O objetivo deste trabalho foi avaliar os componentes da produção de girassol cultivado em sistema de semeadura direta, em resposta aos teores de fósforo (P) no solo. O híbrido de girassol Agrobel 960 foi semeado em fevereiro de 2009, em área de Latossolo Vermelho- Amarelo distrófico (LVAd), em experimento de longa duração conduzido em Ponta Grossa, PR. Durante a condução do experimento, as parcelas foram adubadas com 0; 60; 120; 240 e 480 kg ha-1 de P2O5, criando-se uma curva de resposta ao fósforo. No estádio de maturação fisiológica, avaliou-se a produtividade, o número de aquênios por capítulo, o peso de 1000 aquênios e a altura de planta. Os teores de fósforo no solo variaram significativamente em função das doses do nutriente aplicadas no solo. As respostas ao aumento dos teores de P no solo foram semelhantes para todas as variáveis avaliadas. A obtenção de 90 % da produção máxima de grãos foi conseguida quando o teor de P no solo foi de 8,2 mg dm-3. Esse teor de fósforo no solo pode ser considerado o nível crítico do nutriente em latossolos de origem sedimentar do Paraná, para o girassol cultivado na safrinha. Phosporus on sunflower crop. The aim of this study was to evaluate yield components of sunflower grown under notillage system, in response to phosphorus (P) in soil. Sunflower hybrid Agrobel 960 was sown in February 2009 in a dystrophic Typic Hapludoxin long-term experiment runned in Ponta Grossa, PR, Brazil. During the experiment, the plots were fertilized with 0, 60,120, 240 and 480 kg ha-1 P2O5, creating a response curve to phosphorus. At physiological maturity stage, we evaluated yield, number of achenes per head, 1000-seed weight and plant height. The levels of phosphorus in the soil varied significantly depending on the applied rates of the nutrient in the soil. All evaluated parameters present similar reponses to the increase of soil P levels. 90% of the maximum yield was achieved when the P content in soil was 8.2 mg dm-3. This phosphorus content in soil can be considered the critical level of nutrient in oxysols originating from sedimentary rocks in Parana State, for sunflower grown during off-season.

Economically feasible bioethanol process from lignocellulose requires efficient fermentation by yeast of all sugars present in the hydrolysate. However, when exposed to lignocellulosic hydrolysate, Saccharomyces cerevisiae is challenged with a variety of inhibitors that reduce yeast viability, growth, and fermentation rate, and in addition damage cellular structures. In order to evaluate the capability of S. cerevisiae to adapt and respond to lignocellulosic hydrolysates, the physiological effect of cultivating yeast in the spruce hydrolysate was comprehensively studied by assessment of yeast performance in simultaneous saccharification and fermentation (SSF), measurement of furaldehyde reduction activity, assessment of conversion of phenolic compounds and genome‐wide transcription analysis. The yeast cultivated in spruce hydrolysate developed a rapid adaptive response to lignocellulosic hydrolysate, which significantly improved its fermentation performance in subsequent SSF experiments. The adaptation was shown to involve the induction of NADPHdependent aldehyde reductases and conversion of phenolic compounds during the fed‐batch cultivation. These properties were correlated to the expression of several genes encoding oxidoreductases, notably AAD4, ADH6, OYE2/3, and YML131w. The other most significant transcriptional changes involved genes involved in transport mechanisms, such as YHK8, FLR1, or ATR1. A large set of genes were found to be associated with transcription factors (TFs) involved in stress response (Msn2p, Msn4p, Yap1p) but also cell growth and division (Gcr4p, Ste12p, Sok2p), and these TFs were most likely controlling the response at the post‐transcriptional level.
