“…However, a previous report on geranium indicated that low temperature decreased geraniol levels, although the precise mechanisms are unclear 74 . Phenylpropanoids form the first line of defence against abiotic stress, owing to their inherent antioxidant potential 75 . Accumulation of cinnamic acid was found to be decreased.…”

Catharanthus roseus is a commercial source for anti-cancer terpenoid indole alkaloids (TIAs: vincristine and vinblastine). Inherent levels of these TIAs are very low, hence research studies need to focus on enhancing their levels in planta. Since primary metabolism provides precursors for specialized-metabolism, elevating the former can achieve higher amounts of the latter. Cell Wall Invertase (CWIN), a key enzyme in sucrose-metabolism catalyses the breakdown of sucrose into glucose and fructose, which serve as carbon-skeleton for specialized-metabolites. Understanding CWIN regulation could unravel metabolic-engineering approaches towards enhancing the levels of TIAs in planta. Our study is the first to characterize CWIN at gene-expression level in the medicinal plant, C. roseus. The CWINs and their inter-relationship with sucrose and TIA metabolism was studied at gene and metabolite levels. It was found that sucrose-supplementation to C. roseus leaves significantly elevated the monomeric TIAs (vindoline, catharanthine) and their corresponding genes. This was further confirmed in cross-species, wherein Nicotiana benthamiana leaves transiently-overexpressing CrCWIN2 showed significant upregulation of specialized-metabolism genes: NbPAL2, Nb4CL, NbCHS, NbF3H, NbANS, NbHCT and NbG10H. The specialized metabolites- cinnamic acid, coumarin, and fisetin were significantly upregulated. Thus, the present study provides a valuable insight into metabolic-engineering approaches towards augmenting the levels of therapeutic TIAs.

“…These compounds not only act as efficient free radical scavengers but also inhibit the lipid peroxidation process and membrane stabilizers (Arora et al 2000;Michalak 2006;Verstraeten et al 2003). They also have marked ameliorative effects towards various abiotic stresses like heavy metals, chilling, osmotic stress and salinity (El-Tayeb et al 2006;El-Soud et al 2013;Li et al 2011;Singh et al 2013;Ozfidan-Konakci et al 2015;Chauhan et al 2017). Among the various class of plant phenolics, coumarin and its derivatives (Razavi 2011;Al-Amiery et al 2012;Saleh et al 2015), ferulic acid (Li et al 2013), ellagic acid (El-Soud et al 2013) etc.…”

The effect of rutin and gallic acid on growth, phytochemical and defense gene activation of rice ( L.) was investigated. The seeds of rice were primed with different concentrations of rutin and gallic acid (10-60 µg mL) to explicate the effect on germination on water agar plates. Further, to study the effect of most effective concentrations of gallic acid (60 µg mL) and rutin (50 µg mL), greenhouse pot experiment was set up to determine the changes in growth, antioxidant and defense parameters. The results revealed more pronounced effect of gallic acid on total chlorophyll and carotenoids as well as on total flavonoid content and free radical scavenging activities. Gene expression analysis of and genes involved in strengthening the plant defense further validated the results obtained from the biochemical analysis. Microscopic analysis also confirmed reduction in total reactive oxygen species, free radicals like HO and O by exogenous application of gallic acid and rutin. The data obtained thus suggest that both gallic acid and rutin can affect the growth and physiology of rice plants and therefore can be used to develop effective plant growth promoters and as substitute of biofertilizers for maximizing their use in field conditions.

“…The specific kind of bio molecule exudation by the plant will depend on the plant, microbes involved, and kind of stress. Recent research indicated that, some phenolic compounds such as cinnamic, ferulic and ellagic acids were found to enhance the plant forbearance to abiotic stresses like chilling, salinity and osmotic stress [ 4 , 5 , 6 ]. Few researches experimentally showed the role of flavonoids on stimulation of hyphal growth during early interactions between roots and mycorrhizal fungi [ 7 , 8 ].However, more information should be generated towards understanding the nonsymbiotic-plant microbe interactions, as little progress has been made in identifying the molecules responsible for attracting such rhizospheric microbes towards plants.…”

Rice Seed Priming with Picomolar Rutin Enhances Rhizospheric Bacillus subtilis CIM Colonization and Plant Growth

The effect of rutin, a bioflavonoid on the growth and biofilm formation of Bacillus subtilis strain CIM was investigated. In addition to swimming, swarming, and twitching potentials of B. subtilis CIM (BS), one picomolar (1 pM) of rutin was also observed to boost the biofilm forming ability of the bacterium. Bio-priming of rice seeds with BS and rutin not only augmented root and shoot lengths but also the photosynthetic pigments like chlorophyll and carotenoid. Similarly, high accumulation of phenolic and flavonoid contents was observed in the leaves. Fluorescent microscopic images revealed that BS plus rutin enhanced callose deposition in the leaves. It was also established that the least formation of reactive oxygen species in BS plus rutin treated rice plants was due to higher free radicals scavenging activity and total antioxidant potential. The results highlight chemo attractant nature of BS towards rutin, which by enhancing biofilm formation and root colonization indirectly strengthened the plants’ defensive state.
