..We have characterized the first plant member of the HSP110/SSE1 subfamily, HSP91. At least two, tightly linked genes encoding HSP91 are present per haploid Arabidopsis genome...
Jungkunz I, Link K, Vogel F, Voll L, Sonnewald S, Sonnewald U. AtHsp70-15-deficient Arabidopsis plants are characterized by reduced growth, a constitutive cytosolic protein response and enhanced resistance to TuMV. Plant J. 2011;66:983-95 pubmed publisher
..Based on these results, AtHsp70-15 is likely to be a key factor in proper folding of cytosolic proteins, and may function as nucleotide exchange factor as proposed for yeast. ..

..Taken together, these results suggest that HTT1 mediates thermotolerance pathways because it is targeted by TAS1a, mainly activated by HsfA1a, and acts as cofactor of Hsp70-14 complexes. ..
