Plant cell having heterologous polynucleotides, plant or part of plant, transgenic seed, method for controlling lygus

摘要

Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a pest from the Lygus genus, is capable of decreasing the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides from specific polypeptide families as disclosed herein, or active variants thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest. Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. Plants, plant parts, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.
