“…Enhanced acetic acid accumulation in Arabidopsis improves its drought-stress tolerance via jasmonic acid signaling [ 320 ]. Endogenous citric acid levels increase in response to various types of abiotic stress [ 321 , 322 ] and the exogenous application of citric acid appears to alleviate the negative impact of these stresses on crop growth and yield [ 323 , 324 ].…”

The vast majority of agricultural land undergoes abiotic stress that can significantly reduce agricultural yields. Understanding the mechanisms of plant defenses against stresses and putting this knowledge into practice is, therefore, an integral part of sustainable agriculture. In this review, we focus on current findings in plant resistance to four cardinal abiotic stressors—drought, heat, salinity, and low temperatures. Apart from the description of the newly discovered mechanisms of signaling and resistance to abiotic stress, this review also focuses on the importance of primary and secondary metabolites, including carbohydrates, amino acids, phenolics, and phytohormones. A meta-analysis of transcriptomic studies concerning the model plant Arabidopsis demonstrates the long-observed phenomenon that abiotic stressors induce different signals and effects at the level of gene expression, but genes whose regulation is similar under most stressors can still be traced. The analysis further reveals the transcriptional modulation of Golgi-targeted proteins in response to heat stress. Our analysis also highlights several genes that are similarly regulated under all stress conditions. These genes support the central role of phytohormones in the abiotic stress response, and the importance of some of these in plant resistance has not yet been studied. Finally, this review provides information about the response to abiotic stress in major European crop plants—wheat, sugar beet, maize, potatoes, barley, sunflowers, grapes, rapeseed, tomatoes, and apples.

“…For instance, the addition of CA to the irrigation solution of tomatoes in calcareous soils (high concentration of CaCO 3 ) improved the uptake and assimilation of Zn, Na, Ca, and N in leaves, and Mn, Na, Mg, and P in fruits [56]. Likewise, maize (Zea mays) plants grown in soil with high salinity and 100-200 ppm CA showed restored height, chlorophyll a and b contents, enhanced growth, and an improvement in yield when compared to salt-treated controls [57].…”

Reductions in crop yields brought about by abiotic stress are expected to increase as climate change, and other factors, generate harsher environmental conditions in regions traditionally used for cultivation. Although breeding and genetically modified and edited organisms have generated many varieties with greater abiotic stress tolerance, their practical use depends on lengthy processes, such as biological cycles and legal aspects. On the other hand, a non-genetic approach to improve crop yield in stress conditions involves the exogenous application of natural compounds, including plant metabolites. In this review, we examine the recent literature related to the application of different natural primary (proline, l-tryptophan, glutathione, and citric acid) and secondary (polyols, ascorbic acid, lipoic acid, glycine betaine, α-tocopherol, and melatonin) plant metabolites in improving tolerance to abiotic stress. We focus on drought, saline, heavy metal, and temperature as environmental parameters that are forecast to become more extreme or frequent as the climate continues to alter. The benefits of such applications are often evaluated by measuring their effects on metabolic, biochemical, and morphological parameters in a variety of crop plants, which usually result in improved yields when applied in greenhouse conditions or in the field. As this strategy has proven to be an effective way to raise plant tolerance to abiotic stress, we also discuss the prospect of its widespread implementation in the short term.

Seeds of Moringa oleifera were planted in sandy and vermicular soil (1/2 w/w) and irrigated with Hoagland solution. Two weeks later, the seedlings were divided into three groups: The first group was irrigated with a control solution (Hoagland solution), the second with a salt solution (10 g/l NaCl) and the third group with a mixed solution (10 g/l NaCl and 100 mM citric acid (CA)). Salinity induced a substantial inhibitory effect on seedling growth of Moringa oleifera. Salt treatment reduced shoot fresh weight (FW), the content of photosynthetic pigments and total soluble proteins (SP). Furthermore, salt treatment resulted in accumulation of total free amino acids, soluble sugars and proline. CA supply in saline solution improved shoot growth, and photosynthetic pigment and soluble proteins levels. The important content of citric acid in leaves was accompanied with a decrease of total free amino acids, soluble sugar and proline contents. More that, exogenous application of citric acid led to a decrease of Malondialdehyde (MDA) and hydrogen peroxide (H2O2) accumulation, reflecting the reduction in the imbalance situation and membrane damage induced by salt stress. Alternatively, citric acid supply in saline conditions reduced the rise of superoxidase dismutase (SOD) and catalase (CAT) activities induced under salinity. Citric acid enhanced the growth rate of salt-treated Moringa oleifera via enhancing antioxidant function. Consequently, citric acid treatment may be a promising method for improving Moringa oleifera plants’ tolerance to salt stress.
