15. Danos qualitativos e quantitativos de Cinara atlantica (Wilson) (Hemiptera, Aphididae) em mudas de Pinus taeda Linnaeus (Pinaceae)1
O pulgão-gigante-do-pinus, Cinara atlantica (Wilson, 1919) (Hemiptera, Aphididae), é considerado atualmente uma das principais pragas dos reflorestamentos de pinus no Brasil. Como a informação sobre os danos causados por esta praga é restrita, esta pesquisa teve como objetivo caracterizar e quantificar os danos de C. atlantica em Pinus taeda. O experime

16. Occurrence of Cinara spp. (Hemiptera, Aphididae) on Pinus spp. (Pinaceae), in the county of Lages-SC, Brazil
Ocorrência de Cinara spp. (Hemiptera, Aphididae) em Pinus spp. (Pinaceae), em Lages-SC, Brasil O levantamento populacional do pulgão-gigante-do-pinus, Cinara spp. foi desenvolvido em duas áreas de plantio de Pinus elliottii utilizando armadilhas-amarelas-de-água, durante dois anos, de julho de 1997 a junho de 1999. Durante o período de coletas, a espéc

17. Development and consumption capacity of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) fed with Cinara spp. (Hemiptera, Aphididae) under three temperatures
The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera: Aphididae) are pests on Pinus spp. (Pinaceae) in the South and Southeast regions of Brazil. Larvae of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) were observed feeding voraciously on these aphid colonies. In order to evaluate their potentia

18. Ocorrência e flutuação populacional de Chrysopidae (Neuroptera) em áreas de plantio de Pinus taeda (L.) (Pinaceae) no sul do Paraná
The lacewings are very voracious predators of aphids. The objective of this research was to evaluate the occurrence of adult chrysopids in areas of Pinus reforestation where the giant conifer aphid Cinara spp. (Hemiptera: Aphididae) is causing severe damages. A total of 47 specimens were collected during one year and identified as: Chrysoperla externa (Hagen

19. Seed plant phylogeny inferred from all three plant genomes: Monophyly of extant gymnosperms and origin of Gnetales from conifers
Phylogenetic relationships among the five groups of extant seed plants are presently quite unclear. For example, morphological studies consistently identify the Gnetales as the extant sister group to angiosperms (the so-called “anthophyte” hypothesis), whereas a number of molecular studies recover gymnosperm monophyly, and few agree with the morphology-b

20. Phylogeny of seed plants based on all three genomic compartments: Extant gymnosperms are monophyletic and Gnetales' closest relatives are conifers
Efforts to resolve Darwin's “abominable mystery”—the origin of angiosperms—have led to the conclusion that Gnetales and various fossil groups are sister to angiosperms, forming the “anthophytes.” Morphological homologies, however, are difficult to interpret, and molecular data have not provided clear resolution of relationships among major groups

21. Ecological and evolutionary significance of mycorrhizal symbioses in vascular plants (A Review)
Mycorrhizae, the symbioses between fungi and plant roots, are nearly universal in terrestrial plants and can be classified into two major types: endomycorrhizae and ectomycorrhizae. About four-fifths of all land plants form endomycorrhizae, whereas several groups of trees and shrubs, notably Pinaceae, some Cupressaceae, Fagaceae, Betulaceae, Salicaceae, Dipt

22. Biochemistry of Oleoresinosis 1: Monoterpene and Diterpene Biosynthesis in Lodgepole Pine Saplings Infected with Ceratocystis clavigera or Treated with Carbohydrate Elicitors
Elevated levels of monoterpenes and diterpene resin acids are produced in the stems of lodgepole pine (Pinus contorta var latifolia) saplings when wounded and inoculated with the blue-stain fungus Ceratocystis clavigera or when wounded and treated with a pectic fragment from tomato leaves (PIIF) or a fungal cell wall fragment (chitosan). This induced defensi

23. Chloroplast genomes of two conifers lack a large inverted repeat and are extensively rearranged.
Chloroplast genomes of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] and radiata (Monterey) pine [Pinus radiata D. Don], two conifers from the widespread Pinaceae, were mapped and their genomes were compared to other land plants. Douglas-fir and radiata pine lack the large (20-25 kilobases) inverted repeat that characterizes most land plants. To our kno

24. Tissue-Specific and Development-Dependent Accumulation of Phenylpropanoids in Larch Mycorrhizas.
The tissue-specific and development-dependent accumulation of secondary products in roots and mycorrhizas of larch (Larix decidua Mill.; Pinaceae) was studied using high-performance liquid chromatography and histochemical methods. The compounds identified were soluble catechin, epicatechin, quercetin 3-O-[alpha]-rhamnoside, cyanidin- and peonidin 3-O-[beta]-
