Germination of Immature Bean Seeds
You don't need to understand all the biochemistry to make practical use of this information. It answers a question which pops up periodically. "Will seeds germinate if they are not fully mature when harvested?"

Reprogramming of Protein Synthesis from a Developmental to a Germinative Mode Induced by Desiccation of the Axes of Phaseolus vulgaris.

Immature seeds of Phaseolus vulgaris cv Taylor's Horticultural removed from the pod at 32 days of development do not germinate unless first subjected to desiccation. Our results show that premature drying not only redirects metabolism from a developmental to a germination program but it does so permanently, thus effecting an irreversible switch. This is shown by in vitro protein synthesis, and analysis of poly(A)(+) mRNA with a cDNA probe specific for phaseolin message. For example, the pattern of proteins synthesized in vitro by the mRNA fraction from fresh and prematurely dried axes show strong similarities; on the other hand, the mRNA population from rehydrated axes code for a different set of proteins. Also, the message for phaseolin is preserved following the normal maturation process and premature desiccation of seeds. Following rehydration of immature seeds at the desiccation-tolerant stage, this message is no longer detectable in the axes.
