Expression of wFKBP77 and
wFKBP73 in tissues exposed to heat stress. Northern-blot
analysis of RNA extracted from 2- to 6-d-old etiolated and green shoots
(A), 2- to 6-d-old roots (B), anthers (Ant), and pistils (Pis) (results
of an independent experiment; see Methods) (C). RNA
was extracted only from the basal first 1 cm of the shoots and the
distal first 1 cm of the roots. Blots were hybridized with the FKBP77,
FKBP73, and 26S rRNA probes. Scale of green shoots (D) and roots (E)
represents 100% for the transcripts abundance of 2-d-old green shoots
exposed for 2 h at 37°C. Solid lines, wFKBP77; dashed lines,
wFKBP73.
