A transgenic approach to control hemipteran insects by expressing insecticidal genes under phloem-specific promoters
The first generation transgenic crops used strong constitutive promoters for transgene expression.
However, tissue-specific expression is desirable for more precise targeting of transgenes. Moreover,
piercing/sucking ...
Massive Shift in Gene Expression during Transitions between Developmental Stages of the Gall Midge, Mayetiola Destructor
Mayetiola destructor is a destructive pest of wheat and has six developmental stages. Molecular mechanisms controlling the transition between developmental stages remain unknown. Here we analyzed genes that were expressed ...
RNA Interference based Approach to Down Regulate Osmoregulators of Whitefly (Bemisia tabaci): Potential Technology for the Control of Whitefly
Over the past decade RNA interference (RNAi) technology has emerged as a successful tool not only for functional genomics, but in planta expression of short interfering RNAs (siRNAs) that could offer great potential for ...
Selection of new high yield potential bread wheat lines resistant to Hessian fly, Mayetiola destructor (Say), in Morocco
Wheat (Triticum sp.) is the main staple food of the Moroccan population. However, the
crop is attacked by several pests and diseases. Hessian fly is the most serious pest, causing
an average yield loss of 30% yearly. In ...
Two small secreted proteins from Puccinia triticina induce reduction of ß-glucoronidase transient expression in wheat isolines containing Lr9, Lr24 and Lr26
Little is known about the molecular interaction of wheat and leaf rust (Puccinia triticina Eriks). However, genomic tools are now becoming available so that the host-pathogen interactions can be better understood. Significant ...
Role of crop competition in managing weeds in rice, wheat, and maize in India: A review
In India, the three staple food crops viz., rice, wheat, and maize, contribute more than four-fifths of the
total food grain production. Among the several factors limiting their productivity, weeds account for
about 40%. ...
Reduction of Winter Wheat Yield Losses Caused by Stripe Rust through Fungicide Management
Stripe rust of winter bread wheat (Triticum aestivum L.) causes substantial grain yield loss in Central Asia. This study involved two replicated field experiments undertaken in 2009–2010 and 2010–2011 winter wheat crop ...
Identification and Characterization of Salt Tolerance of Wheat Germplasm Using a Multivariable Screening Approach
Salinity is one of the major limitations to wheat production worldwide. This study was designed to evaluate the level of genetic variation among 150 internationally derived wheat genotypes for salinity tolerance at ...
Measurement of the total factor productivity and its determinants: the case of the wheat sector in Tunisia
The main objectives of the current study are to quantify the Total Factor Productivity (TFP) growth of durum wheat sector in Tunisia and to identify its main determinants. The Malmquist index approach was applied for the ...
Growth in Total Factor Productivity in the Egyptian Agriculture Sector: Growth Accounting and Econometric Assessments of Sources of Growth
This research aims to assess the Total Factor Productivity (TFP) of the whole agricultural sector in Egypt for the period 1961-2012 using Törnqvist index calculations. Particularly, it aims to investigate: (1) the most ...
