“…During their evolutionary process, plants, as sessile organisms, developed an array of molecular mechanisms to adapt to the varying environments, resulting in diversified molecular phenotypes and morphological traits (e.g., flowering time, yield and organ size)31. Understanding of the molecular factors determining plant adaptation is of general significance in plant research, and of particular importance in staple crops, which depends mainly on the quantification of the relationship between phenotypic characteristics and growth habitats or genotypic characteristics.…”

Seed metabolites are critically important both for plant development and human nutrition; however, the natural variation in their levels remains poorly characterized. Here we profiled 121 metabolites in mature seeds of a wide panel Oryza sativa japonica and indica cultivars, revealing correlations between the metabolic phenotype and geographic origin of the rice seeds. Moreover, japonica and indica subspecies differed significantly not only in the relative abundances of metabolites but also in their corresponding metabolic association networks. These findings provide important insights into metabolic adaptation in rice subgroups, bridging the gap between genome and phenome, and facilitating the identification of genetic control of metabolic properties that can serve as a basis for the future improvement of rice quality via metabolic engineering.

“…Plants suffer from physiological stresses when exposed to abnormal environments such as extreme temperatures, drought, high salinity, heavy metals, and nutrient imbalance (Genga et al 2011;Savvides et al 2016). Hyperosmotic stress, cell dehydration, reactive oxygen species (ROS) overproduction, and leaf chlorosis are the main responses to such stresses (Table 1).…”

Abiotic and biotic stresses are the major factors limiting plant growth worldwide. Plants exposed to abiotic and biotic stresses often cause reduction in plant biomass as well as crop yield, resulting in plant biomass carbon loss. As a beneficial and quasiessential element, silicon accumulation in rhizosphere and plants can alleviate the unfavorable effects of the major forms of abiotic and biotic stress through several resistance mechanisms and thus increases plant biomass accumulation and crop yield. The beneficial effects of silicon on plant growth and crop yield have been widely reviewed over the last years. However, carbon accumulation of silicon-associated plant biomass under abiotic and biotic stresses has not yet been systematically addressed. This review article focuses on both the main mechanisms of silicon-mediated alleviation of abiotic and biotic stresses and their effects on plant biomass carbon accumulation in terrestrial ecosystems. The major points are the following: (1) the recovery of plant biomass via silicon mediation usually exhibits a bell-shaped response curve to abiotic stress severity and an S-shaped response curve to biotic stress severity; (2) although carbon concentration of plant biomass decreases with silicon accumulation, more than 96% of the recovered plant biomass contributes to plant biomass carbon accumulation; (3) silicon-mediated recovery generally increases plant biomass carbon by 35% and crop yield by 24%. In conclusion, silicon can improve plant growth and enhance plant biomass carbon accumulation under abiotic and biotic stresses in terrestrial ecosystems.

“…In addition to the physiological phenotypes, metabolite profiles in crops are also altered by both biotic and abiotic stresses [198,199]. Deleterious metabolites such as reactive oxygen species might be generated through the disruption of normal cellular processes while beneficial metabolites such as signaling molecules and osmoprotectants may be generated to alleviate the stress [200,201].…”

Abiotic and biotic stresses lead to massive reprogramming of different life processes and are the major limiting factors hampering crop productivity. Omics-based research platforms allow for a holistic and comprehensive survey on crop stress responses and hence may bring forth better crop improvement strategies. Since high-throughput approaches generate considerable amounts of data, bioinformatics tools will play an essential role in storing, retrieving, sharing, processing, and analyzing them. Genomic and functional genomic studies in crops still lag far behind similar studies in humans and other animals. In this review, we summarize some useful genomics and bioinformatics resources available to crop scientists. In addition, we also discuss the major challenges and advancements in the “-omics” studies, with an emphasis on their possible impacts on crop stress research and crop improvement.
