compact almost complex submanifolds of complex Lie groups 
Does there exist any complex Lie group $G$ such that there are some positive-dimensional compact almost complex submanifolds (for example, $\mathbb{C}P^m$) of $G$? 

I want to get some examples. 
This is motivated by the following Corollary 1.21 from Complex Manifolds,
Lecture Notes written by Clemens Koppensteiner (link)
Proposition 1.20 (Generalization of Liouville's theorem). Let $M$ be a compact [complex] manifold and $f$ a holomorphic function on $M$. Then $f$ is constant.
Corollary 1.21 There exist no compact complex submanifolds of $\mathbb{C}^n$ of positive dimension
Scan including the proofs:

 A: Any almost complex submanifold of any complex manifold is a complex submanifold, as the Nijenhius tensor is the pullback of the Nijenhuis tensor. So the interesting problem is always in the other direction: when can we find complex submanifolds of an almost complex manifold? Any compact connected complex Lie group is abelian, because it has trivial image in any holomorphic representation (by Liouville's theorem), and so has trivial image in the adjoint representation, and so commutes with all elements near the identity (apply the exponential map) and so will all elements. But compact abelian complex Lie groups are complex tori. Their connected subgroups are also complex tori. These are rare: generic complex tori have no positive dimensional complex torus subgroups. Look at Birkenhake and Lange, Complex Tori for more information.
A: Whatever almost complex submanifolds are, complex submanifolds should be a subclass. There are compact complex tori which admit complex sub-tori. One (natural) class of examples are given as follows: Consider a Riemann surface $\Sigma$ and its Jacobian $Jac,$ and a assume that there is a holomorphic double covering $\pi\colon \Sigma\to \Sigma'.$ wThen, by pulling back, you have a subtorus $Jac'\subset Jac$ and and also its $'complement'$ the Prym variety (of $\pi.$)
Another remark: you usually define complex hyper-surfaces as the zero locus of holomorphic  sections of holomorphic line bundles (and not as the zero locus of holomorphic functions).
