Plants are sessile organisms that are\u00a0permanently restricted to their site of germination. How do plants respond when they encounter environmental changes?\u00a0 It is known that the mechanisms utilized to respond to environmental changes are tightly coupled to those used during morphogenesis and development in plants. Plants are able to regulate growth direction, initiate new organs, and regenerate tissues to adapt to a changing environment.<\/p>\n\n\n\n

Current projects related to the environmental control of plant growth and development are:<\/p>\n\n\n\n

1. Pattern formation in plants: How are leaf venation patterns established in plants?<\/strong><\/p>\n\n\n\n

2. Asymmetric cell division: How is asymmetric cell division controlled in plants?<\/strong><\/p>\n\n\n\n

3. Regulation of plant growth and development through light and gravity signaling: How is the stem cell maintained by light and gravity signaling.<\/strong><\/p>\n\n\n\n

4. Regulation of plant growth and development through environmental stresses: Control of PIN cluster formation at the plasma membrane<\/strong>.<\/p>\n\n\n\n

5. Regulation of membrane dynamics upon environmental stresses: Control of VAN3 activity and localization upon biotic and abiotic stresses<\/strong>.<\/p>\n\n\n\n
