How to beat the heat: Memory mechanism allows plants to adapt to heat stress
Memory mechanism plants JUMONJI Heat stress
font style='font-size:12px;'>
2021/8/4
Researchers have found that plants adapt to heat stress via a specific 'memory' mechanism. The JUMONJI family of proteins can control small heat shock genes, allowing plants to become heat tolerant fo...
Exploring Trends in Microcrack Properties of Sedimentary Rocks: An Audit of Dry and Water Saturated Sandstone Core Velocity–Stress Measurements
