“…Additionally, GSTs are abundant proteins encoded by a highly divergent gene family and have protective functions such as the detoxification of herbicides and the reduction of organic H2O2 during oxidative stress. As observed in previous studies, GSTs are induced by drought stress in maize (Hu et al 2011, Liu et al 2012, wheat (Caruso et al 2009, Faghani et al 2015, and rice (Lee et al 2007). Other studies, however, showed that GSTs are reduced under drought stress in poplar roots (Plomion et al 2006).…”

“…Furthermore, at the molecular level, drought stress affects gene expression level of different pathways related to stress perception, signal transduction, regulators, and the synthesis of stress-related proteins (Kakumanu et al 2012). Proteomic changes of many plants have been studied under drought stress, including wheat (Faghani et al 2015), barley (Vítámvás et al 2015), cotton (Deeba et al 2012), tobacco (Xie et al 2016), rapeseeds (Urban et al 2016), peanut (Katam et al 2016), grapevine (Król and Weidner 2017), and maize (Benesova et al 2012, Hu et al 2011, Liu et al 2012. Studies of proteins in maize (Kakumanu et al 2012) and wheat (Caruso et al 2009) show that a very close relationship exists between drought resistance and gene expression.…”

The aim of this study was to investigate the physiological basis and molecular mechanism of genotypic variation in drought response of maize seedlings. Comparative physiological and proteomic analyses were conducted in the leaves of droughttolerant Liyu 35 (LY) and drought-sensitive Denghai 605 (DH) maize genotype seedlings. Drought induced a significant decrease of relative water content and osmotic potential of leaves, length and volume of roots, and total dry weight, but significantly increased malondialdehyde in DH seedlings. However, root dry weight , proline content and antioxidant enzyme activities increased more in LY than in DH. Forty-two spots in LY and 17 spots in DH that showed significant abundance variations were identified by matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry. These drought-responsive proteins were mainly involved in biological processes of photosynthesis, defense and oxidative stress, carbohydrate and energy metabolism, protein synthesis and processing, and cell wall biogenesis and degradation. Among them, proteins involved in defense and oxidative stress, and protein synthesis and processing were largely enriched in the LY genotype, which may contribute to a natural variation of drought resistance between LY and DH genotypes. The altered protein abundance and corresponding physiological-biochemical response shed some light on molecular mechanisms related to drought tolerance in drought-tolerant maize and provide key candidate proteins for genetic improvement of maize.

“…The major functional category of proteins identified (40%) was related to disease/defense, as observed in a previous study conducted to identify proteins regulated by ABA (abscisic acid) in response to combined drought and heat stress in maize roots; the authors characterized 26.3% of the proteins as fitting into this category, which were highly abundant (Liu et al, 2013). The identified proteins could not be linked to genetic modification because seven spots were from transgenic maize flour and five from its counterpart.…”

“…An overview of major abiotic and biotic stresses threatening maize production. (Liu et al, 2013) (continued) Huang et al (2012) analyzed the desiccation tolerance of maize seeds using 2-DE combined with MS/MS. The differentially expressed proteins (e.g., 17.4 kDa Class I HSP3, EMB564, and stress responsive protein) that they observed may be involved in drought tolerance during embryogenesis and germination.…”

Maize originated in the highlands of Mexico approximately 8700 years ago and is one of the most commonly grown cereal crops worldwide, followed by wheat and rice. Abiotic stresses (primarily drought, salinity, and high and low temperatures), together with biotic stresses (primarily fungi, viruses, and pests), negatively affect maize growth, development, and eventually production. To understand the response of maize to abiotic and biotic stresses and its mechanism of stress tolerance, high-throughput omics approaches have been used in maize stress studies. Integrated omics approaches are crucial for dissecting the temporal and spatial systemlevel changes that occur in maize under various stresses. In this comprehensive analysis, we review the primary types of stresses that threaten sustainable maize production; underscore the recent advances in maize stress omics, especially proteomics; and discuss the opportunities, challenges, and future directions of maize stress omics, with a view to sustainable food production. The knowledge gained from studying maize stress omics is instrumental for improving maize to cope with various stresses and to meet the food demands of the exponentially growing global population. Omics systems science offers actionable potential solutions for sustainable food production, and we present maize as a notable case study.
