New Delhi: Prime Minister Narendra Modi on Thursday expressed grief at the death of eminent scientist MS Swaminathan and said his groundbreaking work in agriculture transformed lives of millions and ensured India's food security.

Swaminathan (98), also known as the father of Green Revolution in India, died on Thursday due to age-related illness. He is survived by three daughters.

"Deeply saddened by the demise of Dr MS Swaminathan Ji. At a very critical period in our nation's history, his groundbreaking work in agriculture transformed the lives of millions and ensured food security for our nation," Modi said in a post on X (formerly Twitter).

The prime minister further said,"Beyond his revolutionary contributions to agriculture, Dr. Swaminathan was a powerhouse of innovation and a nurturing mentor to many. His unwavering commitment to research and mentorship has left an indelible mark on countless scientists and innovators."

Modi said he would always cherish his conversations with Swaminathan and added that his passion to see India progress was exemplary.

"His life and work will inspire generations to come. Condolences to his family and admirers. Om Shanti," Modi wrote.

An era of agricultural research, education and extension marked by disruptive innovations has come to an end with the death of MS Swaminathan, Indian Agricultural Research Institute (IARI) Director A K Singh said on Thursday.

 "In passing away of Prof. Swaminathan, ends an era of agricultural research, education and extension that was full of disruptive innovation. If God appears to poor and hungry in form of bread as said by Mahatma Gandhi, that God is Dr. Swaminathan who should be worshipped by every citizen while taking daily meals," Singh said in a statement.
