2022, Journal of Plant PhysiologyCitation Excerpt :The concentration of four alkaloids, such as catharanthine, vindoline, vinblastine, and vincristine, increased significantly with salt stress, but total dry weight decreased slightly. Plant growth inhibition might be an adaptive response to salt stress that consumes less power while allowing the right defensive reaction to being initiated, reducing the risk of heritable harm (Jing-Yan and Zhao-Pu, 2010). Senecio aquaticus, Senecio jacobaea, and their hybrids enhanced the accumulation of pyrrolizidine alkaloids (PAs) to respond to the water scarcity stress (Kirk et al., 2010).
Effect of jasmonic acid on alkaloids content and salinity tolerance of Catharanthus roseus based on morpho-physiological evaluation
2021, South African Journal of BotanyCitation Excerpt :The findings of the present study indicated that the saline water reduced the uptake of nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) by C. roseus plants. Salinity minimizes the ability of plant to absorb essential plant nutrients, and consequently, it reduces the plant's ability to carry out important vital processes (Wang and Liu 2010; Cartmill et al. 2013; Rekaby et al. 2020; Ding et al. 2020). Various mechanisms performed by plant to cope with salt conditions including: osmoregulation, ion compartmentalization and accumulation of antioxidants (Shrivastava and Kumar 2015; Sheyhakinia et al. 2020).
Chitosan nanoparticles effectively combat salinity stress by enhancing antioxidant activity and alkaloid biosynthesis in Catharanthus roseus (L.) G. Don
2021, Plant Physiology and BiochemistryCitation Excerpt :In C. roseus, salt stress reduces herb productivity, increases the activities of antioxidant enzymes, and stimulates total alkaloid production. These processes have several protective functions (Wang and Liu, 2010; Fatima et al., 2015). Salt stress also severely affects the chlorophyll content and biomass of both leaves and stems in C. roseus (Neves et al., 2018; Lacerda et al., 2020).
