“…Corn yield is closely related to crop evapotranspiration (ET c ) and usually yield would be lowered if ET is lowered [12]. Drought and flooding are abiotic stresses which caused crop yield decrease [21] [35]. In this concern, other investigators indicated that the furrow irrigation by gated pipes achieved the highest yields of maize [9] [36] and sugarcane [26].…”

“…More than 6% of the world's land and one third of the world's irrigated land are significantly affected by soil salinity (Flowers and Yeo, 1995;FAO, 2008). A study shows that soil salinity has affected more than 100 million hectares of agricultural land worldwide (Athar and Ashraf, 2009). Salinity effects are more prominent in arid and semiarid regions where limited rainfall, and high evapotranspiration and temperature associated with poor water and soil management (Azevedo Neto et al, 2006;Jaleel et al, 2008).…”

Proline accumulation is the main adaptive mechanism to salinity in plants. The pot experiments were carried out to mitigate the adverse effects of NaCl stress on BARI Hybrid Maize-5 and Hybrid Maize Pacific-987 by exogenous application of proline. Plants were exposed to different concentrations of NaCl at vegetative stage. Proline solutions were sprayed over maize leaves at both vegetative and tasseling stages. NaCl stress caused significant reductions in plant growth of maize. NaCl stress at 50 mM drastically reduced the growth of maize plant. Salt stress also reduced reproductive growth, grain yield, chlorophyll contents, K+/Na+ ratio and nutrient (NPS) uptake in both maize varieties. Exogenously applied proline improved growth and grain yield of BARI Hybrid Maize-5 at 25 mM NaCl stress condition. Additionally, BARI Hybrid Maize-5 conferred tolerance to 50 mM NaCl stress with 25 mM proline. Proline application significantly increased K+/Na+ ratio and nutrient uptake by maize under salt stress. The present study suggests that proline improves salt tolerance of maize by increasing the K+/Na+ ratio and nutrient uptake, particularly P uptake.Progressive Agriculture 27 (4): 409-417, 2016

“…They are the main cause of extensive agricultural production losses worldwide (Barnabas et al 2008;Athar and Ashraf 2009). Among abiotic stresses, drought, salinity and extreme temperatures are the major environmental constraints that modern agriculture has to cope with.…”

Influence of abiotic stresses on plant proteome and metabolome changes

Plant responses to abiotic stresses are very complex phenomena with individual characteristics for various species. Abiotic stresses (e.g. drought, salinity, flooding, cold, heat, UV radiation, heavy metals, etc.) strongly affect plant growth and development. It is estimated that they are the cause of more than 50 % of crop yield losses. Abiotic stresses are known to activate a multigene response resulting in the changes in various proteins and primary and secondary metabolite accumulation. Therefore, proteomic and metabolomic approaches are becoming very important and powerful tools used in studying plants' reaction to various stimuli. Precise analysis of proteome and metabolome is essential for understanding the fundamentals of stress physiology and biochemistry. In this review, we focus on recent reports concerned to the influence of abiotic stresses on changes in the level of different protein groups and metabolite classes. Basic information about physicochemical methods applied to qualitative and quantitative analyses of biopolymers and natural products is also briefly presented.
