New species of leaf-mining Phyllonorycter (LepidopteraGracillariidae) from Siberia feeding on Caragana (Fabaceae).

ABSTRACT: During a DNA barcoding campaign of leaf-mining Gracillariidae from the Asian part of Russia, a new species of Phyllonorycter Hübner, feeding on the Siberian pea shrub, Caraganaarborescens Lam. (Fabaceae) was discovered in Siberia. Here, this taxon is described as Phyllonorycterivani sp. n. Among Fabaceae-feeding Phyllonorycter, so far only P.caraganella (Ermolaev) has been known to develop on Caragana. Phyllonorycterivani and P.caraganella show a large divergence in morphology (external and male genitalia) and barcode region of the mtDNA-COI gene (8.6%). They feed on different host plants species and have different ranges in Russia. We show that DNA barcode data weakly supports the Fabaceae-feeding species groups. In addition, we show that morphologically (strongly) and genetically (weakly), P.ivani has affinity to the haasi species group, a West Palearctic group with asymmetrical male genitalia.

Water permeability/impermeability in seeds of 15 species of Caragana (Fabaceae).

Project description:Majority legumes in the temperate and arctic zones have water-impermeable seeds (physical dormancy, PY). However, various authors have reported that seeds of some Caragana species are water-permeable and thus non-dormant. We (1) tested seeds of 15 species of Caragana matured in the same site in 2014, 2016 and/or 2017 for presence of PY, (2) determined if dry storage decreased or increased the percentage of seeds with PY and (3) located the site on the seed coat of 11 species where water enters the seed. Sixty-three percent and 45% of the seeds of C. roborovskyi had PY in 2016 and 2017, respectively, but only 0-14% of the seeds of the other 14 species had PY. The palisade layer in the seed coat of water impermeable seeds had no cracks in it, whereas cracks were present in the palisade layer of water-permeable seeds. Year of collection and dry storage had significant effects on imbibition of two species (C. acanthophylla and C. roborovskyi). In two (C. acanthophylla and C. roborovskyi) of the 11 species tested, the hilum was the site of water entry into seeds (control seeds, not any dormant broken treatments), but for the other nine species tested water entered through all parts of the seed coat.

Systematics of Phyllocnistis leaf-mining moths (Lepidoptera, Gracillariidae) feeding on dogwood (Cornus spp.) in Northeast Asia, with the description of three new species.

Project description:During an ongoing DNA-barcoding campaign of the leaf-mining moths that feed on woody plants in Northeast Asia, four lineages of the genus Phyllocnistis (Gracillariidae, Phyllocnistinae) were discovered on dogwood (Cornus spp): P. cornella Ermolaev, 1987 on C. controversa Hemsl. (Japan: Hokkaido) and three new species - one feeding on C. controversa, C. florida L. and C. macrophylla Wall. in Japan (Honshu, Shikoku, Kyushu), a second species on C. macrophylla in China (Yunnan) and a third on Siberian dogwood Cornus alba L. in Russia (Siberia). All these species showed differences in morphology, in the barcode region of the cytochrome c oxidase I gene and in two nuclear genes (histone H3 and 28S ribosomal RNA). No correlation was found between the deep mitochondrial splits observed and the Wolbachia infection pattern. Based on both morphological and molecular evidence, the three recently discovered lineages are described here as new species: P. indistincta Kobayashi & Triberti, sp. n. (Japan), P. saepta Kirichenko, Ohshima & Huang, sp. n. (China) and P. verae Kirichenko, Triberti & Lopez-Vaamonde, sp. n. (Russia). In addition, the authors re-describe the adult morphology of P. cornella, provide the first record of this species from Japan and highlight the diagnostic characters that allow these Cornus-feeding Phyllocnistis species to be distinguished.

Trolliusaustrosibiricus (Ranunculaceae), a new species from South Siberia.

Project description:Trolliusaustrosibiricus Erst & Luferov, sp. nov., a new species from Russian South Siberia is described and illustrated. This new species is endemic to Western and Central Siberia. Morphologically, it is close to the East Asian species T.chinensis and T.macropetalus. However, it differs from the aforementioned species due to the morphology of the rhizomes, aerial shoots, sepals and petals. This species is also distinguished from T.asiaticus, which is widespread in Russia (Western and Eastern Siberia), Mongolia, China, north-eastern Kazakhstan and in the northeast of the European part of Russia, in having a smaller number of sepals, longer persistent styles and petals longer than sepals. In addition, an identification key for all Russian species is given and all species have been discussed.

Combined high leaf hydraulic safety and efficiency provides drought tolerance in Caragana species adapted to low mean annual precipitation.

Project description:Clarifying the coordination of leaf hydraulic traits with gas exchange across closely-related species adapted to varying rainfall can provide insights into plant habitat distribution and drought adaptation. The leaf hydraulic conductance (Kleaf ), stomatal conductance (gs ), net assimilation (A), vein embolism and abscisic acid (ABA) concentration during dehydration were quantified, as well as pressure-volume curve traits and vein anatomy in 10 Caragana species adapted to a range of mean annual precipitation (MAP) conditions and growing in a common garden. We found a positive correlation between Ψleaf at 50% loss of Kleaf (Kleaf P50 ) and maximum Kleaf (Kleaf-max ) across species. Species from low-MAP environments exhibited more negative Kleaf P50 and turgor loss point, and higher Kleaf-max and leaf-specific capacity at full turgor, along with higher vein density and midrib xylem per leaf area, and a higher ratio of Kleaf-max : maximum gs . Tighter stomatal control mediated by higher ABA accumulation during dehydration in these species resulted in an increase in hydraulic safety and intrinsic water use efficiency (WUEi ) during drought. Our results suggest that high hydraulic safety and efficiency combined with greater stomatal sensitivity triggered by ABA production and leading to greater WUEi provides drought tolerance in Caragana species adapted to low-MAP environments.
