The researchers compared the biochemical properties of two types of Cajanus plants: wild Cajanus scarabaeoides and cultivated Cajanus cajan. They found that C. scarabaeoides has more genetic diversity and may carry genes for resisting different stresses. The study showed that the two species have different leaf isoperoxidases and C. scarabaeoides has higher levels of amino acids, sugar, and protein. This suggests that C. scarabaeoides is important for its genetic diversity and potential benefits compared to the commonly grown C. cajan.
