1. Substrates for seedlings with sewage sludge and biochar
ABSTRACT The objective of this study was to evaluate substrates formulated with proportions of sewage sludge (SS)-solarized and SS-biochar in the production of seedlings of two indicator crops: lettuce (Lactuca sativa L.) and black wattle (Acacia decurrens Wild). The study was composed of two experiments conducted in greenhouse, in randomized block designs.

2. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

3. The Ecology and Conservation of Wild Rice, Zizania palustris L., in North America
Resumo O Arroz selvagem é uma espécie de planta enigmática da parte do centro-norte dos EUA. O arroz selvagem (Zizania palustris L.) é encontrado em muitos locais nessa região. Contudo, é uma espécie selvagem, mas ao mesmo tempo produzida de forma semi-domesticada. É uma planta enigmática porque é produzido e colhido em grandes alagados por fazend

4. Visualized protein polymorphisms in leaf sheaths and roots of rice assessed by 2-DE analysis
Abstract To identify potential protein markers associated with tillering in rice, a d10 allelic mutant (JHCA) with a high-tillering dwarf phenotype and a wild-type cultivar (GLA4) with normal numbers of tillers were used to produce a hybrid (F1), and 2-DE (two-dimensional electrophoresis) analysis was conducted in seedling leaf sheaths and roots of the rice

5. Overexpression of salt-induced protein (salT) delays leaf senescence in rice
Abstract Senescence, a highly programmed process, largely determines yield and quality of crops. However, knowledge about the onset and progression of leaf senescence in crop plants is still limited. Here, we report that salt-induced protein (salT), a new gene, may be involved in leaf senescence. Overexpressing salT could prolong the duration of leaves with

6. A Young Seedling Stripe2 phenotype in rice is caused by mutation of a chloroplast-localized nucleoside diphosphate kinase 2 required for chloroplast biogenesis
Abstract Chloroplast development and chlorophyll (Chl) biosynthesis in plants are regulated by many genes, but the underlying molecular mechanisms remain largely elusive. We isolated a rice mutant named yss2 (young seedling stripe2) with a striated seedling phenotype beginning from leaf 2 of delayed plant growth. The mutant developed normal green leaves from

7. Dark septate endophyte decreases stress on rice plants
Abstract Abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. Dark septate endophytes can be symbionts of plants. In the present study, we evaluated the ability of dark septate endophytes isolates to reduce the effects o

8. A walk on the wild side: Oryza species as source for rice abiotic stress tolerance
Abstract Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call f

9. Caracterização de espécies paramagnéticas em sementes por ressonância paramagnética eletrônica
Paramagnetic species were characterized in the seeds of radish wild, rice, mustard, wheat, oats, sorghum, sunflower, soybean, cotton, beans, maize and barley by EPR (Electron Paramagnetic Resonance). Some paramagnetic species present in the soil were also investigated, such as goethite, hematite, magnetite, and ferrihydrite. EPR experiments were performed at

10. Biological control of golden apple snail, Pomacea canaliculata by Chinese soft-shelled turtle, Pelodiscus sinensis in the wild rice, Zizania latifolia field
The wild rice, Zizania latifolia Turcz, used to be one of the important aquatic vegetables cultivated in China. Recently, the golden apple snail - GAS (Pomacea canaliculata (Lamarck)) was found to be a major invasive pest attacking Z. latifolia. To control efficiently GAS, predation by the Chinese soft-shelled turtles (Pelodiscus sinensis) on GAS was evaluat

11. Aspectos fisiológicos e da produção do arroz em resposta ao silício / Physiological and productive aspects of rice plants according to silicon supplying
The objective of this study was to analyze the role of supplemental silicon (Si) in the biomass accumulation and grain yield of rice (Oryza sativa L.). Different experiments were carried out in which wild rice plants (japonica subsp. Oochikara - WT) and mutant defective for the absorption of Si - lsi1 (Low silicon rice 1) were raised under hydroponics condit

12. Genetic diversity of American wild rice species
Studies on genetic diversity and genetic structure of natural populations are important in order to define strategies for in situ and ex situ conservation actions and for plant pre-breeding programs. Aiming to assess the genetic diversity and genetic structure of three wild American Oryza species with isozyme markers, 14 populations of the diploid O. glumaep
