“…Sussman (1968) reported that melanin is important for survival of all loculoascomycetes, some pyrenomycetes and many deuteromycetes. Bell and Wheeler (1986) also observed the significance of melanin pigments in spore dormancy survival and in protection in microbial lysis in soil.…”

Sixty-seven isolates of Bipolaris sorokiniana of barley, belonging to three groups (black, white and mixed) were studied to find an association of melanin with the spore production of the fungus. Conidiogenesis in black, white and mixed subpopulation of B. sorokiniana was positively correlated with melanin content/g of mycelium. Primary hyphae of black and mixed subpopulation differentiated into secondary hyphal structures which subsequently produced conidiophores and conidia. Primary hyphae could not differentiate into secondary hyphae and subsequently conidiophores and conidia in white subpopulation. A melanin containing mutant developed from white subpopulation regained its ability to differentiate into secondary hyphae, conidiophores and conidia. Results showed that melanization of mycelia B. sorokiniana mycelia is an important factor for conidia production.

“…Because mycorrhizae are restricted to shallow depths in the soil (Oosting, 1958), sclerotia are near-surface phenomena. They remain viable for up to 14 years after formation (Sussman, 1973), sending out hyphae when conditions become favorable for growth. Sclerotia in high-altitude Front Range soils vary from 0.2 to almost 2.0 mm in maximum dimension (Figure 11).…”

Rethinking the fourth of July Valley site: A study in glacial and periglacial geoarchaeology

The Fourth of July Valley site (5BL120) occupies the crest and inner slope of a Satanta Peak (latest Pleistocene) terminal moraine above timberline in the Indian Peaks Wilderness Area, Colorado Front Range. Excavations in 1971 suggested that a Late Paleo-Indian lithic tradition marked by lanceolate and stemmed projectile points with parallel-oblique flaking persisted at high altitude during the Altithermal, long after its disappearance from drought-susceptible lowlands. Analysis of a sediment column collected in 2001 casts doubt on this interpretation. Large charred sclerotia (the resting stages of mycorrhizal fungi) show that tree islands colonized the moraine soon after deglaciation, fueling Early and Middle Holocene wildfires. Conditions became increasingly periglacial ca. 3340 yr B.P., when a lobate rock glacier advanced to the south margin of the site, altering snow-accumulation patterns, eliminating trees, supplying meltwater that fueled ice-lens formation, and initiating deposition of humusrich, snowbed loess. Large waste flakes and artifacts were frost-sorted to the existing ground surface, where they became mixed with 6240-year-old wildfire charcoal in a pseudo-occupation layer. Microflakes were too small to participate in vertical frost sorting, so remained in their original stratigraphic locations. The association of thermally altered microflakes with 8920-year-old charcoal in a deeply buried stratigraphic context suggests that the site was occupied during the Early Holocene and is irrelevant to the Altithermal refugium hypothesis.

Cloning of Sal1, a scytalone dehydratase gene involved in melanin biosynthesis in Cochliobolus heterostrophus

A melanin biosynthetic gene, Sal1, in the southern corn leaf blight fungus Cochliobolus heterostrophus, was identified by degenerate and inverse PCR. Structural analysis revealed that the open reading frame is 555 bp in length, interrupted by one intron. Melanin deficiency of the sal1 mutant strain, which accumulates the intermediate scytalone, was successfully complemented by introducing the gene fragment. These results suggest that Sal1 is a scytalone dehydratase gene of C. heterostrophus.
