Herbicide resistant weeds have long been an issue for countries that rely on herbicides for weed control. Several choices of hand sprayers can provide adequate coverage on trees. Increasingly, resistance evolves due to mechanisms limiting herbicide reaching target sites. High doses of 2,4-D, however, can produce muscular and neurological symptoms (Table 1). strain CP4. expressing the protein that activates expression of these genes all the time in plants. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.
