SRS8599865 SAMN18492123 Plant sample from Zea mays subsp. mays 381124 Zea mays subsp. mays The strength of the stalk rind, measured as rind penetrometer resistance (RPR), is an important contributor to stalk lodging resistance. To enhance the genetic architecture of RPR, we combined selection mapping on populations developed by 15 cycles of divergent selection for high and low RPR with time-course transcriptomic and metabolic analyses of the stalks. cultivar Missouri Second Cycle Stiff Stalk Synthetic dev_stage V8 stage geo_loc_name USA tissue leaf sub_species mays BioSampleModel Plant
