It's kind of the brightest star for instance to turn up (5)

I believe the answer is:

genus

I'm a little stuck... Click here to teach me more about this clue!

'it's kind' is the definition.
(a genus is a kind or type of something)

'brightest star for instance to turn up' is the wordplay.
'brightest star' becomes 'sun' (the Sun is a star. I am not sure about the 'brightest' bit.).
'for instance' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'to turn up' shows that the letters should be reversed in order.
'sun'+'eg'='suneg'
'suneg' backwards is 'GENUS'.

'of the' is the link.

Can you help me to learn more?

(Other definitions for genus that I've seen before include "Part of the family" , "Biological group containing one or more species" , "Category above species (Biology)" , "Kind or sort of" , "Latin class?" .)

I've seen this clue in The Globe and Mail.
