a Geographical distribution of Hap1, Hap5 and Hap6. N, north of China, S, south of China. The pie chart represents their frequency. b The working model of GmILPA1 regulating of plant height in Hap1/2/6 and Hap5. In Hap1/2/6, under the UV-B irradiation, GmILPA1 accumulation is induced at transcriptional and protein levels. GmGA2ox-like is ubiquitinated by GmILPA1 and GmUBL1, and GmILPA1 mediates the degradation of GmGA2ox-like, GmUBL1 enhanced the degradation of GmGA2ox-like. As a result, the increase of bioactive GAs content promoted the growth of soybean. In Hap5, under the UV-B irradiation, GmILPA1 accumulation is induced only at protein level, eventually leads to shorter plant height in Hap5. GA3 induces GmILPA1 protein accumulation both in Hap1/2/6 and Hap5.
