EN: Reduced Relative Clause: The phrase 'the plant utilises for nitrogen storage' is a relative clause modifying 'amino acid'. The relative pronoun 'which' or 'that' has been omitted because it functions as the object of the verb 'utilises'.
This is the method researchers use to collect data.
EN: The use of 'utilises' instead of 'uses' is characteristic of formal scientific register in British English (note the '-ises' spelling, though '-izes' is also used in some UK contexts). It implies a functional or strategic application of a resource.
