“…Water deficit is one of the major limiting factors for crop production, and several studies have been performed to verify its effect on tomato growth, yield, secondary metabolite production, and gene expression (Nuruddin et al, 2003;Sánchez-Rodríguez et al, 2011;Giannakoula and Ilias, 2013;Sacco et al, 2013). Previous work also studied the relationship between tomato and AM fungi under WS (Dell'Amico et al, 2002;Subramanian et al, 2006;Aroca et al, 2008;Wang et al, 2014;Ruiz-Lozano et al, 2016).…”

Arbuscular mycorrhizal (AM) fungi, which form symbioses with the roots of the most important crop species, are usually considered biofertilizers, whose exploitation could represent a promising avenue for the development in the future of a more sustainable next-generation agriculture. The best understood function in symbiosis is an improvement in plant mineral nutrient acquisition, as exchange for carbon compounds derived from the photosynthetic process: this can enhance host growth and tolerance to environmental stresses, such as water stress (WS). However, physiological and molecular mechanisms occurring in arbuscular mycorrhiza-colonized plants and directly involved in the mitigation of WS effects need to be further investigated. The main goal of this work is to verify the potential impact of AM symbiosis on the plant response to WS. To this aim, the effect of two AM fungi (Funneliformis mosseae and Rhizophagus intraradices) on tomato (Solanum lycopersicum) under the WS condition was studied. A combined approach, involving ecophysiological, morphometric, biochemical, and molecular analyses, has been used to highlight the mechanisms involved in plant response to WS during AM symbiosis. Gene expression analyses focused on a set of target genes putatively involved in the plant response to drought, and in parallel, we considered the expression changes induced by the imposed stress on a group of fungal genes playing a key role in the water-transport process. Taken together, the results show that AM symbiosis positively affects the tolerance to WS in tomato, with a different plant response depending on the AM fungi species involved.

“…Water stress was reported to generate cell-damaging oxidants, but it also resulted in synthesizing a large amount of flavonoids and phenolic acids in wheat leaves [7]. Sánchez-Rodríguez et al [32] found a high increase of kaempferol and quercetin in drought-resistant tomato cultivars, while these flavonoids were reduced in drought sensitive cultivars. Some phenylpropanoid compounds were identified in maize under drought, in which p-coumaric acid and caffeic acid contents showed a build up, whereas ferulic acid quantity trended towards a lower decrease in water-stressed plants [33].…”

Abstract:In this study, responses of rice under drought stress correlating with changes in chemical compositions were examined. Among 20 studied rice cultivars, Q8 was the most tolerant, whereas Q2 was the most susceptible to drought. Total phenols, total flavonoids, and antioxidant activities, and their accumulation in water deficit conditions were proportional to drought resistance levels of rice. In detail, total phenols and total flavonoids in Q8 (65.3 mg gallic acid equivalent (GAE) and 37.8 mg rutin equivalent (RE) were significantly higher than Q2 (33.9 mg GAE/g and 27.4 mg RE/g, respectively) in both control and drought stress groups. Similarly, the antioxidant activities including DPPH radical scavenging, β-carotene bleaching, and lipid peroxidation inhibition in Q8 were also higher than in Q2, and markedly increased in drought stress. In general, contents of individual phenolic acids in Q8 were higher than Q2, and they were significantly increased in drought stress to much greater extents than in Q2. However, p-hydroxybenzoic acid was found uniquely in Q8 cultivars. In addition, only vanillic acid was found in water deficit stress in both drought resistant and susceptible rice, suggesting that this phenolic acid, together with p-hydroxybenzoic acid, may play a key role in drought-tolerance mechanisms of rice. The use of vanillic acid and p-hyroxybenzoic acid, and their derivatives, may be useful to protect rice production against water shortage stress.

“…The significant differences between the cultivars was expected, considering that it comes from plant materials which have different phenotypic characteristics. The difference between the collection periods (dry and rainy) for flavonoids and phenolic compounds in tomato cultivars (Solanum lycopersicum) was reported by Sánchez-Rodríguez et al (2011, 2012. The total phenolic compounds in tomato cultivars are higher in period rainy, while total flavonoid are superior in period dry, corroborating with the results found in this work.…”

The prickly pear is a cactaceae that have chemical compounds that act as natural antioxidants. In addition, the prickly pear is a plant widely used in semiarid region as it's considered very important forage for animal feed, especially in the dry season. The objectives of this research were to characterize the main classes of phytochemicals, determine the phenols content, flavonoids and anthocyanins and evaluate the antioxidant activity of the prickly pear cultivars Opuntia and Nopalea grown in the semiarid region of Pernambuco in two collection periods (dry and rainy). In the work crude ethanol extracts from cladodes of cultivars (IPA-20, Elephant Ear Mexican, F-08, V-19, Small palm, F-21 and IPA-Sertânia) were used. As for the class of phytochemical compounds from ethanol extract only the flavonoids and steroids were detected in all prickly pear cultivars, in both periods analyzed. The content of phenolic compounds ranges from 1.24 to 5.41 mg GAE g -1 DM, flavonoids 0.90 to 3.43 mg QE g -1 DM, anthocyanins from 0.05 to 0.34 µg QE 100 g -1 DM and antioxidant activity 39.59 to 217.17 µM TEAC g -1 DM. The occurrence of chemical variability and antioxidant activity were observed, both among the botanical cultivars studied and among the collection periods.Keywords: biodiversity and nutrition; cactus pear; flavonoids; phenolic acids; phytochemicals.Practical Application: Use of cladodes of prickly pear cultivars as functional foods in the diet human and animal.
