Plant viruses: exploiting agricultural and natural ecosystems.

Grand Challenge in Plant Virology: Understanding the Impact of Plant Viruses in Model Plants, in Agricultural Crops, and in Complex Ecosystems

THE 2007 FRAZIER-ZAUMEYER LECTURE Bean Improvement Cooperative 50^^ Anniversary Meeting, Madison, WI FROM RALPH CORBETT'S BEAN FIELD TO MOLECULAR DETAILS OF BROAD SPECTRUM POTYVIRUS RESISTANCE

Genetic resistance to plant viruses has been used for at least eighty years to control agricultural losses to viral diseases. To date, hundreds of naturally occurring genes for resistance to plant viruses have been reported from studies of both monocot and dicot crops, their wild relatives and the plant model, Arabidopsis. While viruses are relatively simple genetic entities and much progress h...

Importance of protecting the natural reproduction of kutum (Rutilus kutum Kamenskii, 1901) in exploiting the ecological carring capacity of the ecosystem

251 specimens of kutum fish caught by bony fish persine on the southern shores of the Caspian Sea (Mazandaran) during the years 2017-2019 were studied to study the growth trend of this species. In this study, maximum estimated length (L∞) and annual growth coefficient (K) of kutum fish were estimated 71.79 cm and 0.13, respectively. The results of natural reproduction of this species in Kheirud...

Modelling Mediterranean agro-ecosystems by including agricultural trees in the LPJmL model

In the Mediterranean region, climate and land use change are expected to impact on natural and agricultural ecosystems by warming, reduced rainfall, direct degradation of ecosystems and biodiversity loss. Human population growth and socioeconomic changes, notably on the eastern and southern shores, will require increases in food production and put additional pressure on agro-ecosystems and wate...
