[Arabidopsis] mRNA and sRNA from seedlings

My lab has noticed a very poor efficiency for isolating both mRNA and small RNA from some tissues, while other tissues seem fine. We are using Invitrogen's (now Life Technologies) Trizol product. As far as we can tell, there are abundant mRNA and sRNA before the isolation, but the Trizol seems to select for long non-mRNA. Invitrogen says the tissue shouldn't matter, but experimentally we see that it does. Can anyone suggest an RNA prep that can work from ANY tissue (seedling, seed, etc...), isolate all small RNAs (20-25nt), and recover a high percentage of the longer mRNAs?

Thank you,
