We investigate the spatially-resolved star formation main sequence instar-forming galaxies (SFGs) using Integral Field Spectroscopic (IFS)observations from the Mapping Nearby Galaxies at the Apache Point Observatory(MaNGA) survey. We demonstrate that the correlation between the stellar masssurface density ($\Sigma_*$) and star formation rate surface density($\Sigma_{\mathrm{SFR}}$) holds down to sub-galactic scale, leading to theSub-Galactic Main Sequence (SGMS). By dividing galaxies into two populationsbased on their recent mass assembly modes, we find the resolved main sequencein galaxies with 'outside-in' mode is steeper than that in galaxies with'inside-out' mode. This is also confirmed on a galaxy-by-galaxy level, where wefind the distributions of SGMS slopes for individual galaxies are clearlyseparated for the two populations. When normalizing and stacking the SGMS ofindividual galaxies on one panel for the two populations, we find the innerregions of galaxies with 'inside-out' mode statistically exhibit a suppressionin star formation, with a less significant trend in the outer regions ofgalaxies with 'outside-in' mode. In contrast, the inner regions of galaxieswith 'outside-in' mode and the outer regions of galaxies with 'inside-out' modefollow a slightly sub-linear scaling relation with a slope $\sim$0.9, which isin good agreement with previous findings, suggesting that they are experiencinga universal regulation without influences of additional physical processes.
