Summary Report: National Evaluation of Learn and Serve America

In 1993, the Nalional and Community Service Trust Act (PL. 103-82) established the Learn and Serve America School and Community-Based Programs to support school and Community-Based efforts to involve school-aged youth in community service. The Learn and Serve program is administered by the Corporation for National Service and funded through grants to states and national organizations, and through them to individual school districts, schools, and community organizations. In 1994-95, the first year of the program, the Corporation awarded approximately $30 million in grants supporting over 2,000 local efforts involving over 750,000 school-aged youth

Florigenic and Antiflorigenic Signalling in Plants

The evidence that FLOWERING LOCUS T (FT) protein and its paralog TWIN SISTER OF FT, act as the long distance floral stimulus, or at least that they are part of it in diverse plant species, has attracted much attention in recent years. Studies to understand the physiological and molecular apparatuses that integrate spatial and temporal signals to regulate developmental transition in plants have occupied countless scientists and have resulted in an unmanageably large amount of research data. Analysis of these data has helped to identify multiple systemic florigenic and antiflorigenic regulators. This study gives an overview of the recent research on gene products, phytohormones and other metabolites that have been demonstrated to have florigenic or antiflorigenic functions in plants
