Name the source organism of the gene cry IAc and its target pest.
Answers
target pest:cotton ball worms
Source of gene cry lAc is Bacillus thuringiensis
Bacillus thuringiensis (Bt) is a unique bacterium in that it shares a common place with a number of chemical compounds which are used commercially to control insects important to agriculture and public health. Although other bacteria, including B. popilliae and B. sphaericus, are used as microbial insecticides, their spectrum of insecticidal activity is quite limited compared to Bt. Importantly, Bt is safe for humans and is the most widely used environmentally compatible biopesticide worldwide. Furthermore, insecticidal Bt genes have been incorporated into several major crops, rendering them insect resistant, and thus providing a model for genetic engineering in agriculture.
Its target pest-cotton bollworms.
The cotton bollworm (or corn earworm or sorghum headworm) is a serious pest in the southern cotton growing areas. In Kansas cotton, infestations are sometimes observed, although damage has been limited even when high infestations have developed in corn and grain sorghum. However, the potential for economic damage exists, and growers should watch for developing infestations during fruiting and boll development. The adult is a medium-sized, cream-colored moth and is seen frequently throughout the day during periods of heavy infestations. Moths lay eggs singly, mostly on the young terminal leaves and sometimes on leaves and squares within the canopy
