With reference to agriculture in India, how can the technique of 'genome sequencing', often seen in the news, be used in the immediate future? 1. Genome sequencing can be used to identify genetic markers for disease resistance and drought tolerance in various crop plants. 2. This technique helps in reducing the time required to develop new varieties of crop plants. 3. It can be used to decipher the host-pathogen relationships in crops. Select the correct answer using the code given below:

Genome sequencing, the process of determining the complete DNA sequence of an organism's genome, has immense applications in agriculture:

1. Identify genetic markers for disease resistance and drought tolerance: By sequencing the genome, scientists can pinpoint specific genes or genetic markers associated with desirable traits like resistance to diseases or tolerance to abiotic stresses like drought. This allows for targeted breeding.

2. Reduce the time required to develop new varieties: Traditional breeding is time-consuming. Genome sequencing, combined with marker-assisted selection, allows breeders to rapidly identify and select plants with desired traits, significantly accelerating the development of new, improved crop varieties.

3. Decipher host-pathogen relationships: Understanding the genetic makeup of both the crop (host) and the pathogen (e.g., fungi, bacteria, viruses) allows researchers to identify genes involved in resistance or susceptibility. This knowledge is crucial for developing effective disease management strategies and breeding disease-resistant crops.

Therefore, all three statements correctly describe advantages of implementing genome sequencing in agriculture.
