As　multi-gene　networks　transmit　signals　and　products　by　synchronous　cooperation,　investigating　the　synchronization　of　gene　regulatory　networks　may　help　us　to　explore　the　biological　rhythm　and　internal　mechanisms　at　molecular　and　cellular　levels.　We　aim　to　induce　a　type　of　fractional-order　gene　regulatory　networks　to　synchronize　at　finite-time　point　by　designing　feedback　controls.　Firstly,　a　unique　equilibrium　point　of　the　network　is　proved　by　applying　the　principle　of　contraction　mapping.　Secondly,　some　sufficient　conditions　for　finite-time　synchronization　of　fractional-order　gene　regulatory　networks　with　time　delay　are　explored　based　on　two　kinds　of　different　control　techniques　and　fractional　Lyapunov　function　approach,　and　the　corresponding　setting　time　is　estimated.　Finally,　some　numerical　examples　are　given　to　demonstrate　the　effectiveness　of　the　theoretical　results.　(c)　2020　Elsevier　Ltd.　All　rights　reserved.
