| The objective of this study was to identify restriction fragment length polymorphism (RFLP) markers linked to QTLs that control aluminum (Al) tolerance in maize. The strategy used was bulked segregation analysis (BSA) and the genetic material utilized was an F2 population derived from a cross between the Al-susceptible inbred line L53 and Al-tolerant inbred line L1327. Both lines were developed at the National Maize and Sorghum Research Center - CNPMS/EMBRAPA. The F2 population of 1554 individuals was evaluated in a nutrient solution containing a toxic concentration of Al and relative seminal root length (RSRL) was used as a phenotype measured tolerance. The RSRL frequency distribution was continuous, but skewed towards Al-susceptible individuals.... |

| A toxicidade por Al em plantas se dá de várias maneiras, sendo a inibição do crescimento radicular uma das primeiras a se expressar, embora não seja prontamente perceptível em razão do hábito de crescimento das raízes. O objetivo desse trabalho foi avaliar a tolerância da erva-mate ao Al por meio do crescimento de raízes de mudas submetidas a doses crescentes do elemento. Para isso, testaram-se, três clones (C1, C2 e C3), doses de 100, 500, 1.000 e 2.000 μmol L-1 de Al (AlCAlCl36H2O) e um controle sem Al. Após 50 dias, determinaram-se massa seca das raízes, comprimento e volume total do sistema radicular, comprimento e volume total das raízes em diferentes diâmetros. O Al influenciou positivamente o crescimento das raízes de todos os clones. O maior... |

| Relating environmental factors to species occurrence is a fundamental step in a better understanding of the community structure, the spatial and temporal dynamics of populations and how species may respond to environmental changes. In this paper, we used phytoplankton occurrence data, from a French national phytoplankton monitoring network, and environmental variables with the aim of characterizing the realized ecological niches of phytoplankton groups. We selected 35 phytoplankton taxa representing the most important taxa in terms of occurrence frequency and abundance along the French coast of the eastern English Channel, the Southern Bight of the North Sea and the Atlantic Ocean. We show that environmental variables such as nutrient concentration, water... |
