Topic: Doubled Haploids - Technology advancements and applications
Abstract: Doubled haploids (DH) have been known in the literature for decades. Various methods of producing DHs have been employed widely for genetic gain in plant breeding programs for a few crops. Moreover, this provides a system for enhancing biological understandings in both breeding and plant cell biology. Most recently, haploids and DHs have been considered tools for incorporating targeted breeding in crop species. Past research focused on protocol developments using either chromosome elimination techniques or tissue culture methods. Advancements in technological space, especially in cell biology, engineering, and digital technologies, make it possible to envision rapid advancements in this space. A few examples will be discussed in this seminar.
Biography: Sreekala Chellamma received her Bachelor of Science in agriculture and her Master of Science in horticulture at Kerala Agricultural University in Thrissur, India, and her PhD in agriculture at the Indian Agricultural Research Institute, New Delhi. Her PhD focus was among the first research on exploiting heterosis for carotenoids in African marigold, which is highly valued today for animal field and its pharmaceutical value. She pursued her post-doctoral research as a research officer at the Temasek Life Sciences Laboratories in Singapore, a research fellow at the National Institute of Agrobiological Sciences, Japan, and as a biologist at Agriculture and AgriFood Canada. During this period, she worked on rice disease resistance, rice stress biology, and carotenoid metabolic engineering. She joined Dow Agrosciences in 2009 as a trait manager for canola and continued with similar roles in corn and cotton. She made key contributions to the development of the Enlist™ cotton trait that is currently in the market. Later she became the monocot transformation leader at Dow Agrosciences. Most recently, she assumed the discovery lead position at Corteva Agriscience, where her interest is using cell and reproductive biology to develop novel breeding technologies for crops of interest to Corteva.
