Response To Temperature

A worldwide collection of 60 isolates of Pythium ultimum and 37 asexual (sexually sterile) isolates presumed to be P. ultimum were compared by isozyme analysis, morphological characters, and their growth rate at different temperatures. Isolates were separated into 10 multilocus genotypes as defined by nine isozyme loci. Five genotypes (U1–U5) comprising 85 isolates differed from each other merely by homo- or hetero-zygous states at one and (or) two loci. Four isolates in genotype U6 produced zoospores and were presumed to be var. sporangiiferum. They differed at one locus from genotypes U1–U5. Genotypes U7, U8, U9, and U10 differed from U1–U5 at one, two, three, and five loci, respectively. Sexual isolates occurred in genotypes U1–U3 and U6–U10, and asexual isolates in genotypes U2–U6. Only minor differences were detected in morphology in six isolates (genotypes U8–U10). A single isolate (genotype U10) differed in growth rate from all others. Isozyme analysis is an effective means of distinguishing P. ultimum from nine other species included for comparative purposes and for identifying asexual isolates that cannot be positively identified by morphology. Keywords: Pythium ultimum var. ultimum, Pythium ultimum var. sporangiiferum, isozymes.

Putative Hybrids

Two banding patterns were revealed by phosphoglucomutase (PGM) isozyme analysis of 24 accessions of Cherokee rose (Rosa laevigata Michx.) from eight southeastern states, based on the presence (in 5 accessions) or absence (in 19 accessions) of an additional slow-migrating band. RAPD analysis of these accessions showed a corresponding division into the same two groups determined by PGM analysis, except for two accessions with unique RAPD phenotypes. Field-grown accessions showed distinguishing morphological characters corresponding to the groupings from the isozyme and RAPD analyses. Those in the predominant isozyme and RAPD groups, as well as the two with unique RAPD phenotypes, exhibited smooth lateral stems, while those in both nonpredominant groups exhibited markedly bristly laterals. These results suggest that the 24 accessions are ramets of two major clones with one clone predominating and that, contrary to long-standing belief, the Cherokee rose has not naturalized by reseeding in the southeast. PGM and RAPD analyses of putative Cherokee rose hybrids `Anemone' and `Silver Moon' showed that `Anemone' is likely to be such a hybrid but that `Silver Moon' is not. Historical records revealed that widespread vegetative propagation of the Cherokee rose was initiated in 1820-21 and that L. Wiesener, not J.C. Schmidt, was the originator of `Anemone'.

The Relationship

The utility of isozyme analysis in elucidating the relationship between Australian tree taxa is reviewed. Although little exploited to date, isozyme analysis is shown to be a rapid and relatively powerful method of examining relationships, if used at an appropriate taxonomic level. For Eucalyptus and Acacia, isozymes appear to be the most informative at the lower taxonomic levels. In Eucalyptus delegatensis and Casuarina cunninghamiana, isozyme data strongly support subspecies erected on the basis of morphological characteristics. In Acacia holoserocea, isozyme data predicted the existence of two subspecies, which prediction as later supported by morphological characters. An isozyme study of the phylogenetic relationships within the 'green ash' group of eucalypts yielded a phylogenetic hypothesi comparable to one derived from morphological characters, but also highlighted areas of discrepancy requiring further research. At the generic level, isozyme data for the Australian species of Litsea and Neolitsea successfully separated the two genera and allowed phylogenetic relationships within genera to be hypothesised. For the larger tree genera such as the Eucalyptus and Acacia, however, the utility of isozymes at the higher taxonomic levels is likely to be low, because of the difficulty in establishing homologies between taxa, or insufficient phylogenetic information when taxa being compared have few alleles in common.

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.
