“…Differential expression of miR159, miR167, miR1122, miR1125, miR1135, mir1136, miR1139, and miR408 was also observed under Pi deprivation in wheat (Zhao et al 2013). Among these, miR159, miR167, and miR408 have orthologues from several dicot plants.…”

“…Under these conditions, plants adapt their metabolism to P-limited conditions via regulation of several phosphate-responsive genes at both the transcriptional and translational levels (Kuo and Chiou 2011). miRNAs that show altered expression in response to P deficiency in the Triticeae have been identified in several studies (Hackenberg et al 2013a; Zhao et al 2013; Hackenberg et al 2013b). P starvation-responsive miRNA, miR399, was found to be upregulated in both barley and wheat (Zhao et al 2013; Hackenberg et al 2013b) (Table 3).…”

The continued growth in world population necessitates increases in both the quantity and quality of agricultural production. Triticeae members, particularly wheat and barley, make an important contribution to world food reserves by providing rich sources of carbohydrate and protein. These crops are grown over diverse production environments that are characterized by a range of environmental or abiotic stresses. Abiotic stresses such as drought, heat, salinity, or nutrient deficiencies and toxicities cause large yield losses resulting in economic and environmental damage. The negative effects of abiotic stresses have increased at an alarming rate in recent years and are predicted to further deteriorate due to climate change, land degradation, and declining water supply. New technologies have provided an important tool with great potential for improving crop tolerance to the abiotic stresses: microRNAs (miRNAs). miRNAs are small regulators of gene expression that act on many different molecular and biochemical processes such as development, environmental adaptation, and stress tolerance. miRNAs can act at both the transcriptional and post-transcriptional levels, although post-transcriptional regulation is the most common in plants where miRNAs can inhibit the translation of their mRNA targets via complementary binding and cleavage. To date, expression of several miRNA families such as miR156, miR159, and miR398 has been detected as responsive to environmental conditions to regulate stress-associated molecular mechanisms individually and/or together with their various miRNA partners. Manipulation of these miRNAs and their targets may pave the way to improve crop performance under several abiotic stresses. Here, we summarize the current status of our knowledge on abiotic stress-associated miRNAs in members of the Triticeae tribe, specifically in wheat and barley, and the miRNA-based regulatory mechanisms triggered by stress conditions. Exploration of further miRNA families together with their functions under stress will improve our knowledge and provide opportunities to enhance plant performance to help us meet global food demand.

“…The remaining miRNAs found unique upon glyphosate treatment, including miR159, miR166, miR167, miR169 and miR396 were also shown to be differentially expressed under Pi starvation in Arabidopsis, wheat, maize, soybean and white lupin (Lundmark et al 2010;Pei et al 2013;Zeng et al 2010;Zhao et al 2013;Zhu et al 2010). …”

Expression of miRNAs involved in phosphate homeostasis and senescence is altered in glyphosate-treated maize

et al. 2015

Glyphosate is a systemic, nonselective and most widely used herbicide in the world. The introduction of glyphosate-resistant crops in the mid-1990s resulted in a dramatic increase in the use of glyphosate herbicide making it most widely used herbicide in the world. The average maize yield loss in the field caused by pests is around 20 % but in many regions it is much higher. It is now clear that glyphosate causes broader range of physiological alterations than previously assumed and some plants gain higher level of resistance to glyphosate without the need to use genetic engineering methods. To understand the mechanisms of such heightened resistance we must first know the processes mediating the plants' death in response to glyphosate treatment. Here, we show that 12 miRNAs, belonging to miR167, miR396, miR159, miR156, miR169, miR444 and miR827 families, are significantly upregulated, and one, miR166, downregulated following glyphosate treatment. These miRNAs have been previously shown to be involved in abiotic stress responses and implicated in senescence. Strikingly, two of the induced miRNAs, miR444 and miR827, have been shown to regulate phosphate transport pathways, which seem to be common for Pi and glyphosate uptake.

“…The importance of phosphorus in maintaining soil fertility and improving crop productivity has now been recognized much more than before in view of the fact that about 66 % of Indian soils are known to give universal response to P application and remaining 34 % to heavy feeding crops [1]. Phosphorus deficiency is a limiting factor of crop production in agricultural soils worldwide [2][3][4]. Correcting P deficiency with application of P fertilizers is not possible for the resource-poor farmers in the tropics and subtropics, especially on soil with high P fixing capacity.…”

A solution culture experiment was conducted to investigate the effect of solution phosphorus concentration on the exudation of citrate and oxalate ions by five different varieties of the wheat (Triticum aestivum L). Wheat varieties were grown in a modified Hoagland nutrient solution containing five phosphorus levels (0, 0.2, 0.3, 0.4 and 0.5 lg/mL). Increasing the concentration of P significantly decreased oxalic acid exuded from roots. The exudation of oxalic acid was maximum at 10 days time interval. All the varieties of wheat were equally effective in exudating oxalic acid. The time interval had no significant effect on P concentration in plants. But significant interactive effect on plant P was found between varieties and different time intervals.
