The introduction of genes isolated from different Bacillus thuringiensis strains to express Cry-type toxins in transgenic crops is a common strategy to confer insect resistance traits. This work intended to extensively in silico analyse Cry1A(b)16 protein for the identification of peptide markers...

This paper presents the results of a study conducted to determine the response of E. biplaga larvae to Bt cotton in South Africa. Two rearing colonies of E. biplaga were established. Larvae were collected from an experimental cotton field at Potchefstroom, and moths were collected with light traps...

The biological potential of Vip and Cry proteins from Bacillus is well known and widely established. Thus, it is important to look for new genes showing different modes of action, selecting those with differentiated entomotoxic activity against Diatraea flavipennella and Elasmopalpus lignosellus,...

Fusarium verticillioides is one of the main pathogens of maize, causing ear and stalk rots. This fungus is also able to produce high levels of fumonisins, which have been linked to various illnesses in humans and animals. Previous studies have shown that maize hybrids genetically modified with the ...

The insecticidal Cry1Ab protein expressed by transgenic (Bt) maize can enter adjacent water bodies via multiple pathways, but its fate in stream ecosystems is not as well studied as in terrestrial systems. In this study, we used a combination of field sampling and laboratory experiments to examine...

Cotton-wheat is an important cropping system in South Asia. Introduction of BT cotton has caused the time conflict between sowing of BT cotton and wheat harvest in this cropping system. Wheat is harvested in late April but the best planting time of BT cotton is mid-March, which indicates a time...

Transgenic Bt cotton has gained great ecological and economic benefits after application in research and production for over 20 a, but the resistance risk of cotton boll worm is also increasing gradually. Therefore, exploration of Bt genes by different insecticidal mechanism can not only improve...

Since the birth of transgenic crops expressing Bacillus thuringiensis (Bt) toxin for pest control, the public debate regarding ecological and environmental risks as well as benefits of Bt crops has continued unabated. The impact of Bt crops, especially on non-target invertebrates, has received...

Greater than expected injury by western corn rootworm (WCR) (Diabrotica virgifera virgifera LeConte) to Cry3Bb1 expressing maize hybrids (Zea mays L.) has been reported in southwestern Nebraska. Affected areas of some fields are often associated with high pH calcareous soils where maize growth is...

A field experiment was carried out to assess the Cry protein expression in Bt cotton hybrids as influenced by nutrient management based on target yield under medium deep black soils at the Main Agricultural Research Station, Dharwad, Karnataka during kharif, Rabi season of 2012-13 and 2013-14 under ...
