DESCRIPTION:Juan Alonso-Serra's talk title: Hydraulic patterns in plant de
 velopment\n\nAbstract: \nPlant cells undergo dynamic changes in water stat
 us during normal development\, generating hydraulic patterns and water flu
 xes at the tissue level. These processes are particularly evident\, for ex
 ample\, when shoot meristems produce a new flower. While water fluxes are 
 often regarded as passive by-products of development\, growing evidence su
 ggests that they not only result from growth processes but also play an ac
 tive role in shaping them. In my research\, I integrate 4D confocal micros
 copy\, water tracing techniques\, hydraulic modeling\, and genetics to inv
 estigate how water fluxes serve as both a consequence and a driver of grow
 th patterning. By uncovering the feedback loops between water movement and
  morphogenesis\, we can uncover how hydraulic signals actively influence p
 lant development and contribute to the regulation of growth and form. \n\n
 \nAna Patricia Ramos's talk title: Forming an Eye: from cell behaviour to 
 tissue shape changes.\n\nAbstract: \nBuilding an organ is a multistep proc
 ess in which correct morphogenesis arises from feedback loops between gene
 tic regulation and mechanical forces. A key morphogenetic event is the eme
 rgence of tissue curvature\, which is essential for various developmental 
 processes\, such as gastrulation\, and shapes multiple organs\, including 
 the heart and neural tube. \n\nCurvature can develop alongside other cellu
 lar and tissue rearrangements. In many of these complex contexts\, the bio
 mechanical interactions driving curvature remain unclear\, as the contribu
 tions of individual rearrangements and their interplay are difficult to di
 sentangle. \n\nTo address this\, we investigated the morphogenesis of the 
 vertebrate optic cup\, a highly curved structure that forms from a flat bi
 layered optic vesicle. Using zebrafish as a model system\, where cell and 
 tissue dynamics can be studied in native 4D conditions\, we combined in vi
 vo experiments\, 4D segmentation and analysis\, and theoretical modeling. 
 This interdisciplinary approach allowed us to identify key players driving
  the emergence of optic cup curvature.
