1. New initiatives for Brazilian aquatic plant data management
ABSTRACT Initiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management and protection of wetlands and natural resources, as well as reveal knowledge gaps regarding aquatic plants and wetlands. Furthermore, such initiatives can contrib

2. Anacardiaceae R. Br. na flora fanerogâmica do estado de São Paulo / Anacardiaceae R.Br. in the phanerogamic flora of the São Paulo state
O estudo da família Anacardiaceae tem o objetivo de contribuir com o plano mais amplo do levantamento da \"Flora Fanerogâmica do Estado de São Paulo\", que vem sendo subsidiado pela FAPESP desde 1994 e conta com a colaboração de pesquisadores de muitas universidades e institutos de pesquisa do Estado. As Anacardiaceae compreendem cerca de 81 gêneros e

3. The need to carry out re-inventory of plant pathogenic fungi
Plant pathogenic fungi have long been documented through concerted efforts of mycologists and plant pathologists; these records have served as the basis for regional and countrywide checklists which have since been put into databases listing hosts and associated fungi. They are used by governments and scientists to formulate trade quarantine policies and det

4. Revisão taxonomica das especies neotropicais extra-amazonicas de Sloanea L. (Elaeocarpaceae) na America do Sul / Taxonomy review of neotropic species of extra-amazonian Sloanea L. (Elaeocarpaceae)
Elaeocarpaceae inclui 15 gêneros, com aproximadamente 500 espécies distribuídas em regiões tropicais e subtropicais do globo, em com exceção dos continentes africano e europeu. O gênero Sloanea reúne 120 táxons, dos quais cerca de 40 ocorrem no Brasil em diversos tipos de vegetação, principalmente na Floresta Amazônica e na Floresta Atlântica. O

5. Systematics of Helieae Gilg (Gentianaceae) / Sistemática de Helieae Gilg (Gentianaceae)
Helieae, one of the six Gentianaceae tribes, comprises about 23 genera and over 200 species found exclusively in the Neotropics. It is a highly diverse assemblage of plants, which have traditionally been problematic regarding generic circumscriptions. Several Helieae genera were understudied and phylogenetic relationships within the tribe were unclear. On th

6. Sistemática morfológica e molecular de ácaros fitófagos do gênero Brevipalpus Donnadieu de importância econômica e quarentária para o Brasil / Morphological and molecular systematics of phytophagous mites of brevipalpus donnadieu genus of economic and quarantine importance to Brazil
Brevipalpus Donnadieu is the most importante genus in the Tenuipalpidae family. This genus presents about 300 species distributed around the world. Brevipalpus mites present agricultural importance because they are pests of several crops and especially due to their role as vectors of serious plant viroses. In Brazil, the main Brevipalpus species are B. phoen

7. Rates and patterns of chloroplast DNA evolution.
The chloroplast genome (cpDNA) of plants has been a focus of research in plant molecular evolution and systematics. Several features of this genome have facilitated molecular evolutionary analyses. First, the genome is small and constitutes an abundant component of cellular DNA. Second, the chloroplast genome has been extensively characterized at the molecul

8. RNA editing in bryophytes and a molecular phylogeny of land plants.
RNA editing has been observed to date in all groups of vascular plants, but not in bryophytes. Its occurrence was therefore assumed to correlate with the evolution of tracheophytes. To gain more insight into both the phylogeny of early land plants and the evolution of mitochondrial RNA editing we have investigated a number of vascular and non-vascular plant

9. Resistant tissues of modern marchantioid liverworts resemble enigmatic Early Paleozoic microfossils
Absence of a substantial pretracheophyte fossil record for bryophytes (otherwise predicted by molecular systematics) poses a major problem in our understanding of earliest land-plant structure. In contrast, there exist enigmatic Cambrian–Devonian microfossils (aggregations of tubes or sheets of cells or possibly a combination of both) controversially inter
