“…Plants respond in various ways under various environmental stress conditions (Slesak et al, 2007). Environmental stresses such as salinity, drought, flooding, high temperature inhibit the growth of plants (Öncel and Keleş, 2002;Özçubukçu et al, 2014). In our study, it was determined that there was a significant decrease in shoot growth and dry weight in wheat seedlings under stress conditions compared to control.…”

The structure of the soil deteriorates with the changing world structure and increases the stress factors for plants. Water stress causes many morphological, physiological and biochemical changes in plants; however, it causes a decrease in photosynthesis and chlorophyll content. Drought stress affects the development of the organs of the plant such as stem, shoot and leaf area, and reduces the fresh and dry biomass of the leaves. It is important to determine malondialdehyde (MDA) value, which is an indicator of oxidative stress in plants exposed to abiotic stress, and the relationship of proteins with stress tolerance. In our study, 2 different varieties (Dağdaş and Doğankent) belonging to the Triticum aestivum L. species were used. By forming 4 different groups of this wheat (1 st group; control-2 nd group; flooding-3 rd group; drought-4 th group; salinity). At the end of the 12 th day, the plants were harvested. Compared to the control group of both wheat varieties, it was observed that the development of stress factors adversely affected shoot length, shoot dry weight in groups under stress. With the effect of abiotic stresses, a decrease occurred in chlorophyll a, chlorophyll b and total chlorophyll levels; however, it was observed that chlorophyll values of Dağdaş varieties decreased more than Doğankent and this decrease was mostly at salinity stress. Additionally, MDA accumulation was mostly in drought group of Doğankent seedlings and salinity group of Dağdaş seedlings. As a result; It can be stated that Dağdaş variety is resistant to drought and salinity stress and Doğankent seedlings are more resistant to drought stress.

“…Ducula-4). the application of waterlogging and waterlogging + NO increased antioxidant enzyme activity, as well as the expression of the genes that were studied, for example, Myb2, PDPK, and SST1, specifically during the early hours of treatment, although this was higher in the wild type + NO treatment [131]. On the other hand, Chen et al (2016) have provided support to the hypothesis that NO increases waterlogging tolerance by increased adventitious root formation and endogenous NO production via the upregulation of NOS activity in Suaeda salsa L. [132].…”

Abiotic stress in plants is an increasingly common problem in agriculture, and thus, studies on plant treatments with specific compounds that may help to mitigate these effects have increased in recent years. Melatonin (MET) application and its role in mitigating the negative effects of abiotic stress in plants have become important in the last few years. MET, a derivative of tryptophan, is an important plant-related response molecule involved in the growth, development, and reproduction of plants, and the induction of different stress factors. In addition, MET plays a protective role against different abiotic stresses such as salinity, high/low temperature, high light, waterlogging, nutrient deficiency and stress combination by regulating both the enzymatic and non-enzymatic antioxidant defense systems. Moreover, MET interacts with many signaling molecules, such as reactive oxygen species (ROS) and nitric oxide (NO), and participates in a wide variety of physiological reactions. It is well known that NO produces S-nitrosylation and NO2-Tyr of important antioxidant-related proteins, with this being an important mechanism for maintaining the antioxidant capacity of the AsA/GSH cycle under nitro-oxidative conditions, as extensively reviewed here under different abiotic stress conditions. Lastly, in this review, we show the coordinated actions between NO and MET as a long-range signaling molecule, regulating many responses in plants, including plant growth and abiotic stress tolerance. Despite all the knowledge acquired over the years, there is still more to know about how MET and NO act on the tolerance of plants to abiotic stresses.

Zea nicaraguensis, a wild relative of cultivated maize (Zea mays subsp. mays), is considered to be a valuable germplasm to improve the waterlogging tolerance of cultivated maize. Use of reverse genetic-based gene cloning and function verification to discover waterlogging tolerance genes in Z. nicaraguensis is currently impractical, because little gene sequence information for Z. nicaraguensis is available in public databases. In this study, Z. nicaraguensis seedlings were subjected to simulated waterlogging stress and total RNAs were isolated from roots stressed and non-stressed controls. In total, 80 mol L -1 Illumina 100-bp paired-end reads were generated. De novo assembly of the reads generated 81 002 final non-redundant contigs, from which 5 261 full-length transcripts were identified. Among these full-length transcripts, 3 169 had at least one Gene Ontology (GO) annotation, 2 354 received cluster of orthologous groups (COG) terms, and 1 992 were assigned a Kyoto encyclopedia of genes and genomes (KEGG) Orthology number. These sequence data represent a valuable resource for identification of Z. nicaraguensis genes involved in waterlogging response.
