Abstract

Methionine and threonine are two essential amino acids belonging to the aspartate-derived family of amino acids. In plants, they both originate from the same precursor, O-phosphohomoserine (OPH) (Fig. 1). This contrasts with the situation seen in bacteria where branching between the two pathways occurs upstream of OPH, at the level of homoserine (Saint-Girons et al, 1998). Despite intensive studies (for reviews, see Giovanelli et al., 1980; Leustek, 1996; Azevedo et al., 1997; Hell, 1997; Ravanel, 1997; Ravanel et al., 1998b), the specific mechanisms that are responsible for homeostatic regulation of methionine and threonine in plants are not fully understood.
