This study demonstrates the combinatorial management of multiple pests through a trans-acting siRNA (tasiRNA)-based micro RNA-induced gene silencing (MIGS) strategy. Transgenic cotton events demonstrated improved efficacy against cotton leaf curl disease, cotton leaf hopper and root-knot nematode. Cotton (Gossypium hirsutum L.

Unlabelled: Insect pests are one of the major biotic stresses limiting yield in commercially important crops. The lepidopteran polyphagous spotted pod borer, causes significant economic losses in legumes including pigeonpea. RNA interference (RNAi)-based gene silencing has emerged as one of the potential biotechnological tools for crop improvement.
View Article and Find Full Text PDFCotton is a commercial crop of global importance. The major threat challenging the productivity in cotton has been the lepidopteron insect pest or cotton bollworm which voraciously feeds on various plant parts. Biotechnological interventions to manage this herbivore have been a universally inevitable option.
View Article and Find Full Text PDFBackground: Occurrence of multiple biotic stresses on crop plants result in drastic yield losses which may have severe impact on the food security. It is a challenge to design strategies for simultaneous management of these multiple stresses. Hence, establishment of innovative approaches that aid in their management is critical.

However, recalcitrance of economically important crops to tissue culture-based organogenesis ensues a setback in the use of transgenesis in the genetic engineering of crop plants. The present study developed an optimized, genotype-independent, nonconventional tissue culture-independent strategy for the genetic transformation of flax/linseed.

Management of pod borer, Helicoverpa armigera has been prominent among crop improvement programs. Lack of resistance sources in the cultivated germplasm and crossing incompatibility with pod borer-resistant wild relatives have prompted biotechnological interventions.

Cotton ( L.), a mercantile crop plant, is grown worldwide for fiber and seed oil. As with other economically important crops, cotton is bogged down with many biotic and abiotic stress factors.
View Article and Find Full Text PDFPlants are challenged incessantly by several biotic and abiotic stresses during their entire growth period. As with other biotic stress factors, insect pests have also posed serious concerns related to yield losses due to which agricultural productivity is at stake. In plants, trait modification for crop improvement was initiated with breeding approaches followed by genetic engineering.

Glyphosate [-(phosphonomethyl)glycine] is a widely used broad spectrum non-selective herbicide that controls weeds by inhibiting 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme and interfering with the shikimate biosynthesis pathway. Cotton ( L.

One of the major constraints in the production of pigeonpea is a polyphagous insect pest, Helicoverpa armigera. Non-availability of resistant sources in the germplasm and limitations in conventional breeding have been key factors for continued yield losses.

Protein engineering of ICPs is a competitive alternative for resistance management in insects. The primary focus of the study was to reiterate the translational utility of a protein-engineered chimeric Cry toxin, Cry1AcF, for its broad spectrum insecticidal efficacy using molecular modeling and docking studies.
