| Popis | In the past decades, the average annual temperatures have arisen due to global warming. High ambient temperatures shorten the life cycles of many crops, reducing the grain yield. Periods of extreme weather also have a negative effect on crop production, affecting the development and viability of both female and male gametes, causing heat-induced sterility and reducing the receptivity to stigma to pollen, pollen tube growth in the stigma and style and ovule penetration. The plant reproductive development has been suggested to be the most sensitive stage to heat stress. Auxin and cytokinin are the most important hormones involved in the regulation of plant development, including the correct development of seedpod, ovule, seed and embryo. Heat Shock Factors (HSFs) mediates the heat shock response. There are 21 HSF in Arabidopsis thaliana, and they have been linked to regulate the hormone production during heat stress. The aim of this project is to unravel the role of heat at the bioproduction, transport and signaling during embryo development in Arabidopsis thaliana, focusing in the interactive network of HSFs during heat stress. |
