Azed 2466 Last One (Hopefully) + Parsing Queries

[JJ109]

28a Girl filled with love – what Cliff sought early on? (5) BIO(S) _
Nb I am not 100% sure of the "S"

The S comes from 16d Indicator of smoker’s intake? Poisonous stuff holds it up (8)
C _ TI _ I _ E. I think this is CYTISINE but can't fully parse.

Others
5d Deity bishop removed from mosque niche (about time) (6) MI _ _ RA
I think this is MITHRA, a Persian deity, but can't parse

12a Tissue frameworks giving support –second’s folded in layers (8) _ (T)R _ GATA
I think this is STRIGATA but can't see how to get the "IG"

6a What Trump’s opponents call him, crudely: ‘Low, grabbing advantage’ (6, 2 words)
I think this is BUP A.SS (UP/advantage) "inside" BASS (low), but have not heard the expression "bup ass" Bad ass parses but then 7d where I have "pegboard" would have to begin with a D and I think pegboard is correct.

Thanks for your help

12a) Stromata, mo = second, folded in strata

//Stromata definition, the supporting framework or matrix of a cell//

[emeritus]

12 Stromata ?

[iminoz]

6a BAD ASS, advantage, AD in BASS, low

7d DAMBOARD, draughts board.
DAM restrain flow + BARD, poet around O

[iminoz]

16d COTININE, marker for exposure to tobacco smoke
TI in CONINE, poisonous material
I thought 28a may be BIONT, O in Lady, a girl. Not sure about the rest.

[iminoz]

....that was meant to be B.I.N.T, a girl must have been considered inappropriate.

Many thanks everyone - you get a couple of answers in your head and it throws you out for others!

[JJ109]

Mihrab is the Mosque niche - B( bishop)= mihra + T(ime) = MITHRA

[Hagen]

28 has got to be BIONT from the wordplay, but I don't get the definition at all. Are we looking at Cliff Richard here? I can't see a relation to any of his early songs.

[stephem]

BIONT = living organism so maybe a reference to Living Doll?

[Hagen]

I wondered about that myself but it's a hell of a stretch! Seems unlikely for Azed, who always plays fair. Still, I can't come up with anything better...
