Root nitrate transporters expression and localization in tomato respond differently to soil yeasts with ACC deaminase activity or indole-3-acetic acid synthesis

Key Points

• Nitrate transporters in tomato plants display varied expression based on soil yeast type.
• Soil yeasts with ACC deaminase activity increased transport while those synthesizing indole-3-acetic acid varied responses.
• The analysis focuses on root localization of transporters in relation to different yeasts present in soil.
• Findings suggest that soil yeasts may play an essential role in nutrient uptake in tomatoes.
