It is important that Maria should send her resume immediately.
Is 'send' in the sentence a bare infinitive or a plural verb?
The sentence is an It cleft. IT means the sentence is cleaved into two:
It (empty subject without referent) is important (main clause) + Maria should send her a letter (sub clause).
Let us get back to business.
Take a look at the bolded sub clause:
The V element is realized by a finite verb phrase in the subjunctive mood: 'should send'. The operator 'should' is the finite verb, so 'send' is non-finite.
'(S)end' being non-finite (bare infinitive) means it does not show person. Consequently, there is no useful purpose in talking about its number, is has none. No plural, no singular.
Note that the putative 'should' may be dropped, in which case 'send' becomes finite, and its number agrees with the 3rd person singular subject Maria.
I go, he goes, Maria goes, we go, they go.
I should go, he should go, Maria should go, we should go, they should go.
You'll notice that the forms of modal+bare infinitive are regular and invariant.
The present subjunctive 'send' is finite because it shows tense (non-past), although it does not show person.
The indicative 'sends' is finite too, and it shows both tense and person.
eng, I think I have learnt something. Subjunctives are a distinct set of verb forms to express modality; they are inflections of the non-finite VP in non-finite subordinate clauses.
EDIT: Or in main clauses: "Long live the king!"
