Identification of mRNAs encoding low molecular mass heat-shock proteins in maize (Zea mays L.)

Subjecting 5-day-old maize seedlings to a rapid elevation in growth temperature (heat shock; 25–42 °C) results in a shift in the pattern of protein synthesis in maize plumules from the production of a broad spectrum of proteins to the new and (or) enhanced synthesis of a small number of heat-shock proteins (HSPs). The low relative molecular mass (M r ) HSPs, and more specifically an 18-kDa HSP with four major isoelectric variants, represent the...
