GmWRKY81 Encoding a WRKY Transcription Factor Enhances Aluminum Tolerance in Soybean.

ABSTRACT: Aluminum (Al) toxicity is an essential factor that adversely limits soybean (Glycine max (L.) Merr.) growth in acid soils. WRKY transcription factors play important roles in soybean responses to abiotic stresses. Here, GmWRKY81 was screened from genes that were differentially expressed under Al treatment in Al-tolerant soybean Baxi10 and Al-sensitive soybean Bendi2. We found that GmWRKY81 was significantly induced by 20 μM AlCl₃ and upregulated by AlCl₃ treatment for 2 h. In different tissues, the expression of GmWRKY81 was differentially induced. In 0-1 cm root tips, the expression of GmWRKY81 was induced to the highest level. The overexpression of GmWRKY81 in soybean resulted in higher relative root elongation, root weight,
