Supplementary Fig. 7: Correlation between the natural variation of NRT1.1B and nitrogen-related functions in indica and japonica populations.
From: NRT1.1B is associated with root microbiota composition and nitrogen use in field-grown rice
(a–e) The natural variation in NRT1.1B in indica and japonica populations is correlated with nitrogen-related functions in root microbiota from indica and japonica populations, including nitrite ammonification (a) (P = 2.2 × 10–16 in field I; P = 1.8 × 10–12 in field II, two-sided t-test), nitrate reduction (b) (P = 1.1 × 10–13 in field I; P = 2.1 × 10–8 in field II, two-sided t-test), respiration of nitrate (c) (P = 2.2 × 10–16 in field I; P = 6.1 × 10–13 in field II, two-sided t-test), nitrite respiration (d) (P = 2.4 × 10–16 in field I; P = 7.2 × 10–13 in field II, two-sided t-test) and nitrogen respiration (e) (P = 2.2 × 10–16 in field I; P = 6.8 × 10–13 in field II, two-sided t-test). NRT1.1Bindica harbors a “T” at 980 bp downstream of the ATG start codon and NRT1.1Bjaponica harbors a “C” at the same position, resulting in an amino acid substitution (p. Met327Thr). The numbers of replicated samples are as follows: in field I, indica (n = 192), japonica (n = 86); in field II, indica (n = 192), japonica (n = 87).
