The role of maize (Zea mays) radicle root hairs in seedling establishment under adverse phosphorus and water seedbed conditions.

ABSTRACT:

Background and aims

A vigorous root system is crucial for maize seedling establishment. Its formation and subsequent plant performance are hindered by nutrient and water deficiency. Upon germination, maize seedlings develop primary, then seminal roots, covered with pubescent root hairs. The functions of root hairs at this developmental stage remain largely unknown. This study examined their role during phosphorus (P) and water limitations during early seedling development at the physiological, elemental and molecular level, comparing a roothairless maize mutant (rth3) and its isogenic wildtype (WT).

Methods

Shoot and root system architecture phenotyping and elemental analysis were performed on 5-d-old rth3 and WT plants experiencing various P- and water-deficient conditions
