Paula is a phD working at INTA (National Institute for Agricultural Research, similar to INRAE in Argentina) in the Sunflower Genomics and Ecophisiology Lab at the Biotechnology Institute there, she is also a researcher at National Council for Science (CONICET, same as CNRS) and Professor at San Martin University.

Leaf senescence in sunflower: a complex trait studied by a systems biology approach

Leaf senescence in plants is the last stage of leaf development that is characterized by a decline in photosynthetic activity, an active degeneration of cellular structures and the recycling of accumulated nutrients to areas of active growth such as buds, young leaves, flowers , fruits and seeds. This process holds economic significance as  it can impact  yield, influencing the plant´s ability  to maintain an active photosynthetic system during prolonged periods, especially during the grain filling stage, which  affects plant weight and oil content. It also can be associated with different stresses or environmental conditions, manifesting itself widely in a context of climate change and limiting yield, especially in crops of agronomic relevance. In this work we study the stability of two widely putative "stay-green" well-characterized sunflower genotypes belonging to the INTA Breeding Program against differential N conditions, in order to verify their yield stability in control conditions and under N supply.
