Metabolic responses of the green microalga Dunaliella salina to silver nanoparticles-induced oxidative stress in the presence of salicylic acid treatment

Toxicity of Nd2WO6 nanoparticles to the microalga Dunaliella salina: synthesis of nanoparticles and investigation of their impact on microalgae

“…The results of Bahador et al on the impact of silver nanoparticles on D. salina showed that beta-carotene content increases under all concentrations of silver nanoparticles compared to the control, which indicates the response of algal cells to the presence of stressors. 33 Similar phenomena have occurred at different metal stresses in algae, suggesting that the increase in carotenoid synthesis responds to ROS suppression caused by heavy metals. 31 A direct relationship was observed between increasing nanoparticle concentration and MDA amount (Fig.…”

Grand Challenges in Microalgae Domestication

“…Dunalliella has a main haploid cycle, but sexual reproduction is known. Draft genomic data are available (Polle et al, 2017 ) and nuclear and chloroplastic transformations have been validated recently (Dehghani et al, 2017 ; Norzagaray-Valenzuela et al, 2018 ; Bahador et al, 2019 ; Song et al, 2019 ). Technically both Chlorella and Dunaliella could be amenable to intensive genetic engineering.…”

The Antifungal Activity of Ag/CHI NPs against Rhizoctonia solani Linked with Tomato Plant Health

“…Total chlorophyll content and anthocyanin level were measured on tomato plant leave after 30 days. Chlorophyll content was analyzed according to the method of [44], the pigments were extracted and grounded from 0.5 g of third fully expanded plant leaf between 8:00 and 10:00 am, suspended in 10 mL of 80% (v/v) acetone in the dark using a pestle and mortar. Extracts were filtrated and content of total Chll was determined by spectrophotometry at 645 and 663 nm.…”
