Histidine limitation alters plant development and influences the TOR network.

ABSTRACT: Plant growth depends on growth regulators, nutrient availability, and amino acid levels, all of which influence cell wall formation and cell expansion. Cell wall integrity and structures are surveyed and modified by a complex array of cell wall integrity sensors, including leucine-rich repeat (LRR)-extensins (LRXs) that bind RALF (rapid alkalinization factor) peptides with high affinity and help to compact cell walls. Expressing the Arabidopsis root hair-specific LRX1 without the extensin domain, which anchors the protein to the cell wall (LRX1ΔE14), has a negative effect on root hair development. The mechanism of this negative effect was investigated by a suppressor screen, which led to the identification of a sune (suppressor of dominant-negative LRX1ΔE14) mutant collection. The sune82 m
