The primary research interest of my lab lies in understanding the hormonal regulation of plant growth and development under optimum condition and various stresses. For this, we are primarily focusing on the plant hormone auxin, which influences plant behavior from embryogenesis to senescence and exhibits a complex interaction with other hormones. Interestingly, the hormonal interactions are centered on auxin and primarily target the auxin transport as shown in the image. Based on this model, we hypothesize that the regulation of growth and development under stressed condition depends on the cellular auxin gradient and this gradient also regulates the hormonal cross talk. Currently, we are investigating this hypothesis from different perspectives. Using a combinatorial approach of physiology, genetics, molecular biology and cell biology my lab is currently focusing on: 1) Understanding the role of auxin in regulating temperature stress mediated growth and development 2) Understanding the molecular cross talk between actin and hormones during meristem development 3) Elucidating the regulatory/ molecular mechanism of 2,4-D induced change in cytoskeletal structure and its impact on selective herbicidal action on monocots and dicots 4) Understanding the role of actin dynamicity in determining the plant’s response to auxin 5) Elucidating the molecular pathway of IBA response in plant development 6) Understanding the molecular mechanisms of cadmium and caesium toxicity in plants to engineer hyperaccumulator plants for phytoremediation
