Effect of cultivation systems on maize productivity and production profitability

In the past decades maize was produced on the largest scale in Hungary. The extreme weather conditions and the rising energy prices of the last years forced the farmers to produce with the least input and with the highest yield stability possible. Our research was carried out on the land of Vásárhelyi Róna Kft. where a 9-hectare area was partitioned for three equal parcels. The three parcels were cultivated with different basic cultivating methods: ploughing, loosening and strip tillage. Nine-nine different maize hybrids were sowed in each cultivated parcels. In the course of the research we examined the moisture content of the soil, the morphologic features of the hybrids and average yield by hectares. We calculated the total cost, theoretical incomings and earnings by growing maize per hectare. According to our one-year research we came to the result that the most productive method was tilling proceeding even though it had the highest cost. On the other hand we found that the hybrids reacted differently to the various cultivation procedures. Realizing the results we suggest farmers should take notice of rational tilling and the importance of choosing hybrids

DAAM is required for thin filament formation and Sarcomerogenesis during muscle development in Drosophila.

During muscle development, myosin and actin containing filaments assemble into the highly organized sarcomeric structure critical for muscle function. Although sarcomerogenesis clearly involves the de novo formation of actin filaments, this process remained poorly understood. Here we show that mouse and Drosophila members of the DAAM formin family are sarcomere-associated actin assembly factors enriched at the Z-disc and M-band. Analysis of dDAAM mutants revealed a pivotal role in myofibrillogenesis of larval somatic muscles, indirect flight muscles and the heart. We found that loss of dDAAM function results in multiple defects in sarcomere development including thin and thick filament disorganization, Z-disc and M-band formation, and a near complete absence of the myofibrillar lattice. Collectively, our data suggest that dDAAM is required for the initial assembly of thin filaments, and subsequently it promotes filament elongation by assembling short actin polymers that anneal to the pointed end of the growing filaments, and by antagonizing the capping protein Tropomodulin
