Ph.D. in Molecular Biology and Biotechnology


Department of Plant Biotechnology, Centre for Plant Molecular Biology & Biotechnology is one of the oldest institutes in India to offer PhD in Biotechnology from 1991. It has good repute and the PhD degree is internationally recognized. Biotechnology is utilization of living organisms and their derivatives for the betterment of human life. Genetic improvement of plants is essential to feed the ever-growing population coupled with the declining land resources, global warming and vagaries of monsoon. Modern molecular biology methods combine the techniques from plant breeding, plant physiology, plant biochemistry, recombinant DNA technology, gene editing, “omics” based technologies and other allied fields to impart specialized characters to plants – called Plant Biotechnology.

Future Career

M.Sc. (Agriculture) in Biotechnology students are admitted through JNU Common Entrance Examination in Biotechnology (CEEB) which was replaced by the Graduate Aptitude Test – Biotechnology (GAT-B) from the year 2020. Generally, JNU-CEEB/ GAT-B toppers prefer CPMB&B, TNAU as one of their primary priority institutes during the selection process. Apart from JNU students, ten students are admitted  through TNAU entrance examinations. Apart from this, students are also admitted through NTA-AIAEE-PG entrance exam under the ICAR quota.

Doctoral Courses

After admission the students undergo a set of courses that help them understand the basics of Molecular Biology and Biotechnology as per the Choice Based Credit System (CBCS) with a total of 25 credits, of which 2 credits are seminar. The courses include major, minor, supporting and some non-credit compulsory courses.

Doctoral thesis research

After completing the courses in the first year, the students start their thesis research for 75 credits exclusively earmarked for their Thesis Research. Each student is assigned to an experienced faculty, approved by the Dean of School of Post-Graduate Studies, who would guide the student on his/ her choice of research topic.


Research internship

The students are exposed to several scientific events like industrial/ institutional visits, workshops, symposia and conferences. Many are encouraged to have internship training at other institutes for a couple of months, either in India or abroad.

Alumni Experience

It was a fantastic learning experience at the Department of Plant Biotechnology, TNAU Coimbatore. A solid foundation is required for success, and the Department of Plant Biotechnology has assisted me in laying one. The faculty at the Department were outstanding, and the laboratory facilities are excellent. I am grateful to all of the faculty members who have always encouraged and assisted me in overcoming my weaknesses. Thank you, CPMB&B, TNAU, for moulding me into the person I am today and providing me with professors who genuinely cared about my success.

Kambale Rohit Dilip,

I am Bharathi completed Ph.D in biotechnology in the Department of Plant Biotechnology, Centre for plant molecular biology and Biotechnology, Tamil Nadu Agricultural University, Coimbatore. This campus has provided me the excellent learning environment for the studies. The learning and research experience gained from CPMB & B has a significant role in shaping my career. It has helped me to learn from different institutes through collaboration with other universities and institutes and also knowledge on all the research activities and also all the field related experiences also. It has provided very good infrastructure that enables us to explore many research areas. It has given exposure to a diverse range of perspectives and has taught me the value of collaboration and teamwork.
