sunn pest (eurygaster integriceps put.) is one of the major pests of wheat in iran. identification of resistantcultivars is an effective integrated pest management (ipm) strategy. to identify the genetic response of wheat and triticale to sunn pest, and determine the relationship between resistance and morpho physiological traits, eight bread wheat breeding lines/cultivars, four durum wheat lin...

Lulo (Solanum quitoense Lam.) is a fruit tree of Andean origin national economic importance in Colombia, which constitutes an important source employment for farmers and their families. Vascular root wilt caused by the fungus Fusarium oxysporum one most limiting diseases production this species, causing low yields considerable losses. As effective control alternative pathogen, identification ge...

maize genotypes were screened for host resistance and seed treatment chemicals were evaluated in field to manage fusarium ear rot complex of maize at high- and mid-hill environments in nepal during 2003 and 2004. seven popular maize genotypes along with a susceptible check were used in the host resistance study. the maize genotypes adopted from exotic sources, manakamana-3 and deuti, performed ...

Of 59 clinical isolates of Enterobacter cloacae from a teaching hospital in Sichuan, China, 18 isolates were shown to be resistant to oxyimino cephalosporins and aztreonam. Enterobacterial repetitive consensus PCR revealed that these isolates comprised 7 distinct genotypes. The presence of plasmids in the 18 clinical isolates was revealed by conjugational transfer of plasmids from E. cloacae to...

melon (cucumismelo) production is significantly affected by fusarium wilt worldwide. the pathogen, fusariumoxysporum f. sp. melonis race 1 (fom1) causes serious economic losses in iran. to find resistance sources of melon, 45 local genotypes and breeding lines, collected from different parts of iran, were screened against race 1 of fom. seedlings were inoculated with a suspension of 1×106 conid...

background and objectives: septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph s. tritici) is currently the most serious disease of wheat worldwide. this study was established to determine the function of resistant genes of m. graminicola to find out the number of genes corresponding in resistant reaction and also to estimate the genetic parameters of resistance. mater...

BACKGROUND Hepatitis B infection, caused by hepatitis B Virus (HBV), is one of the major global public health problems. Hepatitis B Virus genotypes appear to show varying geographic distribution with possible pathogenic and therapeutic differences. Knowledge of HBV genotypes is very important for clinical treatment. Lamivudine is a nucleoside analogue that is clinically used to treat chronic he...
