RNA extraction from dry seed
 

It's hard to beat the modified hot borate buffer developed for RNA
extraction from cotton seeds by Wan & Wilkins: Analytical Biochemistry:
223(1): 7-12.

Also check the citing papers for further modifications significantly
simplifying their protocol, especially Wu et al. (Plant Molecular Biology
Reporter. 20(3): 213-218) I routinely extracted intact, high-purity RNA
from various plant tissues with the hot borate buffer.
