Coniothyrium minitans (CM) is hyperparasitic to Sclerotinia sclerotiorum (SS), a pathogen of many economically important crops. In this paper, we describe the isolation of improved mutants of CM, using a UV - irradiation regime, with altered chitinase production and tolerance to high concentration of iprodione, which are effective against SS. Three out of the 59 mutants obtained inhibited the mycelial growth of CM. Infectivity of sclerotia by the new mutants was assayed by the plant-tissue-based system using carrot segments. More than 80% of sclerotia were colonized by the mutants and the wild-type CM. The mutant strains retained ability to produce significant amounts of chitinase. The mutants differed from their wild-type strain in appearance, morphology and sporulation. In conclusion, the results presented here provide evidence that the new biotypes of C. minitans are effective in controlling S. sclerotiorum.

Prepared by ECLAC for the twelfth session of the Regional Conference on Women in Latin America and the Caribbean, this document systematizes and describes various dimensions that shape the way the region's women participate in the labour market and how they access and use the different elements of the digital economy. Information and communications technologies (ICTs); provide essential support across all economic, political, cultural and social activity, as well as being a production sector in their own right. As such, they are potential allies in the drive to achieve equality by helping reduce the gender inequities which constitute not only a gender digital gap but also a social divide. Public policies on gender equality must take into account the key and interconnected dimensions of economy, well-being and technology if they are to be capable of providing an ambitious and innovative response to the challenges of today's society. The core argument in the reflection on ICTs and gender equality thus has to do with how women engage in processes of change and sustainable development in the countries, which cannot be achieved without equal participation by men and women. From this perspective, the gender digital gap offers a specific opportunity to tackle gender inequalities in the region.

Prefacio Prepared by ECLAC for the twelfth session of the Regional Conference on Women in Latin America and the Caribbean, this document systematizes and describes various dimensions that shape the way the region's women participate in the labour market, and how they access and use the different elements of the digital economy. Information and communications technologies (ICTs) provide essential support across all economic, political, cultural and social activity, as well as being a production sector in their own right. As such, they are potential allies in the drive to achieve equality by helping reduce the gender inequities which constitute not only a gender digital gap but also a social divide. Public policies on gender equality must take into account the key and interconnected dimensions of economy, well-being and technology if they are to be capable of providing an ambitious and innovative response to the challenges of today's society. The core argument in the reflection on ICTs and gender equality thus has to do with how women engage in processes of change and sustainable development in the countries, which cannot be achieved without equal participation by men and women.

Le document aborde le débat sur le changement structurel et la place des femmes dans la société de l’information, ainsi que la capacité de développement de leur autonomie dans le cadre de la mise en place d’un nouveau paradigme technologique. Il dresse un bilan de la situation des femmes sur le marché de l’emploi et passe en revue, sur la base des données des enquêtes disponibles, les indicateurs d’accès à et d’utilisation de l’Internet de façon à mesurer les écarts existants entre hommes et femmes dans différentes sphères sociales et géographiques.

This paper aims to develop guidelines for the collective and semi-presence-based implementation of (a situation in which there is no active participation of a consultant specialist in the company) certifiable management systems. These systems include ISO 9001, ISO 14001, or OHSAS 18001. This is a theoretical and conceptual study which was based on four practical experiences of the theory of collective and semi-presence-based system implementation for the development of the guidelines proposed. These guidelines are drawn up according to the following items: selection of companies; awareness, diagnosis, planning, training, implementation, verification and improvement.
