Exogenous biotin modulates non-stomatal photosynthetic limitation under salinity in in vitro–grown Dizygostemon riparius
This study investigates whether exogenous biotin (vitamin B7) mitigates salinity-induced physiological limitations in Dizygostemon riparius, a medicinal species endemic to Maranhão, Brazil, grown in vitro. Salinity (50 mM NaCl) significantly restricts shoot growth, reduces shoot dry mass, and decreases leaf number. Gas...
