Global climate change combined with asymmetric warming can have detrimental effects on the yield of crop plants such as rice (Oryza sativa L.). Little is known about metabolic responses of rice to high night temperature (HNT) conditions. Twelve cultivars with different HNT sensitivity were used to investigate metabolic changes in the vegetative stage under HNT compared to control conditions. Ce...

The first commercially successful F1 hybrid sweet corn, Golden Cross Bantam, was released by Smith in the early 1930s (17). Today, over 600 sweet corn hybrids are available commercially in the United States and thousands of new hybrids are developed and evaluated each year. These hybrids display a wide range of phenotypic reactions to prevalent diseases (9), indicating a considerable amount of ...

fire blight disease caused by erwinia amylovora is a destructive disease of pome fruits including apple worldwide. use of resistant cultivars is the most efficient method of disease control. in the present research, we investigated genetic resistance of 89 local and imported commercial apple cultivars in natural contaminated conditions to the bacterial disease using beltsville scoring system (u...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2002, 55% of Arkansas’ cotton acreage was planted to a stacked-gene cu...

Conventional and genetically modified (GM) maize cultivars have been widely planted in Brazil to produce grains for processed food, feed, or to be consumed fresh as corn ears. This study used real-time PCR to detect GM maize in processed products and fresh commercial corn ears produced in the last two years in South Brazil. Eighteen conventional and GM maize cultivars were obtained from seed pr...

Identity recognition systems allow plants to tailor competitive phenotypes in response to the genetic relatedness of neighbours. There is limited evidence for the existence of recognition systems in crop species and whether they operate at a level that would allow for identification of different degrees of relatedness. Here, we test the responses of commercial soya bean cultivars to neighbours ...

background : lindane is an insecticide which is used in commercial insecticides and food containers. caseâ presentation : herein, we reported on a 62-year-old man with liver cirrhosis 12 years after continuous exposure to lindane gas.the diagnostic workup showed no other possible cause, and findings of liver scintigraphy and clinical manifestations were compatible with substance-induced cirrhos...

Wheat flour quality is an important consideration in the breeding and development of new cultivars. A strong association between high-molecular weight glutenin subunits (HMW-GS) and bread making quality has resulted in the widespread utilization of HMW-GS in wheat breeding. In this study, we analyzed 242 lines of wheat, including landraces from the provinces of Punjab and Baluchistan, as well a...
