ABSTRACT-During rice growing season, the symptomless rice seeds from different paddy fields in Guilan province, Iran, were collected. After isolation of epiphytic and endophytic bacteria, 39 isolates including 19 epiphytes and 20 endophytes were selected based on the predominant characteristics. Five Operational Taxonomic Units (OTUs) were obtained based on PCR-RFLP of 16S r-DN...
Knowledge and information related to all aspects of crop-pest system are the foundations on which modern pest management decisions are based. The transfer of research and extension information to farmers plays the key role in the adoption of integrated Pest Management (IPM). FuzzyXPest is proposed to provide information to the farmers and researchers through the Internet using fuzzy expert syst...
Areas and spatial distribution information of paddy rice are important for managing food security, water use, and climate change. However, there are many difficulties in mapping paddy rice, especially mapping multi-season paddy rice in rainy regions, including differences in phenology, the influence of weather, and farmland fragmentation. To resolve these problems, a novel multi-season paddy ri...
Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...
in this paper, the value of exchange rate was calculated in order to determine comparative advantage in crops of sari township during 2009-2010. hence, first, comparative advantage indices are estimated by using a policy analysis matrix. the results showed that just wheat has a drc index of one in the minimum amount of national currency exchange rate value. this indicated the fact that only whe...
