Transcriptome Analysis of Rice Seedling Roots in Response to Potassium Deficiency

Abstract Rice is one of the most important food crops in the world, and its growth, development, yield, and grain quality are susceptible to a deficiency of the macronutrient potassium (K+). The molecular mechanism for K+ deficiency tolerance remains poorly understood. In this study, K+ deficient co...
