A survey of the truffle Tuber melanosporum genome has shown the presence of 67 programmed cell death (PCD) related genes. The 67 genes are all expressed during fruit body (FB) development of T. melanosporum; their expression has been detected by DNA microarrays and qPCR. A set of fourteen PCD related genes have been chosen, those with the highest identities to the homologs of other species, for a deeper investigation. That PCD occurs during T. melanosporum development has been demonstrated by the TUNEL reaction and transmission electron microscopy. The findings of this work, in addition to the discovery of PCD related genes in the T. melanosporum genome and their expression during the differentiation and development of the fruit body (FB) would suggest that one of the PCD subroutines, may be autophagy, is involved in the FB ripening, i.e. sporogenesis.

Abstract

A survey of the truffle Tuber melanosporum genome has shown the presence of 67 programmed cell death (PCD) related genes. The 67 genes are all expressed during fruit body (FB) development of T. melanosporum; their expression has been detected by DNA microarrays and qPCR. A set of fourteen PCD related genes have been chosen, those with the highest identities to the homologs of other species, for a deeper investigation. That PCD occurs during T. melanosporum development has been demonstrated by the TUNEL reaction and transmission electron microscopy. The findings of this work, in addition to the discovery of PCD related genes in the T. melanosporum genome and their expression during the differentiation and development of the fruit body (FB) would suggest that one of the PCD subroutines, may be autophagy, is involved in the FB ripening, i.e. sporogenesis.
