In continuation of yesterday’s discussion that Effect of temperature on Life cycle of fruit flies.

Can there be any Natural Variant fruit flies which tolerate low temperature as fruit flies are being trapped from different locations some at high temperature and some at low temperature areas like Delhi and Moradabad…
How do fruit flies or insects survive cold temperature?.

In between the discussion we went and discussed the design what Sachin has in order to prove and disprove that Can fruit flies store Sperms?.

Picture of fruit fly trapped in Moradabad UP…
Aswathy claims that this could be of Drosophila melanogaster as pattern and color of segments at the abdomen is very similar to Drosophila melanogaster.

But what are the diagnostic feature to identify this fly as Drosophila melanogaster?.

Batul quoted a reference which says Rhythm can also be seen in fruit flies egg laying behaviour…

Egg laying is Rhythmic

Extensive research has been carried out to understand how circadian clocks regulate various physiological processes in organ-isms. The discovery of clock genes and the molecular clockwork has helped researchers to understand the possible role ofthese genes in regulating various metabolic processes. InDrosophila melanogaster, many studies have shown that the basicarchitecture of circadian clocks is multi-oscillatory…

I would also like to quote another line from the same reference which says
Unlike most other circadian rhythms, the egg-laying rhythm is rhythmic under constant light conditions, andthe endogenous or free-running period of the rhythm is greater than those of most other rhythms.

Very interesting thing has come up
That we have been discussing about the Nobel Prize winning work in understanding the Molecular mechanism of Circadian rhythm…

Similarly each cell should be having per and tim gene and there are some cells which are regulating sleep wake cycle and per and tim gene should also be there in Heart cells to regulate hear beat as heart beat is also a Rhythm and similarly in other cells like hepar cells…

We had also discussed about Mutants and how Mutants are different from Natural Variant…

The fruit flies that i have got yesterday (Moradabad temp. Max-20’ and min-6’) could be a Natural Variant which is cold tolerance…

The discussion went deep and enabled us to understand how per and tim genes work and regulate sleep wake cycle.

A movie was also presented in order to understand the same.

Mango Fruiting is also a cycle, is there any similarity or Rhythm in mango fruiting or sleep wake cycle in fruit flies.

Circadian Vs Circannual Rhythm
