Succulents are an important component of the mixed bushveld. Although the nurse plant syndrome is known from arid areas, association of succulents with woody canopy has ot been studied in non-arid areas. The study was done in two phases, the first being to confirm the existence of an association and the second being to investigate a possible cause of the association. The three species studied were all significantly associated with woody canopy. All of the relatively small (0-1 m) Euphorbia ingens plants and most of the relatively small (0-0.5m) Aloe marlothii and Opuntia vulgaris plants encountered were beneath woody canopy. There was a very strong significant association between being damaged by fire and growing between woody canopies for all three species. Fires are likely to be lethal to any plants of the study species that are shorter than about 1 m. In any area where fires are frequent there are likely to be fewer young plants of the study species between woody canopies than there will be within the protection of a bush clump.

Efficient protocols of callus culture indirect organogenesis were established for mature internodal segments of Boucerosia procumbens (Asclepiadoideae). When MS medium was supplemented with different concentration of auxins, the texture of the callus varied according to the nature of auxin. Optimum callus was developed on MS medium supplemented with 3mg/l IAA. Best response (65%) of callus proliferation was obtained when MS medium fortified with 2iP 2mg/l + Zeatin 0.5 mg/l. IAA was most effective in producing the highest frequency of organogenic culture. Regeneration of callus into plantlets could not be achieved inthe present study. The regenerated shoots were rooted on half strength MS medium fortified with 0.1 mg/l NAA. 57% of the rooted shootlets survived in the field.

Functional And Phylogenetic Diversity

The multifunctionality and delivery of ecosystem services from green roofs is improved by biological diversity of the roof vegetation. However, the frequency and intensity of drought episodes on extensive green roofs may limit the use of non-succulent species and the potential functional and phylogenetic diversity of the vegetation. Wind accelerates water use by plants and desiccation of the green roof substrate, and may be a key factor in selection of non-succulent plant species for green roofs. In this study, we tested wind interactions with green roof substrate composition and the effects on plant and substrate water balance, overall plant performance, and wilting and survival of three non-succulent species (Plantago maritima L., Hieracium pilosella L., and Festuca rubra L.) under realistic prolonged water deficit conditions. We found that, regardless of species or substrate tested, wind accelerated drought response. Drought-stressed plants exposed to wind wilted and died earlier, mostly due to more rapid desiccation of the growth substrate (critical substrate moisture content was 6-8%). The moderate wind levels applied did not affect plant performance when not combined with drought. Species with contrasting growth forms showed similar responses to treatments, but there were some species-specific responses. This highlights the importance of including wind to increase realism when evaluating drought exposure in non-succulent green roof vegetation.

Hylocereus Undatus

Pitaya (Hylocereus undatus and H. polyrhizus Britt. & Rose), a perennial succulent plant grown in the tropics, is becoming an emerging and important fruit plant in Taiwan. In September of 2009 and 2010, a number of pitaya plants were found to have a distinctive canker on stems. The disease expanded quickly to most commercial planting areas in Taiwan (e.g., Pintung, Chiayi, and Chunghua). Symptoms on the stem were small, circular, sunken, orange spots that developed into cankers. Pycnidia were erumpent from the surface of the cankers and the stems subsequently rotted. After surface disinfestation with 0.1% sodium hypochloride, tissues adjacent to cankers were placed on acidified potato dextrose agar (PDA) and incubated at room temperature for 1 week, after which colonies with dark gray-to-black aerial mycelium grew. Hyphae were branched, septate, and brown and disarticulated into 0- to 1-septate arthrospores. Sporulation was induced by culturing on sterile horsetail tree (Casuarina equisetifolia) leaves. Conidia (12.79 ± 0.72 × 5.14 ± 0.30 μm) from pycnidia were one-celled, hyaline, and ovate. The internal transcribed spacer (ITS) region of ribosomal DNA was PCR amplified with primers ITS1 and ITS4 (2) and sequenced. The sequence (GenBank Accession No. HQ439174) showed 99% identity to Neoscytalidium dimidiatum (Penz.) Crous & Slippers (GenBank Accession No. GQ330903). On the basis of morphology and nucleotide-sequence identity, the isolates were identified as N. dimidiatum (1). Pathogenicity tests were conducted in two replicates by inoculating six surface-sterilized detached stems of pitaya with either mycelium or conidia. Mycelial plugs from 2-day-old cultures (incubated at 25°C under near UV) were inoculated to the detached stems after wounding with a sterile needle. Conidial suspensions (103 conidia/ml in 200 μl) were inoculated to nonwounded stems. Noninoculated controls were treated with sterile medium or water. Stems were then incubated in a plastic box at 100% relative humidity and darkness at 30°C for 2 days. The symptoms described above were observed on inoculated stems at 6 to 14 days postinoculation, whereas control stems did not develop any symptoms. N. dimidiatum was reisolated from symptomatic tissues. To our knowledge, this is the first report of N. dimidiatum causing stem canker of pitaya. References: (1) P. W. Crous et al. Stud.

Abstract Hoodia gordonii, family Asclepiadaceae, is a succulent plant and is traditionally used in southern Africa for its appetite-suppressant properties. A high-performance liquid chromatographic (HPLC) method with UV detection for analysis of 11 oxypregnane glycosides from H. gordonii has been developed. The simultaneous analysis of 11 oxypregnane glycosides was achieved with a Phenomenex (Torrance, CA) reversed-phase C18 column using gradient mobile phase of water and acetonitrile, both containing 0.025 trifluoroacetic acid. The developed method was applied to the identification of oxypregnane glycosides in 3 different species of Hoodia and 23 related genera. The HPLC profiles of various plant samples were compared for the presence of oxypregnane glycosides.

Data Deficient

Aizoaceae is the largest succulent plant family in the world, including in excess of 1800 species. Despite its richness, a large proportion of its taxa are listed as data deficient and as such, has been identified as the top priority for taxonomic research in South Africa. Limitations to accurate taxonomic identification of taxa in the family may be partly attributed to the degree of technical knowledge required to identify taxa in the Aizoaceae. DNA barcoding may provide an alternative method of identification; however, the suitability of commonly used gene regions has not been tested in the family. Here, we analyse variable and parsimony informative characters (PIC), as well as the barcoding gap, in commonly used plastid regions (atpB-rbcL, matK, psbA-trnH, psbJ-petA, rpl16, rps16, trnD-trnT, trnL-trnF, trnQ-rps16, and trnS-trnG) and the nuclear region ITS (for Aizooideae only) across two subfamilies and two expanded clades within the Aizoaceae. The relative percentage of PIC was much greater in subfamilies Aizooideae and Mesembryanthemoideae than in Ruschioideae. Although nrITS had the highest percentage of PIC, barcoding gap analyses identified neither ITS nor any chloroplast region as suitable for barcoding of the family. From the results, it is evident that novel barcoding regions need to be explored within the Aizoaceae.
