Cryptosporiopsis Bubák & Kabát isolates were obtained for the first time from roots of apparently healthy aspen seedlings in Alberta. These isolates were similar in all the major morphological features previously used to separate Cryptosporiopsis species, but sequencing data of the ITS1-5.8S-ITS2 region indicated that they were separated into two groups, one belonging to Cryptosporiopsis ericae Sigler and the other to Cryptosporiopsis radicicola Kowalski & Bartnik. Scanning electron microscopy of ex-type cultures and selected isolates from aspen roots revealed that C. ericae and C. radicicola differed in morphogenesis and structure of conidiomata: those of C. ericae were either synnematous or sporodochial, whereas those of C. radicicola possessed a peridium-like mycelial envelope bearing amorphous adhesive material. Phialides in the hymenium of C. radicicola were also embedded in amorphous matrix material but such material was absent in C. ericae. Microscopic examination of artificially inoculated aspen roots indicated that both species are endophytes of the host. Hyphal penetration by C. ericae was only occasional and confined to the host epidermis, whereas C. radicicola was more aggressive and its hyphal ingress extended to the cortical region.

Since 1991, researchers from approximately 45 nations have participated in eight International Conferences on Serpentine Ecology (ICSE). The ICSE conferences are coordinated by the International Serpentine Ecology Society (ISES), a formal research society whose members study geological, pedological, biological and applied aspects of ultramafic ecosystems worldwide. These conferences have provided an international forum to discuss and synthesise multidisciplinary research, and have provided opportunities for scientists in distinct fields and from different regions of the world to conduct collaborative and interdisciplinary research. The 8th ICSE was hosted by Sabah Parks in Malaysia, on the island of Borneo, and attracted the largest delegation to date, 174 participants from 31 countries. This was the first time an ICSE was held in Asia, the region that hosts some of the world’s most biodiverse ultramafic ecosystems. The presentations provided a cross-section of the current status of research in all aspects of serpentine-biota relations. In this Special Issue of Australian Journal of Botany, which encompasses two double issues (1–2 and 3–4), we have compiled a selection of papers from among the oral and poster presentations to provide insights into recent advances in geoecological and applied studies of serpentine habitats worldwide.

Myosins are a superfamily of actin-activated ATPases that, in the cytoplasm, work together with actin as molecular motors. The presence of actin in the nucleus has been known for many years. The demonstration of a nuclear isoform of a myosin, nuclear myosin I (NMI), stimulated a great deal of interest in possible intranuclear motor functions of an acto–NMI complex. NMI has been shown to be involved in transcription by RNA polymerases I and II. In both cases, NMI interacts with the respective polymerase and is critically involved in the basic process of transcription. A recent study on intranuclear long-range chromosome movement has now demonstrated a role for NMI in the translocation of chromosome regions as well. Moreover, this movement is based on an active and directed process that is facilitated by an acto–NMI complex, establishing for the first time a functional role for a motor complex consisting of actin and a myosin in the nucleus.

Affix Ordering

This special issue includes a selection of papers presented at the 2nd Vienna Workshop on Affix Order held in Vienna, Austria on June 4–5, 2009. The workshop was in honor of Wolfgang U. Dressler on the occasion of his 70th birthday. However, this special issue differs from the classical Festschrift dedicated to a renowned scholar and is ‘more special’ in two respects at least: 1) not all authors are Dressler's friends and colleagues, some of them are only indirectly related to him, through his students; and 2) since the papers were presented at a topic-oriented workshop, they are thematically uniform. In other words, this special issue is a kind of scientific genealogy in terms of affix ordering. Thus, the title Affixes and bases should be understood in two ways: literally – affixes and bases as linguistic notions, and metaphorically – affixes and bases as linguists related directly and indirectly to a prominent base: Wolfgang U. Dressler.

Aspectual Meaning

The article considers the competition of verbal aspects from a new perspective. Instead of employing the traditional method of demonstrating this phenomenon — an empirical replacement of the aspect of a verb in a phrase with the opposite — the author examines Dostoevsky’s choice between the variants found in different manuscripts of the same text. For the first time, based on a two-component theory of the semantic invariant of a verb type, the aspectual meaning of the selection of a verb aspect is revealed and, as a result of contextual analysis, an artistic interpretation of the selected type is proposed.

The results of the study of the duration of the juvenile period of indigenous Chechen willow leaf pear genotypes (Pyrus salicifolia Pall.) are given in connection with the acceleration of the breeding process and the use of selected forms in pear breeding for high precocity. The studies were carried out in 2016-2019 at OOO “Orchards of Chechnya” in accordance with the Agreement on creative cooperation with the Russian Research Institute of Fruit Crop Breeding. The work was carried out in accordance with generally accepted programs and methods. The objects of the study were one-year and two-year-old pear seedlings obtained from sowing seeds of selected dwarf and low-growing local Chechen forms of willow pear (P. salicifolia Pall.), laying fruit buds on annual growths and seedlings of Caucasian pear (P. caucasica Fed.), 20 500 pcs. of each specie. The aim of the research was to study the potential of precocity of willow pear seedlings and to reveal of selected forms with the greatest degree of this trait. Stratified seeds were sown in the sowing department of the OOO “Orchards of Chechnya” production nursery in April, 2017. The seedlings were grown according to the common technology in dryland conditions on the plot with chestnut soil. The first fl owering of plants was noted in the spring, 2019. As a result of the research, for the first time on a large number of the experimental material it was found that in the off spring of the indigenous Chechen willow leaf pear genotypes, the selection of a little more than 2% of seedlings with a very short juvenile period (2 years) was possible. They are of great interest in accelerating the breeding process and in the selection of new pear varieties with high precocity. 20 willow leaf pear genotypes were selected for the further use in breeding for high precocity and as sources of the trait of short juvenile period.

This special issue follows a conference entitled ‘Rencontres: A Gathering of Voices of the Vietnamese Diaspora’ that was held at the University of Melbourne, December 1-2 in 2016 and which sought to enable, for the first time, the titular transdiasporic rencontres or encounters between international authors of the Vietnamese diaspora. The present amalgam of previously unpublished texts written by celebrated Francophone and Anglophone authors of Vietnamese descent writing in France, New Caledonia and Australia today is the result of the intercultural exchanges that took place during that event. Literary texts by Linda Lê, Anna Moï and Thanh-Van Tran-Nhut are followed by writerly reflections on the theme of transdiasporic encounters from Hoai Huong Nguyen, Jean Vanmai and Hoa Pham. Framing and enriching these texts, scholarly contributions by established experts in the field consider the literary, cultural and linguistic transfers that characterize contemporary writing by authors of Vietnamese origin across the Francophone world. Ce volume spécial réunit les Actes du colloque ‘Rencontres : A Gathering of Voices of the Vietnamese Diaspora’ qui s’est tenue à l’Université de Melbourne les 1er et 2 décembre 2016 et qui visait à faciliter, pour la première fois, les rencontres entre les auteurs, chercheurs et universitaires internationaux de la diaspora vietnamienne. Les fruits de leurs échanges interculturels y sont réunis dans ce présent recueil sous deux formes complémentaires : d’un côté, les articles d’experts en littérature francophone comparée ; de l’autre, les contributions créatives de célèbres auteurs francophones et anglophones d’origine vietnamienne basés aujourd’hui en France, en Nouvelle Calédonie et en Australie. Les textes littéraires de Linda Lê, Anna Moï et Thanh-Van Tran-Nhut, suivis de réflexions d’auteurs par Hoai Huong Nguyen, Hoa Pham et Jean Vanmai sur le thème des rencontres transdiasporiques, se retrouvent enrichis par les études savantes menées sur les transferts littéraires, culturelles et linguistiques qui caractérisent l’écriture contemporaine des écrivains d’origine vietnamienne dans le monde francophone.
