Molecular differentiation of <i>Pantoea stewartii</i> subsp. <i>indologenes</i> from subspecies <i>stewartii</i> and identification of new isolates from maize seeds

Abstract

A possible detection of P. stewartii subsp. stewartii, the causative agent of Stewart's wilt of maize, in plant material by immunological or molecular assays must exclude contamination with P. stewartii subsp. indologenes, which would create false positives in seed tests and affect quarantine measurements.
