Does phylogenetic analysis reveal dynamic evolution of the poly ( A ) -binding protein gene family in plants?
Expansion of the plant PABP gene family began prior to the colonization of land. By the evolution of lycophytes, the first class member whose expression is confined to reproductive tissues in higher plants had appeared. A second class member whose expression is vegetative-associated appeared in gymnosperms and all three modern classes had fully evolved by the appearance of the first known basal angiosperm. The size of each PABP class underwent further expansion during subsequent evolution, especially in the Brassicaceae, suggesting that the family is undergoing dynamic evolution.
Scalpel and electrocautery are similar in terms of early postoperative and late-term wound complications when used to perform midline abdominal incisions. Therefore, the choice of method remains a matter of the surgeon's preference.
