Although modern agriculture has heavily relied on nitrogen fertilization, typically less than half of the applied nitrogen is taken up by crops, with the remainder lost to the environment and causing serious environmental issues. Therefore, there is an urgent need to develop plant science-based knowledge to enable the reduction of nitrogen fertilizer inputs. In natural environments, nitrogen availability is generally low and subject to substantial temporal and spatial fluctuations. Moreover, multiple environmental factors, such as temperature, light, and the availability of other nutrients, fluctuate simultaneously. To survive under such fluctuating environmental conditions, plants have evolved adaptive mechanisms to optimize nitrogen acquisition and utilization. Our research group aims to elucidate the molecular mechanisms underlying these adaptive responses and to advance scientific understanding toward sustainable agriculture.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<hr \/>\n<h4><span style=\"color: #555555;\"><strong>Latest publications<\/strong><span style=\"font-size: small;\"> (for complete and most current publications visit <a href=\"https:\/\/kibataba.wixsite.com\/website-e\">group pages<\/a>)<strong><br \/>\n<\/strong><\/span><\/span><\/h4>\n<p>(1)Ortega-Villaiz\u00e1n A.G., King E., Patel M.K.
