Hello, I am about to expose brine shrimp cysts to 48v/mm DC electric field 
using batteries during their hatching for 2 days.However, I couldn't find a 
single article about effect of DC field on animals, unlike plants.
No significant change in the length of the seedlings was produced by DC field 
of 3600 V/m. AC fields of 3600 and 1800 V/m increase the average length of the 
seedlings by 12% and 8%, respectively. The insensitivity of  soy  seedlings  
to a pure electrostatic field can be explained by assuming that the  soy  is 
not electrotropic.(Costanzo, E 2008 The influence of an electric field on the 
growth of soy seedlings. Journal of Electrostatics)
White radish sprout exposed to static electric field of 2.5kV/m had 26% 
increase in germination rate and 60% increase in the length and 24% increase 
in the weight. Claims that the effect is due to stimulation of pythomone.
(Shimizu, N., Muramoto, Y., & Okumura, T. (2006). Acceleration of plant growth 
by D.C. electric field. IEIC Technical Report)
DC fields of 1, 1.5V/cm resulted in changes in the cellular pattern of the 
RAM. The field activated the quiescent centre (QC): the cells of the QC 
penetrated the root cap junction, disturbing the organization of the closed 
meristem and changing it temporarily into the open type. Even a weak electric 
field disturbs the pattern of cell divisions in plant root meristem. This in 
turn changes the global organization of the RAM. A field of slightly higher 
strength also damages root cap initials,terminating their division. (Influence 
of a Weak DC Electric Field on Root Meristem Architecture, WOJCIECH WAWRECKI 
and BEATA ZAGORSKA-MAREK)
I was inspired because of Der Urzeit Code.  This claims that DC field during 
the germination or hatching,organism grew into its "primeval form" through 
different gene expression. (more in www.urzeit-code.com/index.php?id=23) The 
optimal result was produced with 75-150v/mm.
