Morphology of wild-type and lrt1 root systems. Wild type (A–C) and mutant lrt1 (D–F) plants grown under various growth conditions for 16 days. Compared with wild-type plants (A), no LR emergence was observed in lrt1 plants (D) cultivated in moist paper. In contrast, LRP emerged in aerated hydroponics (wild-type, B; lrt1, E) and non-aerated hydroponics (wild-type, C; lrt1, F), respectively. In non-aerated hydroponics, mutants (F) displayed signs of decay, illustrated by brownish roots. The majority of LRs in lrt1 mutants (E, F) terminated their growth during or shortly after emergence. Scale bars = 10 mm.
