[BioC] How to get a heatmap of a dendrogram subtree?

I have another question about heatmaps...
I would like to get a heatmap only from a part of the cluster (right
now, it is impossible to read the labels).
I got the dendrogram sub-trees using the cut function (subtrees <-
cut(cluster, h=1)). Now, before giving each subtree to heatmap, I
guess I have to select the corresponding data from the matrix (i.e.,
the probes that are included in each sub-tree), how can I get the
leaves/members of each subtree (subtrees$lower[[i]])?
or alternatively, how can I partion what is shown in a heatmap while
keeping the ordering of the cluster?
