“…However, the content of rosmarinic acid was decreased by drought stress in S. miltiorrhiza root [6]. Cao et al showed that the "sweating" process changed the accumulation of metabolites, including lipids, lipid-like molecules, phenylpropanoids, and polyketides in S. miltiorrhiza [12]. In addition, there is evidence showing that bioactive constituents (including aurantio-obtusin, aloe-emodin, rhein, and chrysophanol) in the seeds of Cassia obtusifolia were increased by moderate drought (80-50% deficit irrigation) [12].…”

Salvia miltiorrhiza Bunge (Danshen) is an important traditional Chinese medicine herb. This study aimed to investigate the drought-responsive metabolic profiling in S. miltiorrhiza using gas chromatography time-of-flight mass spectrometry (GC-TOFMS) analysis. Fifty day-old S. miltiorrhiza seedlings were treated with two (moderate drought, MD) and four weeks (high drought, HD) of withholding water. The S. miltiorrhiza leaf and root samples were prepared for the GC-TOFMS analysis. Differential metabolites with substantial changes in content in S. miltiorrhiza leaf and root were identified using multivariate and univariate statistics. A total of 178 and 157 annotated metabolites were detected in S. miltiorrhiza leaf and root, respectively. Multivariate analysis showed that significantly discriminant metabolites in S. miltiorrhiza leaf by drought were associated with “galactose metabolism” and “citrate cycle”. In addition, the significantly discriminant metabolites in S. miltiorrhiza root were associated with “starch and sucrose metabolism”. Univariate statistics showed that the content of succinic acid, d-glucose, and oxoglutaric acid in S. miltiorrhiza leaf was increased by drought (fold change, FC > 1.5). Allose, d-xylose, melibiose, mannose, sorbitol, quinic acid, sinigrin, and taurine in S. miltiorrhiza root were decreased by drought (FC < 0.67). There were different metabolic profiles between S. miltiorrhiza leaf and root. However, the influence of drought stress on the pharmacological value and accumulation of bioactive constituents in S. miltiorrhiza should be further investigated.

“…This negative correlation is because plants tend to allocate more biomass to roots preferentially when subjected to limited water and nutrient availability. [21] Interestingly, VNR-145 accumulated considerable biomass in AMF treatment while failed to accumulate the same in the absence of AMF. There is no significant effect of AMF on root biomass in VNR-314 at 60% FC [ Figure 1].…”

Introduction:Plants are persistently exposed to series of varied unfavorable conditions in natural environments. Around the world, drought is one of the major concerns negatively effecting crop yield. Decreased soil water availability has become more prevalent in several parts of the world limiting arable land for agriculture. Enhancement of drought tolerance in plants mediated by arbuscular mycorrhizal fungi (AMF) is one of the notable strategies that could be persuaded to achieve sustainable agriculture. Capsicum annuum is one of the important horticultural crops. Shallow roots render the crop more prone to water stress. This study was performed to evaluate the impact of AMF on four hot pepper cultivars in pot culture. Materials and Methods: Four cultivars of hot pepper plantlets, namely US-341, VNR-314, VNR-145, and Indam-05 were subjected to three water regimes -control (100% field capacity [FC]), moderate stress (60% FC), and severe stress (40% FC) and five treatments -control, 60% FC with AMF, 60% FC without AMF, 40% FC with AMF, and 40% FC without AMF. Plant growth attributes, namely shoot fresh weight, shoot dry weight, root fresh weight, and root dry mass were measured. Biochemical traits such as relative water content, chlorophyll content, chlorophyll stability index, and ion leakage were quantified. Results: The applied drought stress levels reduced plant growth (shoot biomass and root biomass) of mycorrhizal and non-mycorrhizal plants in comparison to control plants (100% FC). However, the association of mycorrhizal fungus with the plant stimulated growth by increasing the absorption of water from roots and maintaining the same in leaves comparing to AMF non-treated plants. Furthermore, mycorrhizal symbiosis allowed the plants to maintain membrane integrity, thereby reducing the deleterious effects of drought. Drought-stressed mycorrhizal plants showed significantly better performance than non-mycorrhizal plants. Besides, four pepper cultivars responded differently to same AMF emphasizing specific varietal sensitivity to AMF. Among the four cultivars used for the study, VNR-145 showed better performance in both mycorrhizal and non-mycorrhizal treatments. Conclusion: The results highlight that AMF alleviate drought by maintaining relatively higher water status in hot pepper plants. Furthermore, the association of Glomus coronatum AMF and C. annuum var. VNR-145 ecotype is advocated to determine the extent to which these results can be manifold under field conditions.

“…Hazrati et al (2017) reported water stress decreased plant growth and leaf yield of Aloe vera L. while caused an increase in biochemical compounds. Also, the results showed that different water availability effected on plant growth of Cassia obtusifolia L. a traditional Chinese medicinal plant (Xue et al, 2018), Mentha piperita (Rahimi et al, 2018) and Hyptis suaveolens (Arruda et al, 2018). Charles et al (1990) no changes were observed in menthol contents in plants of M. piperita under water deficit.…”

The purpose of the present work was to evaluate the vegetative growth of Mentha piperita L. cultivated under different water availability, as well its influence in content, chemical composition and in vitro antioxidant activity of its essential oil. Plants were propagated by mother plants microcutting and scions were transplanted to 5 L pots with soil and cattle manure. Afterward, were kept at field capacity for 30 days and under treatment for 40 days. It was treated with different levels of water deficit treatments: (T1): 100 of field capacity (FC); (T2): 80 of FC; (T3): 60 of FC; (T4) 40 of FC with 5 blocks. Vegetative growth was evaluated by dry matter contents of all part of plants and by root/aerial rate. The essential oil of the leaves was extracted by hydrodistillation, analyzed by GC-FID and GC-MS and in vitro antioxidant potential was evaluated. A significant decrease in the dry matter of leaves and stems accompanied with a decrease in the roots dry matter was observed with an increase in the water stress. Quantitative chemical differences were observed in the chemical composition of the essential oil, according water availability. Total antioxidant activity showed a gradual increase as water stress progressed.
