Plants monitor changes in ambient temperature by the red (R) and far-red (FR) photoreceptor, phytochrome B (phyB) 18, 19. Therefore, a molecular understanding of how plants sense and respond to temperature has become critical to the development of strategies for sustaining crop production in a changing climate 17. Increases in global temperature have already had major impacts on plant phenology, distribution, diversity, and are expected to significantly decrease crop productivity 15, 16. These phenomena are collectively called thermomorphogenesis 13, 14. Besides the stress-tolerant responses induced by extreme freezing or scorching conditions 1– 3, changes in the range of ambient growth temperatures (12–27 ☌ for Arabidopsis 4) can also dramatically alter the rate of shoot and root growth and thereby plant architecture 5, 6, adjust cell differentiation patterns and developmental transitions such as reproductive organ formation 7– 9, and modulate plant immunity 10– 12. Temperature is a critical environmental cue influencing all aspects of plant development and growth.

Our results thus provide direct cell biology evidence supporting an early temperature signaling mechanism via dynamic assembly/disassembly of individual photobodies possessing distinct thermostabilities.

Surprisingly, elevated temperatures inflict opposite effects on phyB’s functions in the hypocotyl and cotyledon despite inducing similar photobody dynamics, indicative of tissue/organ-specific temperature signaling circuitry either downstream of photobody dynamics or independent of phyB. The thermostability of photobodies relies on phyB’s photosensory module. Increases in temperature from 12 ☌ to 27 ☌ incrementally reduce photobody number by stimulating phyB-FP disassembly from selective thermo-unstable photobodies. Our results demonstrate that warm temperature elicits different photobody dynamics than those by shade. Here we report temperature-dependent photobody localization of fluorescent protein-tagged phyB (phyB-FP) in the epidermal cells of Arabidopsis hypocotyl and cotyledon. At the cellular level, shade antagonizes phyB signaling by triggering phyB disassembly from photobodies. Now the movement of U with dial indicator when changin gY direction is 0.04 and X is 0.Warm temperature is postulated to induce plant thermomorphogenesis through a signaling mechanism similar to shade, as both destabilize the active form of the photoreceptor and thermosensor phytochrome B (phyB).

M569 P2 S1 X physical drive 0 goes backwards Then tried on 234 and 2 is not working, then defined this: Drives So I put 3Z motors on P1,2,3 and the motor on 2 is not energized, then moved the motors to 0,1,2 and it is working, but center motor is inverted (2), So I make it to move in the right direction with inverted motor, but when G32 it is corecting wrong direction, I do not know why I ordered a new Duet wifi and while waiting today decided to try to move 3 Z motors on wifi and x,y,u on DUEX board. So today I made quite a few experiments chasing my problem with moving of the U carriage during printing with X.Ī few days ago I tried to put both Y motors on ZA and ZB conectors, just to find that one of my Z connectors is not energizing the motor. Instead he found and fixed the problem in a matter of days and released 3.2.2. The firmware is referred to as RepRapFirmware for Duet 3 - Duet 3 is the name for the hardware line, not the firmware.Īnd the fact that it works on a Duex 5 is pretty convincing to me.Īlso the way the Duet 2 communicates with the Duex 5 is totally different from the way the Duet 3 boards communicate with one another.Īnd when I discussed the Duex 5 endstop sensor problems on my printer when running 3.2.0 with I think he would have mentioned that it wasn't supported. I hope so, its kind of a lot of work to move things around. Its seems unclear to me if they are referring to Duet 3 hardware or Duet 3 firmware but they do say 'tool boards' which are only Duet 3 so I think you might be right. RepRapFirmware (as at version 3.3.1) for Duet 3 currently has the following limitations when tool boards or expansion boards are used.
