ABSTRACT
The remarkable ability of fungi to make tubular cells or hyphae is an exquisite case of polarized growth and has been the subject of intense attention and experimentation for more than 100 years. Much has been learned about many facets of hyphal morphogenesis, but a precise understanding of the structural, biochemical, and genetic basis of apical growth remains to be attained. In this chapter I will summarize some new developments in hyphal morphogenesis and address some of the outstanding questions in this field. Hyphal morphogenesis or tip growth of fungi has been the subject of recent reviews, each with a somewhat different perspective [1-8].
