Kaisupeea: a new genus of Gesneriaceae centred in Thailand

The genus Kaisupeea is established for Boea herbacea , a species long recognised as being out of place in Boea , and two new species closely allied to it. These plants produce annual flowering stems whose basal leaves may be represented by broad foliaceous cataphylls. Kaisupeea herbacea and K. cyanea have spirally twisted fruit-valves, but those of K. orthocarpa are straight. Kaisupeea ranges from Moulmein in Burma [Mawlamyne in Myanmnar] eastwards across Thailand to Bassac on the Mekong river in lower Laos and south to the neighbourhood of Satun on the south coast of Thailand just north of the Malaysian border.

Hand.-Mazz., from which it differs by having pendent stem, basal leaves and lower stem leaves purple beneath, stem leaves linear, hispid above, and broader phyllaries. The new variety is also possibly similar to A. ageratoides var. micranthus Ling in the linear leaves and white ligules, but differs by having the phyllaries green at apex, 1.25–1.75 mm wide, and the obvious creeping underground rhizomes.     

DNA-based method for rapid identification of the pine pathogen, Phytophthora pinifolia

Phytophthora pinifolia causes a needle and shoot disease in Pinus radiata , referred to as 'Daño Foliar del Pino'. This newly discovered disease requires intensive research efforts that necessitate the processing of large numbers of samples for which accurate identification, often by people not experienced in Phytophthora taxonomy, is required. The aim of this study was, therefore, to develop species-specific primers for P. pinifolia that amplify the internal transcribed spacer region of the ribosomal operon and the nuclear Ypt 1 gene, respectively. The primers were tested over several Phytophthora spp., as well as fungi isolated from P. radiata . In all cases, only P. pinifolia was amplified. In addition to the species-specific primers, a PCR-restriction fragment length polymorphism protocol using available Phytophthora genus-specific primers was also used to generate a species-specific profile for P. pinifolia . This provided a characteristic profile that allows the identification of P. pinifolia , and it could also discriminate between 27 different species of Phytophthora . Both techniques reported in this study make it possible to identify large numbers of P. pinifolia cultures accurately and efficiently, which will be important for both quarantine work and biological research on this important new pathogen.     

Impatiens macrovexilla var. yaoshanensis S. X. Yu,Y. L. Chen & H. N. Qin,a new variety of Balsaminaceae from Guangxi,China

Impatiens macrovexilla Y. L. Chen var. yaoshanensis S. X. Yu, Y. L. Chen & H. N. Qin, a new variety of Balsaminaceae from Guangxi, China, is described. Variety yaoshanensis differs from the typical variety by having ovate-orbicular or ovate-oblong leaves, entire lateral sepals, an obvious auricle and entire distal lobe of the alae and visibly ridged seeds. Micromorphological characters of the pollen grains and seed surface under SEM of the two varieties also support the recognition of this taxon.

Chrysolina herbacea modulates terpenoid biosynthesis of Mentha aquatica L

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant volatiles was tested by Y-tube olfactometer bioassays. Total RNA was extracted from control plants, mechanically damaged leaves, and leaves damaged by herbivores. The terpenoid quantitative gene expressions (qPCR) were then assayed. Upon herbivory, M. aquatica synthesizes and emits (+)-menthofuran, which acts as a deterrent to C. herbacea. Herbivory was found to up-regulate the expression of genes involved in terpenoid biosynthesis. The increased emission of (+)-menthofuran was correlated with the upregulation of (+)-menthofuran synthase.
