Dear Editor, Plant cell suspension cultures have been used as model systems to circumvent the problems associated with the analyses of a multi-factorial plant that is composed of multiple tissue and cell types exposed to diverse signals. A number of plant suspension cultures have proven to be valuable to study various topics including defense response, secondary metabolite formation, ion transport, gene regulation, and signal duction （Roitsch and sinha, 2002 and references therein）. However, most cultures reported to date, including the cultures from model species such as Arabidopsis （Christie and Jenkins,

Stephen Hawking gave a formula for the temperature of black holes as given by . Some of the black holes have their spinning velocity from 50% to 99% of the velocity of light. Due to this velocity, the mass of black holes will vary which cause the variation in the temperature of black holes. In the present research article, we have applied the variation of mass with velocity to obtain the rate of change in temperature of the black holes with respect to velocity. We have also calculated their values for super dense stars like black holes existing in XRBs and AGN and concluded that for super dense stars like black holes of lower velocity as well as the velocity comparable to the velocity of light, the rate of change in temperature with respect to velocity is directly proportional to their velocities. This work will help us to find out the variation in temperature of different black holes spinning with different velocity percentage related to light speed and can be used as the references for other research works.
