Nervously meet seed, highly regarded (8)
I believe the answer is:
esteemed
'highly regarded' is the definition.
'nervously meet seed' is the wordplay.
'nervously' is an anagram indicator.
'meet'+'seed'='meetseed'
'meetseed' with letters rearranged gives 'ESTEEMED'.
(Other definitions for esteemed that I've seen before include "Highly-valued" , "Respected and appreciated like customer" , "Prized" , "Meet seed being thought well of" , "Prestigious" .)
