Heat shock proteins(Hsps) can relieve environmental stress damage by aiding proper folding or degradation of denatured proteins.The resurrection plant Boea hygrometrica can tolerate desiccation and revive after rehydration.In desiccated leaves of B.hygrometrica,an Hsp-coding gene was cloned and designated Bh DNAJC2.Sequence analysis revealed that Bh DNAJC2 contained a J-domain and thus was a novel member of the Hsp40 family.Real-time PCR revealed that Bh DNAJC2 was induced by dehydration,cold,heat,oxidative...
