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 ...
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 ...
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%. ...
Marker-assisted improvement of grain protein content and grain weight in Indian bread wheat
The leading Indian wheat cultivar
‘HUW234’ produces grain with relatively low protein
content (GPC) and thousand grain weight (TGW).
Therefore, marker-assisted backcrossing was used to
improve these two important traits ...
Control of Helminthosporium leaf blight of spring wheat using seed treatments and single foliar spray in Indo-Gangetic Plains of Nepal
Four fungicides for seed treatments and one as foliar spray were tested in replicated field experiments in
a strip plot design to determine the effect of fungicides on Helminthosporium leaf blight (caused by
Cochliobolus ...
Genome wide association mapping of stripe rust resistance in Afghan wheat landraces
Mining of new genetic resources is of paramount importance to combat the alarming spread of stripe rust disease and breakdown of major resistance genes in wheat. We conducted a genome wide association study on 352 un-utilized ...
QTL mapping identifies a major locus for resistance in wheat to Sunn pest (Eurygaster integriceps) feeding at the vegetative growth stage
Sunn pest (Eurygaster integriceps Puton) is the most destructive insect pest of bread wheat and durum wheat in West and Central Asia and East Europe. Breeding for resistance at the vegetative stage of growth is vital in ...
Amplicon-based RNA interference targeting V2 gene of cotton leaf curl kokhran virus- burewala strain can provide resistance in transgenic cotton plants
The conserved coat or V2 gene of begomoviruses is responsible for viral movement in the plant cells. RNAi technology was used to silence V2 gene for resistance against these viruses in transgenic plants. The transformation ...
First Report of Chilli leaf curl virus and Associated Alpha- and Beta-satellite DNAs Infecting Nettle Weed (Urtica dioica) in Pakistan
Weeds act as reservoirs of begomoviruses and ‘‘mixing vessels’’ leading to emergence of new viruses that may infect crops once a susceptible host plant is introduced into an agro-ecological system. Owing to the importance ...
Genetic Diversity of Bread Wheat Lines Based on Agro-morphological Traits
Twenty spring bread wheat genotypes (G) from eleven research centers in Pakistan were included in national uniform wheat yield trial (NUWYT) conducted at the Agriculture Research Farm of The University of Agriculture, ...
