i also think the wood release might be a recessive trait that could be traced back to the shinju.i cant say whether or not it originated in hashirama and was not possessed by any other senju.but i agree with bob1200 that its a (albeit recessive) gene passed down via hagoromo or kaguya from the shinju itself.even though it might not be identical to 'shinju wood' it shares some characteristics as previously mentioned.one being absorbing chakra and subjugating bijuu,which is completely unrelated to regular wood and trees.i therefore believe mokuton is the manifestation of an ancestral trait dating back to the shinju,hagoromo or kaguya that has mutated over time into a watered-down state ,much like the sharingans descent from the rinnegan/juubi eye.thats just what i think.

and ithink fact that its made up of basic elements doesnt disprove its possible relation to the shinju.even trut-seeking balls are partially made of the basic natures

its might also be possible that mokuton itself is an ordinary kekkei genkai ,that although rare ,has manifested in the senju clan before hashirama,and maybe its hashiramas godly life-force and ashura yang chakra that gives his mokuton its unusual properties.an obvious one being subjugating bijuu.and perhaps their powerful lifeforce and the fact they were grown from chakra makes them naturally absorb chakra to grow.perhaps for these reasons hashiramas version of mokuton was the most memorable ,and the memory of the original,much weaker technique faded into obscurity.just another theory though.i still think mokuton has originated from some ancestral influence.i mean its basically creating a living organism out of the basic elements.thats a bit hax for a KG made of just two elements.while its more believable if it were inherited from shinju ,kaguya hagoromo or ashura.or if the ashura yang chakra in hashirama and his cells provides the lifeforce for a basic living organism to be created
