Fig. 1From: Characterization of the rice NLA family reveals a key role for OsNLA1 in phosphate homeostasisPhylogenetic relationships of NLA proteins and OsNLA family expression patterns in rice. a Unrooted phylogenetic tree of the NLA family using MEGA 5.10 by the neighbor-joining method. Dicots: Vitis vinifera (GSVIV), Glycine max (Glyma), Malus domestica (MDP), Medicago truncatula (Medtr), Arabidopsis thaliana (At); monocots: Brachypodium distachyon (Bradi), Sorghum bicolor (Sobic) and Setaria italica (Si). OsNLA family expression patterns in rice. b, c Spatial expression of OsNLAs transcripts. Transcript levels for OsNLA1 (b) and OsNLA2 (c)in leaf sheath, leaf blade, roots and shoot base in 30-d-old seedlings grown in nutrient solutions containing 300 μM Pi and in panicle before flowering. Expression of OsNLA1 and OsNLA2 is relative to OsACTIN2. d, e Transcript levels of OsNLA1 (d) and OsNLA2 (e) in root and shoot of plants grown for 10 d in nutrient solutions with different Pi concentrations. Data represent mean ± SD of three replicates. Different letters represent significant differences according to Duncan’s multiple range test (P < 0.05)Back to article page
