Figure 1Characterizations of TaMPKKK18-3B

(a) ClustalW alignment results among TaMPKKK18-3B and its plant counterparts. Conserved motifs specified by ATP binding site, activation site, polypeptide substrate binding site, activation loop (A-loop), and STKc_MAPKKK are highlighted. (b) Simulated three-dimensional structure of the TaMPKKK18-3B protein. (c) GFP signals detected inN. benthamianaepidermal cells harboring fusionTaMPKKK18-3B-GFP. Arrows point to the GFP signals derived from the nucleus.

Figure 5Phenotypes and plant agronomic traits ofTaMPKKK18-3B,TaMPKK1.2-6B,TaMPK2-1DandTaNAC2-5Btransgenic lines

(a)-(d)Phenotypes of transgenic lines at seedlings stage treated by low-P stress. (e)-(h) Plant biomass of transgenic lines at the mid-grain filling stage. (i)-(l) Grain phenotypes of transgenic lines at maturity. (m)-(p) Yields of transgenic lines under field-deprivation conditions. WT, wild type. In (a)-(d), plants were cultured at growth chamber supplied by 0.05 mM Pi. In (e)-(h) and (m)-(p), data presented are means ± standard deviation (n = 3). Student′st-test was used to test the statistical significance (*P<0.05) between the transgenic lines and WT under deficient-P conditions.
