1. A germline-targeted genetic screen for xrn-2 suppressors identifies a novel gene C34C12.2 in Caenorhabditis elegans
Abstract XRN2 is an evolutionarily conserved 5’-to-3’ exoribonuclease, which degrades or trims various types of RNA in the nucleus. Although XRN-2 is essential for embryogenesis, larval development and reproduction in Caenorhabditis elegans, relevant molecular pathways remain unidentified. Here we create a germline-specific xrn-2 conditional mutant and p

2. Reaction of popcorn lines (s7) cultivated in distinct phosphorus levels to Bipolaris maydis infection
RESUMO O milho-pipoca apresenta alta suscetibilidade a helmintosporiose (Bipolaris maydis) (h-Bm). O melhoramento genético desta cultura deve priorizar a resistência a h-Bm e desenvolver cultivares que ofereçam maior sustentabilidade ao cultivo, principalmente em solos com escassez de fósforo (P). O P-mineral normalmente é suprido à cultura do milho pe

3. Plant growth-promoting bacteria as inoculants in agricultural soils
Abstract Plant-microbe interactions in the rhizosphere are the determinants of plant health, productivity and soil fertility. Plant growth-promoting bacteria (PGPB) are bacteria that can enhance plant growth and protect plants from disease and abiotic stresses through a wide variety of mechanisms; those that establish close associations with plants, such as

4. DINÂMICA DO FÓSFORO NA INTEGRAÇÃO LAVOURA-PECUÁRIA SOB SISTEMA PLANTIO DIRETO / Phosphurus dynamic in crop livestock integration under notillage.
The necessity to preserve the soil, coupled with the constant search for lower production costs and increased productivity resulted in the use no-tillage (NT). Efficient technique in the preservation and use of highly weathered soils (tropical and subtropical soils). However, only the continuous cultivation of monocultures has been implicated in reduced prof

5. Acumulação de nutrientes e metais pesados em solo, água e hortaliças em áreas cultivadas com olerícolas no Agreste de Pernambuco. / Accumulation of nutrients and heavy metals in soil, water and fruits in areas cultivated with vegetables in the Agretes region of Pernambuco state.
Increasing world population elevates the demand for food. Then, it s a constant challenge to ensure food with quantity and quality appropriate. The management of soil fertility using fertilizers and controlling pests and weeds are necessary strategies for maintaining or increasing agricultural production. Agrochemicals are anthropogenic sources potentially p

7. Manejo da calagem e da adubação fosfatada para a cultura da mandioca em solo de cerrado.
ABSTRACT: Soil acidity and soil phosphorus deficiency may be constraints factors to cassava production in cerrado soils. Therefore, the cultivation of cassava requires the adequate management of soil acidity and fertility, by the using of the appropriate combination of lime and phosphate fertilizer. Field experiments were carried out combining lime and phosp

9. Aspectos relacionados ao manejo da adubação fosfatada em solos do Cerrado.
ABSTRACT: The management of phosphate fertilization in the Cerrado soils has been studied for almost 40 years and represents an extremely important technology towards to a successfull agricultural exploration of the region. However, many aspects related to soil phosphorus dynamic, availability, and its use efficiency by crops remain not well understood, and

10. Utilização do húmus de minhoca como adubo orgânico para a mandioca em solo de Cerrado.
ABSTRACT: The production system with cassava has been increased in the Cerrado Bioma, where the soils are naturally acid with low nutrients content. Cassava is usually cultivated with low or no inputs of lime and fertilizers. Nevertheless, it has been found responses of cassava to those inputs, mainly to phosphate fertilization, since the continuous cropping

ABSTRACT: The sweet passion fruits is a native species of Brazil. It is very well adapted to tropical regions, and can be found growing in wild conditions or cultivated by small farmers in many regions. It is consumed mainly as a fresh fruit, splitting with a knife in two parts and using a spoon to collect the pulp with the seeds. The concentrated juice, eas

12. Desenvolvimento inicial e nutrição da cagaita em áreas de Cerrado degradado.
RESUMO: Apesar das limitações em fertilidade dos solos ácidos do Cerrado, as plantas nativas do bioma possuem diferentes mecanismos de adaptação. O objetivo deste trabalho foi determinar o efeito de doses de nitrogênio (N) e fósforo (P) em mudas de cagaita (Eugenia dysenterica Mart. ex DC.) plantadas em áreas ocupadas com pastagem de Brachiaria decum
