Rapid molecular authentication of three medicinal plant species, Cynanchum wilfordii, Cynanchum auriculatum, and Polygonum multiflorum (Fallopia multiflorum), by the development of RAPD-derived SCAR markers and multiplex-PCR

"Quina" (Strychnos pseudoquina A. St. Hil) is a medicinal plant species from the Brazilian Cerrado. As its seeds show dormancy, they were subjected to the treatments pre-cooling at 5ºC during 7 days, pre-heating at 40ºC during 7 days, pre-soaking in sulfuric acid PA during 5 and 15 min, pre-soaking in boiling water during 5 and 15 min, pre-soaking in 100 and 200 ppm gibberellic acid during 48 h, pre-soaking in distilled water during 24 and 48 h, and mechanical scarification to break dormancy. Counts were daily conducted from the 2nd day after the experiment implementation until the germination stabilization at the 65th day. The germination speed index (GSI) and the germination percentage were evaluated. Germination rates above 96% were reached in seeds pre-soaked in water during 48 h and substrate moistened with water or KNO3.

Abstract Human-induced CO2 emissions since the preindustrial era have accumulated CO2 in the atmosphere which has influenced the plant structure and function including bio-chemical constituents of the plant system. The Himalayan vegetation has been predicted to be more vulnerable and sensitive to climate change. However, it is still not well documented that how atmospheric CO2 concentration will change the biochemical constituents considering nutrients status of Himalayan endangered plants in future climate change. Hence, we examined the impacts of elevated CO2 concentrations (ambient- ~ 400, 600, and 800 µmol CO2 mol− 1) on biochemical constituents (chlorophyll, carotenoids, ascorbic acid, protein, and total sugars and carbon partitioning) and nutrients response (potassium, phosphorus, and magnesium) in leaf, stem and root tissue of Asparagus racemosus Willd. (an endangered medicinal plant species of Himalayas). The results showed that the elevated CO2 concentration significantly (p ≤ 0.05) enhanced the chlorophyll, protein, total sugars, and carbon accumulation conversely diminished ascorbic acid in leaf tissues. The nutrients accumulation especially potassium and magnesium were significantly (p ≤ 0.05) improved while phosphorus accumulation suppressed under elevated CO2 concentration. Moreover, elevated CO2 notably altered protein, sugars, carbon, and nutrients partitioning in plant tissues viz. leaf, stem, and root of A. racemosus. The fate of rising atmospheric CO2 concentrations beyond 800 µmol CO2 mol− 1 will require much more study. Further studies are needed to understand the impacts of elevated CO2 concentration as well as a combination with other associated climatic variables on biochemical response particularly bioactive ingredients/health-promoting substances and nutrient profiling of this and other endangered medicinal plant species for improving livelihood support of the society.
