Abstract:Phosphorus is an essential macronutrient for plant growth and development. In response to phosphate (Pi) deficiency, plants rapidly produce a substitutive amount of root hairs; however, the mechanisms underlying Pi supply for root hair growth remain unclear. Here, we observed that soybean (Glycine max) plants maintain a consistent level of Pi within root hairs even under external Pi deficiency. We therefore investigated the role of vacuole‐stored Pi, a major Pi reservoir in plant cells, in supporting root hair… Show more
