We developed Glycine max cv MiniMax (PI643148) that has a rapid life cycle, short stature and characteristic simple sequence repeat (SSR) markers that could make it useful for mutant screening, functional genomics, genetic mapping and other studies involving soybeans. We demonstrate that MiniMax is able to make somatic embryos (SEs) that rapidly develop into plantlets. Thus, the rapid cycling habit carries over into aspects of plant regeneration. Chimaeras (having transformed roots with untransformed aerial stocks) have been produced rapidly under non-axenic conditions using Agrobacterium rhizogenes-mediated transformation. Part of these experiments involved the engineering an enhanced green fluorescent protein (eGFP) reporter cassette outside the multi-cloning site of a plant expression vector, permitting non-invasive visual screening of the transformed roots. The rapid cycling growth habit of MiniMax, its ability to efficiently generate SEs and ability to be transformed should prove useful for basic aspects of G. max molecular and genetic research.
