Tuber Species

Mycorrhizal fungi of the genus Tuber are classified by morphological characters that allow differentiation of most species. However, some economically important species are difficult to differentiate on morphological grounds. When morphological traits are not sufficient to discriminate between taxa, other markers are needed. Genetic variation of fruit bodies of 12 Tuber taxa was studied by the random amplified polymorphic DNA (RAPD) technique. High interspecific variability was observed between most species. Moreover, important infraspecific variation occurred in all species, except Tuber brumale s.L, Tuber melanosporum, and Tuber magnatum. Southern hybridization patterns of RAPD products of the various species were used to confirm the data. Relationships among Tuber species were determined by cluster analyses. UPGMA analyses revealed several main clusters and a low genetic similarity between taxa. These results indicate that RAPD and polymerase chain reaction are useful for analysing genetic variation within Tuber species. Most species can be identified by differences in their amplified DNA profiles. However, the two pairs of closely related taxa Tuber aestivum – Tuber uncinatum and Tuber brumale var. brumale – Tuber brumale var. moschatum did not appear to differ genotypically. Key words: Tuber, RAPD, Southern, UPGMA, inter- and infra-specific variability.

A New Species

We describe a new species of Tuber from Yunnan Province, China, based on molecular and morphological data. This species is characterized by its snow-white ascomata, pubescent peridia and subglobose or globose ascospores. Tuber sinoniveum sp. nov. is phylogenetically closely related to T. sinosphaerosporum but differs in having ascospores with more meshes (3–9 along) and glabrous peridia. Phylogenetic placement of this novel Tuber species is in the Puberulum group.

Plastic waste can cause serious environmental problems. This can be overcome by various efforts; one of them is by replacing the use of conventional plastic with biodegradable plastic. Biodegradable plastic can be produced from tubers containing starch. The purpose of this study was to explain the suitability of two tuber species with typical protein quality and different starch structures. Starch was obtained from suweg tuber (Amorphophallus campanulatus) and ganyong (Canna edulis Ker). The material invested was obtained by dissolving 4 grams of each starch, each of which was dissolved with distilled water then added with various weight carrageenan. The tensile strength of biodegradable plastic was tested using tensile testing machines, biodegradation of soaked plastics using EM4 (Effective Microorganism) with reduced weight measurements, and Fourier Transform Infra-Red (FTIR) was used to identify the structure of compounds contained in biodegradable plastics. The tensile strength test results of biodegradable plastic from ganyong/canna tubers were 3.35 MPa with elongation of 13.51%, while the plastic from suweg tubers of 2.45 MPa with elongation was 13.68% on the addition of 5% carrageenan, respectively. Plastic degradation testing obtained plastic decomposition up to 100% in 37 days for ganyong and 34 days for suweg, respectively. It showed that the plastics was easily degraded. Identified by FTIR showed chemical structures of OH phenolic alcohols, C = O carbonyls, CO esters, NH amides and amines, and C≡C alkyne.

Sterols from ascocarps of Tuber (truffle) and Terfezia species were identified by gas–liquid chromatography, gas chromatography – mass spectrometry, and 1H nuclear magnetic resonance, and the structure of brassicasterol from the yeastlike cells of Taphrina deformans confirmed by 1H nuclear magnetic resonance. Sterols of the fruiting bodies ranged from 1.2 to 2.3 μg/mg dry weight. Ergosterol was the principal sterol of Tuber species which also contained 28–44% brassicasterol depending on the species and source of the sample. Terfezia sp., on the other hand, contained about 98% brassicasterol with only small amounts of ergosterol. Brassicasterol is common to several families of the subdivision Ascomycotina, and to our knowledge has not been reported for a nonascomycetous species.
