“…The work has centered on the terrestrial red/brown colored green alga Trentepohlia (Chaetophorales) which, similar to lichens, is commonly found growing on a variety of hard substrates including stone, concrete, glass, asbestos, and wood (Rindi and Guiry 2002). It usually grows in the open and shows a significant predilection for vertical surfaces such as wooden power poles, fence posts and battens, tree bark, walls, rock outcrops, and painted masonry where it often indicates the moister polar aspect (Rindi and Guiry 2003).…”

Extreme isotopic depletion of nitrogen in New Zealand lithophytes and epiphytes; the result of diffusive uptake of atmospheric ammonia?

et al. 2005

Several lichens and the terrestrial alga Trentepohlia were found to have extremely depleted 15N signatures at two sites near the Rotorua geothermal area, New Zealand. Values, typically -20 per thousand, with several extreme cases of -24 per thousand, are more isotopically depleted than any previously quoted delta15N signature for vegetation growing in natural environments. For Trentepohlia, distance from a geothermal source did not affect isotopic signature. A 100-km transect showed that the phenomenon is widespread and the discrimination is not related to substrate N, or to elevation. Rainfall NHx and atmospheric gaseous NH3 (NH3(g)) were shown to be isotopically depleted in the range -1 per thousand to -8 per thousand and could not, of themselves, be responsible for the plant values obtained. A simulation of Trentepohlia thallus was created using an acidified fiberglass mat and was allowed to absorb NH3(g) from the atmosphere. Mats exposed at the geothermal sites and on farm-land showed a significant further depletion of 15N to -17 per thousand. We hypothesize that the extreme isotopic depletion is due to dual fractionation: firstly by the volatilization of NH3(g) from aqueous sources into the atmosphere; secondly by the diffusive assimilation of that NH3(g) into vegetation. We further hypothesize that lithophytes, epiphytes, and higher plants, growing on strongly N-limited substrates, will show this phenomenon more or less, depending on the proportion of diffusively assimilated NH3(g) utilized as a N source. Many of the isotopically depleted delta15N signatures in vegetation, previously reported in the literature, especially epiphytes, may be due to this form of uptake depending on the concentration of atmospheric NH3(g), and the degree of reliance on that form of N.

“…Stomatochroon Palm, 1934, lives in the substomatal chambers of its host and was described as an "obligate endophyte (parasite)" by Chapman and Good (1983) and a commensal organism by Timpano and Pearlmutter (1983). Phycopeltis Millardet, 1870, andPhysolinum Printz, 1921, are supracuticular epiphytes but may be found on other surfaces under very humid or moist conditions (Thompson and Wujek 1992, Davis and Rands 1993, Rindi and Guiry 2002. The free-living algae Trentepohlia Martius, 1817, and Printzina Thompson & Wujek, 1992, occur widely on living and nonliving substrates (Chapman 1984, Rindi and Guiry 2002, Thompson and Wujek 1992.…”

Plant-Parasitic Algae (Chlorophyta: Trentepohliales) in American Samoa

A survey conducted between June 2000 and May 2002 on the island of Tutuila, American Samoa, recorded filamentous green algae of the order Trentepohliales (CWorophyta) and their plant hosts. Putative pathogenicity of the parasitic genus Cephaleuros and its lichenized state, Strig;ula, was also investigated. Three genera and nine species were identified: Cephaleuros (five spp.), Phycopeltis (two spp.), and Stomatochroon (two spp.). A widely distributed species of Trentepohlia was not classified. These algae occurred on 146 plant species and cultivars in 101 genera and 48 families; 90% of the hosts were dicotyledonous plants. Cephaleuros spp. have aroused worldwide curiosity, confusion, and concern for over a century. Their hyphaelike filaments, sporangiophores, and associated plant damage have led unsuspecting plant pathologists to misidentify them as fungi, and some phycologists question their parasitic ability. Of the five species of Cephaleuros identified, C. virescens was the most prevalent, followed by C. parasiticus. Leaf tissue beneath thalli of Cephaleuros spp. on 124 different hosts was dissected with a scalpel and depth of necrosis evaluated using a fourpoint scale. No injury was observed beneath thalli on 6% of the hosts, but fullthickness necrosis occurred on leaves of 43% of hosts. Tissue damage beneath nonlichenized Cephaleuros thalli was equal to or greater than damage beneath lichenized thalli (Strig;ula elegans). In spite of moderate to severe leaf necrosis caused by Cephaleuros spp., damage was usually confined to older leaves near the base of plants. Unhealthy, crowded, poorly maintained plants tended to have the highest percentage of leaf surface area affected by TrentepoWiales. Parasitic algae currently are not a problem in American Samoa because few crops are affected and premature leaf abscission or stem dieback rarely occur.PREVIOUS REPORTS of plant-parasitic algae in American Samoa were limited to an unidentified species of Cephaleuros Kunze in Fries, 1827, on mango (Mangifera indica L.), guava (Psidium g;uajava L.), and avocado (Persea americana Mill.) (McKenzie 1996). Cephaleuros is a member of the Trentepohliales, a unique order of filamentous green algae I

“…Many studies have been carried out on Trentepohlia spp., most of them focused mainly on taxonomy (Lopez-Bautista et al 2006;Rindi and Lopez-Bautista 2007;Rindi et al 2009), ecology (Rindi and Guiry 2002;Rindi and Lopez-Bautista 2007;Liu et al 2012;Allali et al 2013), and physiological characteristics (Abe et al 1999;Chapman et al 2001;Gupta and Agrawal 2004;Mukherjee et al 2010). Only a few attempts have been made to culture Trentepohlia odorata (F.H.…”

The aerial filamentous microalga, Trentepohlia arborum (Chlorophyta), was cultured in three habitats -an aerial, a subaerial and an aquatic one -using different types of bioreactors. The growth, carotenoid productivity, and morphologic differences of T. arborum in different habitats were investigated. The maximum specific growth rate (μ) of the alga obtained in the logarithmic phase in the subaerial habitat was 0.034 h −1 . HPLC analysis also demonstrated that T. arborum accumulated a high content of carotenoids. Zeaxanthin was the primary carotenoid in subaerial culture, while β,β-carotene was dominant in aerial culture. The maximum carotenoid productivity, 67.7 mg m −2 day −1 , was reached when T. arborum was cultured in the subaerial habitat under nitrogen depletion using a novel attached cultivation bioreactor. Overall, it was demonstrated that T. arborum exhibited a relatively high growth rate and carotenoid productivity under attached cultivation.
