1. Management priorities for exotic plants in an urban Atlantic Forest reserve
ABSTRACT Biological diversity is directly affected by alien species, even though the diagnosed impacts vary with scale. Early identification of the invasion of natural patches is essential for effective conservation actions. We aimed to determine the exotic plant species present inside Fontes do Ipiranga State Park (PEFI), an urban protected area located in

2. InBUy database of Invasive and Alien Species (IAS) in Uruguay: a useful tool to confront this threat to biodiversity
In Uruguay, as well as in other regions of the world, IAS cause negative impacts on natural and managed ecosystems. The use of databases is a helpful tool to elaborate different strategies for prevention and control, and to develop policies and scientific analyses related to IAS. The database of IAS in Uruguay (InBUy) was developed during two time periods (2

3. Contaminação biológica e o uso de animais de montaria no Parque Nacional da Serra do Cipó - MG / Biological contamination and horse hiding in the Serra do Cipó National Park MG
Serra do Cipó National Park has undergone a major management challenge that is the definition of the use of horse riding by the visitors. Recently, the Brazilian Government launched a document entitled Diretrizes para visitação em unidades de conservação (Guidelines for visitation in protected areas) which dictates certain rules for recreation ecology a

4. PRESENÇA DE GRAMÍNEAS FORRAGEIRAS EXÓTICAS EM ÁREA DE FLORESTA OMBRÓFILA DENSA EM BLUMENAU/ SC: PLANTAS FORRAGEIRAS SOB O ENFOQUE DE PLANTAS INVASORAS
Four forage grasses from botanic alien species - Tripsacum dactyloides, Axonopus scoparius, Panicum maximum and Melinis minutiflora - were found in a fragment of Forest Dense Ombrófila Submontana in process of recruitment, in an urban environment in Blumenau, Santa Catarina state, in the South of Brazil. The vegetation of this forest area was inventoried. T

5. Invading potencial from Singapure almond (Terminalia catappa L.) in resting forest / Potencial invasor do chapéu-de-sol (Terminalia catappa L.) em área de restinga
Current and the next decade they will be identified in the time as group of the most excellent concerns with the ambient quality of the planet. Subjects as global heating and the eminent loss of the amount and quality of the water are argued constantly. A more specific ambient problem has worried specialists in the world all, including Brazil. One is about t

6. Morfometria geometrica e modelagem matematica em Lantana camara L. (Verbenaceae) / Mathematical modeling and mporphometric relations in the vegetative body of Lantana camara L. (Verbenaceae) in Brazil
The taxonomy of Lantana camara has been the target of discussion by taxonomists all over the world. The morphological, ecological and chemical plasticity observed is very extensive. Some autors consider that L. camara is a species complex instead of a monotypic taxon, composed of up to 150 different taxa. In this sudy, the variability of L. camara is studied

7. The N-Terminal Region of Arabidopsis Cystathionine γ-Synthase Plays an Important Regulatory Role in Methionine Metabolism1
Cystathionine γ-synthase (CGS) is a key enzyme of Met biosynthesis in bacteria and plants. Aligning the amino acid sequences revealed that the plant enzyme has an extended N-terminal region that is not found in the bacterial enzyme. However, this region is not essential for the catalytic activity of this enzyme, as deduced from the complementation test of a

8. Physiologically mediated self/non-self discrimination in roots
Recent evidence suggests that self/non-self discrimination exists among roots; its mechanisms, however, are still unclear. We compared the growth of Buchloe dactyloides cuttings that were grown in the presence of neighbors that belonged to the same physiological individual, were separated from each other for variable periods, or originated from adjacent or r

9. Species-specificity of rRNA gene transcription in plants manifested as a switch in RNA polymerase specificity.
Rapid evolution of ribosomal RNA (rRNA) gene promoters often prevents their recognition in a foreign species. Unlike animal systems, we show that foreign plant rRNA gene promoters are recognized in an alien species, but tend to program transcription by a different polymerase. In plants, RNA polymerase I transcripts initiate at a TATATA element (+1 is underli

10. Selection and Identification of a Spontaneous Alien Chromosome Translocation in Wheat
A wheat (Triticum aestivum L. emend Thell) disomic addition line (2n = 6x = 44), SH1–152–2, with a pair of Elytrigia pontica (Podp.) Holub 2n = 10x = 70 [syn. Agropyron elongatum (Host) P.B.] chromosomes controlling blue aleurone color was crossed with a short-statured spring wheat `Sonora 64' (T. aestivum). Isoline pairs of blue-disomic addition lines a

11. Oviposition of the invasive two-spotted leafhopper on an endemic tree: Effects of an alien weed, foliar pubescence, and habitat humidity
The two-spotted leafhopper, Sophonia rufofascia (Kuoh and Kuoh), is an exotic pest from South-East Asia that attacks a wide variety of plant species in Hawaii. Myrica faya Aiton is an aggressive exotic weed that displaces and excludes native plants in Hawaiian forests. It has been argued that because of the high nutritional quality of its foliage, M. faya mi

12. Analysis of Genes Controlling F1 Sterility in Rice by the Use of Isogenic Lines
In order to look into the genetic basis of intervarietal F1 sterility in rice (Oryza sativa L.), a series of backcrosses (up to B13) was carried out using Taichung 65 (Japonica type) as the recurrent parent and several Indica varieties as donor parents. A number of "isogenic F1-sterile lines" were isolated by test-crossing fertile F2 plants obtained from the
