), ascorbic acid, and lycopene. Generally, the highest significant fruit yield either under well-watered (13.7%) or water deficit (37.4%) conditions was achieved by the treatment of 20 ppm MT. These results indicate that exogenous MT played an essential role in enhancing tomato tolerance to deficit irrigation and could be recommended as a promising agricultural treatment under such conditions.

“…Increasing the stress resistance of pear will improve its production and quality (Chang et al 2012b). However, studies on plant stress resistance have focused on crops including Arabidopsis, tomato and barley (Jakab et al 2005;Jiang et al 2012;Pandey et al 2011;Visioni et al 2013). Understanding the expression patterns of some key genes in the stress tolerance pathway of the pear would give insight into the mechanisms that underlie the processes from germination to harvest, and may help to reveal the changes in gene expression under various conditions.…”

RT-qPCR is a widely used method in gene expression and transcriptome studies. Normalization based on reference genes is necessary to accurately analyze RTqPCR data. Thus, an accurate and systematic evaluation of these reference genes before experiments are conducted is necessary. In this study, 18 candidate reference genes were evaluated under various experimental conditions covering a range of tissue types and cultivars, NaCl, CaCl 2 and temperature treatments, hormones (6-BA, ABA and NAA) and a set of osmotic stress (mannitol and PEG6000) treatments. Gene expression across 48 pear samples was evaluated using geNorm, NormFinder and BestKeeper statistical algorithms. Actin2/7 (ACT2/7), ubiquitin extension protein (UBI) and Yellow-leaf-specific gene 8 (YLS8) exhibited the most stable expression across all the pear samples tested. While in the other experimental groups, different sets of samples had their own best reference genes. In addition, the gene expression of PbCBL7, a member of the calcineurin B-like protein, was measured across all the 48 samples using the best three reference genes, it displayed variation in gene expression across different tissues and cultivars, and exhibited diverse up-or down-regulated expression patterns under various treatments, which indicate that PbCBL7 may play a role in response to specific abiotic stress in pear. These results are valuable for future research on gene expression and abiotic stress tolerance in pear.
