Rhizophagy Cycle and Endophytes in Plants with Dr. James White
Dr. White discusses how plants absorb endophyes from soils in order to extract nutrients from them. In this process, called Rhizophagy (Rhizo = root, Phagy = eating), bacteria and fungi cycle between a free-living phase in the soil and a plant-dependent phase within cells of plant roots. He explains how plants internalize nitrogen-fixing bacteria into their tissues and spread the bacteria throughout the plant in order to get nitrogen from the microbes to different parts of the plant. Plants need microbes to grow properly and get the nutrients they need out of soil.

just a small gardener with some land outside austin, lets go!!!
Welcome, and thank you for joining us today! We hope you enjoy and learn new information about the Rhizophagy cycle in plants!
Dr. White will join us today at 11am PT for the live panel discussion with him, Charles Dowding, and Dr. Elaine. It is going to be a good one! James will also be on a Meet & Greet at 12:10pm, join and ask him your questions directly!
Great presentation thank you so much
I’m not getting any play on James White
I also am not getting anything. Black screen, no sound, time running.
This cycle makes tremendous sense for regen farming. Curious if the same process occurs in hydroponics or aquaculture for instance if roots are in rockwool or submerged in deep water culture?
If there are minimal root hairs does that mean the cycle is down-regulated?
It’s working!
mind blowing, must rewatch later!! LOVE THIS.
so would rhizophagy cycle explain that planting the same crops over time with these methods would yield Better?
can fungi can also influence the root growth?
Great talk. So informative. I enjoyed learning how roots interact with bacteria and how sterile roots leads to plant death. This was really fascinating, especially seeing the videos in real time. I was able to take lots of great notes. Thank you for the presentation.
Thank you so much
As a seed producer i have always thought that farm-raised seed carried the local microbes over to following years. Can you speak more about this. Maybe what types of microbes could be existing inside seed coats. And why bio regional organic non treated seeds would benefit soil systems

Not excatly an answer but might be interesting
fascinating James white…actually mind blowingly interesting
Really interesting!!!
Thanks!!!
All VERY new information for me! I will watch this many times to get the best understanding that I can. So grateful for these presentations for those of us who love to learn, but could never afford an education, living on a very low income. Blessings, Valerie Adame
Heard him talk before, but this was much more textured information. Thank you!
Are there any in-the-field tests to assess the presence of Rhizophagy cycle?
I presume. Do you have root hairs? Considering the rest was only discovered recently then it’s probably a bit tricky in the field
Outstanding info Jim – eyeopening.
A great team

Wow, that was super helpful and really interesting! I had a quick question–you mentioned about how microorganisms can modulate the development of seedlings. As far as we/you know, is this intervention of the microorganisms modulating the development of most seedlings, or is it only known the modulate the development of certain specific species’ seedlings?
I ask because I can see clearly from the research you presented how the microorganisms are involved with the elongation of established plants’ root systems. But I am very curious about how they are operating on the development of seedlings! Thanks!
Exciting addition to our Soil Food Web training is understanding the microbial processes in detail. Reinforces the need to understand, cultivate, and care for soil microbes.
What amazing additional discoveries have been made in the past few years! Thank you so much for the mind-blowing update!
I am ever more awed by the intricate beauty of the natural processes fuelling life on our planet..
I would like to review the process of n-fixation more slowly so i can absorb better? I would love copies of the relevant citations if possible. Totally amazing presentation!
Thanks Norman
A couple questions come to kind about 10min in (if you answer later in presentation feel free to disregard): 1) Are the bacteria and fungi being pulled in through the vacuum created by evapotranspiration? I find all the phenomena based on evapotranspiration fascinating and practically miraculous!
2) Does seed inoculation with the “best microbes” get at part of why seeds are such great sources of fertility, which we can use in formulating ideal compost? I always figured seeds were great fertilizer or compost material because the plant wanted to provide its progeny with ample nutrients, like a bird with its eggs, but the addition of beneficial microbes would be a multiplier of that benefit. Very cool stuff!
Bacteria and fungi have been on earth for about 4.5 Billion years ago, and plants have been on earth for 700 thousand years to 1 Billion years, more or less. So the bacteria and fundi have rule the earth and seem to set the ground rules for plants. Very interesting talk.
Thank you but I will need to watch again to become more familiar to understand better.
Beautiful descriptions, very helpful slides and graphics. It shows how much intelligent
exchange takes place between plants and microbes so that each gets what they need.
Thank you.
Thank you for a lovely presentation.
Thank you. I will definitely watch this again. Much has been discovered since I studied soils 45 years ago.
I was your student in mycology at Rutgers in 1997 or 1998. One of my favorite classes of all time. I’m so happy to see you here.
Trichomes might be for nitrogen fixation instead of/in addition to plan defense?!? Wow, did not expect that.
I really enjoyed all he had to share.
Amazing! Thank you!
James White, sincere thhttps://2023.soilregensummit.com/wp-login.php?action=logout&redirect_to=https%3A%2F%2F2023.soilregensummit.com%2Fevents%2Frhizophagy-cycle-and-endophytes-in-plants-with-dr-james-white%2F&_wpnonce=ef744664e3anks. You need to keep your hands off your beard.
Does synthetic fertilizer applications effect the Rhizophagy cycle? Does synthetic fertilizer applications replace superoxide if conditions for superoxide is poor?
Fascinating cutting edge information.
I appreciate your humble and refreshing recognition of all those who have worked with you to reveal these processes.
Wonderful information. Thank you for all your great work and for sharing it.
Thank you for explaining all at a level most people can understand. Beautiful explanatory slides. Fascinating information.
Thanks to you and your team also.
Thank you for all the information and all the amazing work that you and your team are doing!!
this presentation is truely revelationary stuff!
Often you see and follow a scientist outlining research and breakthroughs with great visuals and information, however, this presentation is so simply presented and built that when you view the video clips that validate the findings it is so obviously true. In life simplicity is mastery and there is no doubt that mastery is on full display in Dr James Whites’ style.
On a practical note – i will be now paying extra attention to addressing ground compaction in landscape resoration efforts; Got to have that superoxide functioning or else i am wasting my time..
This was amazing information, thank you from Trinidad.
