TLDR
The cytosol of the sporangiophore of Phycomyces blakesleeanus has considerable chitinolytic activity, and the possibility is discussed that chit inase might be involved in the growth response system by transiently loosening the rigid framework of chitin at specific and defined points.About:

TL;DR: Three proteins which display chitinase activity were purified from the supernatants of Trichoderma harzianum CECT 2413 grown in minimal medium supplemented with Chitin as the sole carbon source, suggesting that each protein is encoded by a different gene.

Characterization of chitinase and chitobiase produced by the entomopathogenic fungus Metarhizium anisopliae
TL;DR: In this article, the mechanism of action of chitinolytic enzymes is discussed, and the chitinase fractions eluted from a sephadex column had activity against chitosan and chitotriose.

Roles of Chitinases in Fungal Growth
TL;DR: There are three roles for chitinases in fungi: (a) Most spectacularly, they are involved in the gross autolysis associated with the release of spores in some basidiomycete fruit bodies, (b) They have a nutritional role, (c) they have a morphogenetic role in the growth and differentiation of all Chitin-containing fungi, and (d) this has however proved the most difficult to obtain evidence for.

Light response in Phycomyces blakesleeanus: evidence for roles of chitin biosynthesis and breakdown
TL;DR: It is suggested that the light growth response in the sporangiophore from Phycomyces is due to a transient softening of thecell wall at the growing region followed by an elongation due to the turgor pressure of the cell and an enhanced chitin biosynthesis by the apically localized chit in synthetase which restores normal strength to the cell wall.

Mutants of Phycomyces with abnormal phototropism.
TL;DR: A model with a photoreceptor, early and late linear transducers, a logarithmic transducer and a growth-controlling element is proposed for the information channel of the phototropic response.

Observations on cell walls of yeasts and some other fungi by x-ray diffraction and solubility tests
TL;DR: Several new fungal cell wall components with characteristic X-ray diagrams have been detected and considered differences between the cell walls of certain yeasts and between those of certain other fungi have been established.

The Bursting Tendency of Hyphal Tips of Fungi: Presumptive Evidence for a Delicate Balance between Wall Synthesis and Wall Lysis in Apical Growth
TL;DR: Observations are offered as circumstantial evidence supporting the following conclusions: the growing tips of fungi have a large wall lytic potential and the release of this activity during growth must be gradual and delicately co-ordinated with wall synthesis; this balance can be easily disturbed by a wide variety of external stimuli and the ensuing surge of lytic activity results in the violent disintegration of the hyphal apex.
