“…From the angle of individual plant development, Plant Growth Grand Periodicity curve can reflect and show the above trend [4-9,102-109,136-140]. Besides, plant responses to soil water deficits take a "slow-fast-slow" shaped curve in terms of main physio-biochemical indices change and this is in agreement with Plant Growth Grand Periodicity, which also illustrates this fact and the wide plasticity for plants [29,31,32,101,102]. Surely, concerted expression of corresponding genes in plant gene regulatory network system makes it possible that we can see the phenotype and phenotype change under given temporal-spatial condition [23,24,82,83,93,95].…”

“…It is important to remember the fact that some transcriptional elements may regulate several metabolic pathways and one metabolic pathway may need orchestrated regulation from some transcriptional elements, which is the nature of plant gene regulatory network system [7,95,96,101,102,125,126]. So, in some cases, only introducing a transcriptional element cannot obtain targeted phenotype and may lead to metabolic unbalance in plants.…”

“…Plant production realization is obtained eventually through physiological pathways at least at the level of individual and community [102][103][104][105][106][107][108][109]120,[130][131][132][133][134][135][136][137][138][139][140]. One molecule or cell cannot produce any economic effect in field [22,23,77,78,117].…”

“…Although it is accepted that diverse environmental stress factors never act alone, experimental study of plant responses to abiotic stresses is normally restricted to plant reactions on isolated stress factors [2][3][4][5][6]134,[144][145][146][147]. However, it has to be considered that stress always occurs as a complex of various interacting environmental factors that contribute in varying degrees to the overall stressed phenotype [72,73,[97][98][99][100][101][102][103][104][105][106][107][108][109]. Consequently, plants usually respond to a unique complex of growth conditions [13,16,77,78,117,[124][125][126].…”

“…Abiotic and biotic stress factors have some common signal and responding pathways in plants and thereby can be utilized potentially by cross-signaling [14,93,118,119]. Further, sessile plants have to get alone with the dynamics of changing environmental conditions and have the flexibility for responding to these complicated changes [10,11,15,16], and this has to be achieved at the various stages of plant development [23,24,37,40,47,[102][103][104][105][106][107][108][109]. Considering the interacting complexity (at least including water movement, solute transport, information exchange, ion homeostasis regulation, and other related physi-chemical changes) between plants and their surroundings, it is important to understand physiological functions for higher plants under environment.…”

Research ArticleMetabolomic Study on the Halophyte Suaeda salsa in the Yellow River Delta Plant metabolomics has been well established and applied across multiple fields including medicine, biotechnology, and environmental sciences in the post-genomic era. The Chenopodiaceae C 3 halophyte Suaeda salsa is the most important plant species in the vegetation of saline soil and even intertidal zone in the Yellow River Delta, which is economically consumed as food, widely used as a bioindicator of environmental stresses (salinity, drought, and pollution) and typically applied for the phyto-remediation of degraded wetland. However, no global studies have been focused on the metabolic profile of this halophyte which is widely applied in environment related research areas. In metabolomics, the first crucial step is the preparation of plant samples. In this work, several strategies of metabolite extraction from this C 3 halophytes S. salsa were evaluated and the metabolic profile was characterized by NMRbased metabolomics. Multiple replicates of plant tissues (approx. 250 mg whole fresh weight of leaves and stems) were homogenized by a high throughput automated Precellys 24 bead-based homogenizer and then extracted using the following solvent systems of varying polarities: methanol, water, methanol/water, methanol/chloroform/ water, and acetonitrile. The hydrophilic metabolites were analyzed using one-dimensional proton NMR spectroscopy, and the subsequent NMR spectra were evaluated by principal components analysis (PCA). Each extraction protocol revealed unique metabolic profile from S. salsa. Overall, the quality of each extraction protocol was assessed based on the yield, reproducibility, ease, and speed, and we concluded that the solvent of methanol/water was preferable for the metabolite extraction due to its highest reproducibility, ease, and speed, and considerably high yield. Validation of methanol/ water (1:1) solvent also showed a high degree of reproducibility with technical variation being considerably lower than biological variation in S. salsa samples. This demonstrated the quality and robustness of the methanol/water extraction method for NMRbased metabolomics studies.

Worldwide, crop productivity is drastically reduced by drought and salinity stresses. In order to develop food crops with increased productivity in marginal areas, it is important to first understand the nature of plant stress response mechanisms. In the past decade, proteomics tools have been extensively used in the study of plants' proteome responses under experimental conditions mimicking drought and salinity stresses. A lot of proteomic data have been generated using different experimental designs. However, the precise roles of these proteins in stress tolerance are yet to be elucidated. This review summarises the applications of proteomics in understanding the complex nature of drought and salinity stress effects on plants, particularly cereals and also highlights the usefulness of sorghum as the next logical model crop for use in understanding drought and salinity tolerance in cereals. With the vast amount of proteomic data that have been generated to date, a call for integrated efforts across the agricultural, biotechnology, and molecular biology sectors is also highlighted in an effort to translate proteomics data into increased food productivity for the world's growing population.
