Fig. 3From: Identification of drought-responsive miRNAs and physiological characterization of tea plant (Camellia sinensis L.) under drought stressNucleotide bias at each position of Camellia sinensis conserved miRNAs under different drought stress conditions. Drought stress conditions were as follows: a normal water supply, b mild drought stress, c moderate drought stress, and d severe drought stress. X-axis represents miRNA nucleotide positions; y-axis indicates percentage of each specific nucleotide at each nucleotide position. Brown, green, red, and blue correspond to guanine (G), cytosine (C), adenine (A), and uracil (U), respectivelyBack to article page
