(Go the mothers!!!) Was reading recently about the Wollomi Pine and the fascinating discovery that all the trees, in both sites, are genetically identical. Has there been any further developments in finding out why this is so? Just thought you might have some inside info.

And I assume that the genome of this plant has not been sequenced yet? Otherwise it would have been possible to design microarray chips, and perform expression studies between the offsprings of the same maternal type, i.e. offspring of maternal (A) grown in light gaps vs offspring of maternal (A) grown in understory. In this way, one can see which genes are the fitness determinants, and proceed from there to check the underlying epigenetic mechanism, as you suspect it to be.
