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.
