Fig. 1From: Genome-wide identification of Aux/IAA gene family in white clover (Trifolium repens L.) and functional verification of TrIAA18 under different abiotic stressPhylogenetic analysis representing the relationship between IAA proteins in white clover, Arabidopsis, and M. truncatula. IAA subgroups (classifications I, II, III, IV, V) are marked with different colors. The phylogenetic tree was drawn using the neighbor-joining (NJ) method with a bootstrap value of 1000Back to article page
