The Catalytic properties of hybrid Rubisco comprising tobacco small and sunflower large subunits mirror the kinetically equivalent source rubiscos and can support tobacco growth 1[W][OA]
Plastomic replacement of the tobacco (Nicotiana tabacum) Rubisco large subunit gene (rbcL) with that from sunflower (Helianthus annuus; rbcLS) produced tobaccoRst transformants that produced a hybrid Rubisco consisting of sunflower large and tobacco small subunits (LsSt). The tobaccoRst plants required CO2 (0.5% v/v) supplementation to grow autotrophically from seed despite the substrate saturated carboxylation rate, Km, for CO2 and CO2/O2 selectivity of the LsSt enzyme mirroring the...[Show more]
