dc.description.abstractRoot hairs (RH) as a mixed tip- and non-tip growing protrusions that develop from root 39 epidermal cells are important for nutrient and water uptake, root anchoring, and interaction 40 with soil microorganisms. Although nutrient availability and temperature are critical interlinked 41 factors for sustained plant growth, the molecular mechanisms underlying their sensing and 42 downstream signaling pathways remain unclear. Here, we identified a moderate low 43 temperature (10°C) condition that triggers a strong RH elongation response involving several 44 molecular components of the auxin pathway. Then, we have determined that auxin 45 biosynthesis carried out by YUCCAs/TAA1, the auxin transport conducted by PIN2/PIN4 and 46 AUX1/PGP4, and the auxin signaling controlled by TIR1/AFB2 coupled to four specific ARFs 47 (ARF6/ARF8 and ARF7/ARF19), are all crucial for the RH response at moderate low 48 temperature. These results uncover the auxin pathway as one central hub under moderate low 49 temperature in the roots to trigger RH growth. Our work highlights the importance of moderate 50 low temperature stimulus as a complex nutritional signal from the media soil into the roots that 51 may be fine-tuned for future biotechnological applications to enhance nutrient uptake.
