摘      要：Climate change is increasing the frequency of extreme heat events that aggravate its negative impact on plant development and agricultural *** experiments designed to study plant adaption to heat stress apply homogeneous high temperatures to both shoot and ***,this treatment does not mimic the conditions in natural fields,where roots grow in a dark environment with a descending temperature *** high temperatures severely decrease cell division in the root meristem,compromising root growth,while increasing the division of quiescent center cells,likely in an attempt to maintain the stem cell niche under such harsh ***,we engineered the TGRooZ,a device that generates a temperature gradient for in vitro or greenhouse growth *** root systems of plants exposed to high shoot temperatures but cultivated in theTGRooZ grow efficiently and maintain their functionality to sustain proper shoot growth and ***,gene expression and rhizosphere or root microbiomecomposition are significantly less affected in TGRooZ-grown roots than in high-temperature-grown roots,correlating with higher root *** data indicate that use of the TGRooZ in heat-stress studies can improve our knowledge of plant response to high temperatures,demonstrating its applicability from laboratory studies to the field.
