Effects of soil nutrients and microbe symbiosis on the nutrient assimilation rates, growth carbon cost and phytochemicals in Mucuna pruriens (L.) DC

Original language description

Mucuna pruriens is a legume with high nitrogen (N) fixing efficiency which makes it an ideal plant for soil N inputs/enrichment in nutrient-poor ecosystems. The current study investigated how soil nutrient availability and microbe symbiosis influence the nutrient assimilation rates, growth carbon (C) cost and phytochemicals in Mucuna pruriens under greenhouse conditions. We collected soils from four sites (namely: Ashburton, Bergville, Hluhluwe and Izingolweni) in KwaZulu-Natal (KZN) province which was used as natural inoculum and growth substrate for Mucuna pruriens seeds. Mucuna pruriens established symbiotic interactions with 18 bacterial accessions from five genera which were dominated by Burkholderia, Bacillus and Paenibacillus. Hluhluwe soil-grown Mucuna pruriens had the highest concentrations of nitrogen (approximate to 1.6 mmol) and phosphorus (approximate to 50 mmol) as well as specific nitrogen and phosphorus absorption rate. Conversely, the specific nitrogen and phosphorus utilisation rate was highest in Izingolweni soil-grown plants. In terms of nitrogen source, Mucuna pruriens derived a significant portion (68-86%) from the atmosphere. Hluhluwe soil-grown seedlings had the lowest (0.006 mmol C g(-1) DW) C cost and the highest (0.03 g day(-1)) relative growth rate. A total of nine phenolic acids consisting of hydroxybenzoic and hydroxycinnamic derivatives were quantified in the plants. Protocatechuic (approximate to 4-11 mu g g(-1) DW), caffeic (approximate to 3-17 mu g g(-1) DW), 4-coumaric (approximate to 2-17 mu g g(-1) DW) and ferulic (approximate to 2-13 mu g g(-1) DW) acids were the most abundant phenolic acids in Mucuna pruriens. The current findings demonstrated that Mucuna pruriens possibly establish symbiosis with different bacteria genera and synthesize different concentrations of phenolic acids when grown in grassland and savannah ecosystem nutrient-poor soils.
