This work establishes local existence and uniqueness as well as blow-up criteria for solutions
 $(u,b)(x,t)$
of the Magneto–Hydrodynamic equations in Sobolev–Gevrey spaces
 $\dot{H}^s_{a,\sigma}(\mathbb{R}^3)$
. More precisely, we prove that there is a time
 $T>0$
such that
 $(u,b)\in C([0,T];\dot{H}_{a,\sigma}^s(\mathbb{R}^3))$
for
 $a>0, \sigma\geq1$
and
 $\frac{1}{2} . If the maximal time interval of existence is finite, $ 0\leq t < T^* $, then the blow–up inequality $ \frac{C_1\exp\{C_2(T^*-t)^{-\frac{1}{3\sigma}}\}\;\;\;\;\;\;\;}{\;\;\;\;(T^*-t)^{q}\;\;\;\;} \;\;\;\;\;\;\;\;\;\;\leq \|(u,b)(t)\|_{\dot{H}_{a,\sigma}^s(\mathbb{R}^3)} \quad \mbox{with}\,\, q = {\frac{2(s\sigma+\sigma_0)+1}{6\sigma}} $holds for $ 0\leq t
,
 $a>0$
,
 $\sigma> 1$
(
 $2\sigma_0$
is the integer part of
 $2\sigma$
).
