Not really, once he has collected it, it is part of his chakra. Its not coming in.
Unless he has Ma and Pa.
Yeah they is a disturting chakra flow to prevent gen plus sage mode is nature eyes can't cheat nature it also the reason why juubi can't be put under genjutsu..
Um. . . Since when???
Natural chakra is just a raw form of chakra gathered from the life energy of the surrounding wilderness. Collecting it has no affect on genjutsu whatsoever. Naruto can easily be put in a genjutsu while in sage mode, unless Fukasaku and/or Shima is assisting him.
And as for the part about Kurama mentioned above, that's much different. Although Kurama is a part of Naruto's chakra network itself, he is STILL a separate entity. He can break a genjutsu placed on Naruto because he HIMSELF can disrupt the chakra flow and snap Naruto out of it.
Hope that answers your question.
Nope you are wrong. If this was the case, Kabuto wouldn't have decided to shut his eyes when fighting Sasuke and Itachi. Moreover, Naruto won't be able to meditate, concentrate and intake senjutsu chakra while he is under a genjutsu.
To break genjutsu, chakra from a separate entity must be put in the system of the one who is under the effects of genjutsu. Nature chakra is being drawn in at the same constant rate so to disturb the chakra network, that rate needs to change.
Kabuto never expected Itachi to break free of edo tensei. He was grooming himself to fight against Sasuke.Kabuto was afraid of Itachi's Tsukoyomi, coz that's on a different level.

If you change your chakara flow, then that stops genjutsu, that is exactly what happens when one is absorbing nature energy to "refill" senjutsu chakara or change from base to sage modeSM doesnt constantly absorb chakra, so that cant happen. Genjutsu isnt chakra shooting at enemy, one uses chakra to affect the senses (if needed) nothing more.
