Differential toxicity of antifungal protein AFP against mutants of Fusarium oxysporum

Antifungal protein (AFP) from Aspergillus giganteus was assayed for toxicity against the Fusarium oxysporum wild-type strain and mutants in genes involved in cell signaling (ΔpacC, pacCc Δfmk1) or cell-wall biogenesis (ΔchsV, Δchs7, Δgas1). The mutants were classified into two groups according to their sensitivity to AFP: ΔpacC, Δgas1 and Δchs7, which were significantly more resistant to AFP than the wild-type, and pacCC, Δfmk1 and ΔchsV, which were more sensitive. Western blot analysis revealed increased binding of AFP to the three resistant mutants, ΔpacC, Δgas1 and Δchs7, but also to ΔchsV, indicating that differential binding may not be a key determinant for sensitivity. Addition of Ca2+ or K+ dramatically reduced antifungal activity and binding of AFP, suggesting that these cations compete for the same targets as AFP at the surface of the fungal cell.

La organización y atención a la diversidad en centros de educación secundaria de Iberoamérica. Reflexiones y experiencias

La organización y atención a la diversidad en centros de educación secundaria de Iberoamérica. Reflexiones y experiencias" es el nuevo título de la Serie Informes de RedAGE. La misma recoge la visión de 41 especialistas de 13 países iberoamericanos sobre la realidad y perspectivas de la atencion a la diversidad en centros de educación secundaria. La focalización, en esta etapa educativa, tiene que ver con la consideración de que, actualmente, es el momento de la escolarización donde se producen más abandonos y donde se abren o limitan posibilidades para el posible acceso a estudios superiores de los más capacitados. La orientación de los escritos tiene que ver con las finalidades y objetivos de la Red de Apoyo a la Gestion Educativa (RedAGE); también con el convencimiento, por parte de los que escriben, de que el contexto organizativo actúa como un amplificador o limitador de las actuaciones dirigidas a la formación de los escolares

Gender Gap in Parental Leave Intentions: Evidence from 37 Countries

Despite global commitments and efforts, a gender-based division of paid and unpaid work persists. To identify how psychological factors, national policies, and the broader sociocultural context contribute to this inequality, we assessed parental-leave intentions in young adults (18–30 years old) planning to have children (N = 13,942; 8,880 identified as women; 5,062 identified as men) across 37 countries that varied in parental-leave policies and societal gender equality. In all countries, women intended to take longer leave than men. National parental-leave policies and women’s political representation partially explained cross-national variations in the gender gap. Gender gaps in leave intentions were paradoxically larger in countries with more gender-egalitarian parental-leave policies (i.e., longer leave available to both fathers and mothers). Interestingly, this cross-national variation in the gender gap was driven by cross-national variations in women’s (rather than men’s) leave intentions. Financially generous leave and gender-egalitarian policies (linked to men’s higher uptake in prior research) were not associated with leave intentions in men. Rather, men’s leave intentions were related to their individual gender attitudes. Leave intentions were inversely related to career ambitions. The potential for existing policies to foster gender equality in paid and unpaid work is discussed.Gender Gap in Parental Leave Intentions: Evidence from 37 CountriespublishedVersio
