[Ti] Título:Chemotaxonomic Screening of Seed Oils from the Family Saxifragaceae and Comparison with Data on Seed Oils from Grossulariaceae Obtained from Literature.

[Ab] Resumo:Seeds of 25 members of the family Saxifragaceae, 1 × Astilbe, 1 × Darmera, 1 × Leptarrhena, 1 × Tellima, 3 × Mitella, and 18 × Saxifraga were investigated regarding oil content, as well as composition and content of fatty acids and vitamin E active compounds. The results were compared with results obtained from literature for members of the genus Ribes belonging to the closely related family Grossulariaceae to find chemometric differences between the different genera and between members of the family Saxifragaceae and Grossulariaceae, respectively. Members of the family Saxifragaceae are dominated by high amounts of linoleic and α-linolenic acid which together account for about 80% of the total fatty acids. While α-linolenic acid is characteristic for members of the genus Saxifraga, in other genera, linoleic acid is predominant. In comparison to members of the family Saxifragaceae members of the family Grossulariaceae also contain γ-linolenic acid and stearidonic acid which allow a significant differentiation between both families. By principle component analysis, members of both families were divided into three distinct groups, i) species with a high content of α-linolenic acid (genus Saxifraga), ii) species with high amounts of γ-linolenic acid and stearidonic acid (genus Ribes), and iii) species with higher amounts of linoleic acid (other members of the family Saxifragaceae). The composition of the vitamin E active compounds was characterized by a high content of γ-tocopherol in most members of the family Saxifragaceae, but no chemotaxonomic relevance.

[Ti] Título:Conservation genetics of two island endemic Ribes spp. (Grossulariaceae) of Sardinia: survival or extinction?

[Ab] Resumo:Measuring levels of population genetic diversity is an important step for assessing the conservation status of rare or endangered plant species and implementing appropriate conservation strategies. Populations of Ribes multiflorum subsp. sandalioticum and R. sardoum, two endangered endemic species from Sardinia, representing the whole genus on the island, were investigated using ISSR and SSR markers to determine levels and structure of genetic variability in their natural populations. Results indicated medium to low genetic diversity at the population level: Nei's gene diversity for ISSR markers ranged from 0.0840 to 0.1316; the expected heterozygosity (HE ) for SSR ranged from 0.4281 to 0.7012. In addition, only one remnant population of R. sardoum showed a high level of inbreeding, in accordance with its very small size. Regarding the structure of the six R. sandalioticum populations, both principal coordinates analysis (PCoA) and STRUCTURE analysis of ISSR and SSR data highlighted low population structure, although two populations appeared to be clearly distinct from the others. The genetic pattern of the two taxa associated with their different ecological positions indicated resilience of R. sandalioticum populations in fresh and humid habitats and uncertain future resistance for the residual R. sardoum population in xeric calcareous stands. Hence, this study highlights the importance of an integrated conservation approach (genetic plus in situ and ex situ conservation studies/measures) for activating management programmes in these endemic and threatened taxa that can be considered as crop wild relatives of cultivated Ribes species.

[Ab] Resumo:Berry species are economically-important crops worldwide and represent an invaluable source of vitamins and other health-related compounds. Species belonging to the families Rosaceae, Ericaceae and Grossulariaceae provide the most popular fruits, showing a strong diversity in natural and breeding populations as to berry traits (fruit type, size, color, flavor, antioxidant capacity), resistance to a/biotic stress, adaptation to different environment/culture conditions. The small genome size of most diploid berry genera is a remarkable feature for last-generation genomics technologies, molecular genetics and functional studies. This review will cover the literature dealing with molecular research in berry crops, focusing on antioxidant- and flavor-related compounds.

[Ti] Título:Respiration characteristics in temperate rainforest tree species differ along a long-term soil-development chronosequence.

[Ab] Resumo:We measured the response of dark respiration (R(d)) to temperature and foliage characteristics in the upper canopies of tree species in temperate rainforest communities in New Zealand along a soil chronosequence (six sites from 6 years to 120,000 years). The chronosequence provided a vegetation gradient characterised by significant changes in soil nutrition. This enabled us to examine the extent to which changes in dark respiration can be applied across forest biomes and the utility of scaling rules in whole-canopy carbon modelling. The response of respiration to temperature in the dominant tree species differed significantly between sites along the sequence. This involved changes in both R(d) at a reference temperature (R(10)) and the extent to which R(d) increased with temperature (described by E(o), a parameter related to the energy of activation, or the change in R(d) over a 10 degrees C range, Q(10)). Site averaged E(o) ranged from 44.4 kJ mol(-1) K(-1) at the 60-year-old site to 26.0 kJ mol(-1) K(-1) at the oldest, most nutrient poor, site. Relationships between respiratory and foliage characteristics indicated that both the temperature response of respiration (E(o) or Q(10)) and the instantaneous rate of respiration increased with both foliar nitrogen and phosphorus content. The ratio of photosynthetic capacity (Whitehead et al. in Oecologia 2005) to respiration (A(max)/R(d)) attained values in excess of 15 for species in the 6- to 120-year-old sites, but thereafter decreased significantly to around five at the 120,000-year-old site. This indicates that shoot carbon acquisition is regulated by nutrient limitations in the retrogressing ecosystems on the oldest sites. Our findings indicate that respiration and its temperature response will vary according to soil age and, therefore, to soil nutrient availability and the stage of forest development. Thus, variability in respiratory characteristics for canopies should be considered when using models to integrate respiration at large spatial scales.

[Ti] Título:Distribution and contents of phenolic compounds in eighteen Scandinavian berry species.

[Ab] Resumo:Berries contain a wide range of phenolic compounds in different conjugated forms, a fact that makes their simultaneous analysis a difficult task. In this work, soluble and insoluble phenolic compounds were identified and quantified in 18 species of berries by reversed phase high-performance liquid chromatography combined with diode array detection. The analytical results and literature data were used for the identification of the predominant conjugated hydroxycinnamic acids, flavonol glycosides, and anthocyanins in berries from six families, viz. Grossulariaceae, Ericaceae, Rosaceae, Empetraceae, Elaeagnaceae, and Caprifoliaceae. The study showed distinctive similarities among berry species of the same family in the distribution of conjugated forms of phenolic compounds but differences in chromatographic profiles of conjugates and compositions of aglycones especially in the case of anthocyanins. The chromatographic profiles of chokeberry and the related sweet rowanberry (Rosaceae) were exceptionally similar. These data are informative to studies on the authenticity of berry raw materials as well as to those on the evaluation of berries as sources of phenolic compounds.

[Ab] Resumo:The New Zealand tree Quintinia acutifolia has yielded four biflavonoids, the new 2,3,2'',3''-tetrahydroochnaflavone (3), and its 7,7''-di-O-methyl derivative (1). The rare 7-O-methyl-2,3,2'',3''-tetrahydroochnaflavone (2) and 2'',3''-dihydroochnaflavone (4), both previously identified only from members of the Ochnaceae, were also isolated. Structures were determined by spectroscopic methods. This is the first report of biflavonoids from the Grossulariaceae.
