Super Plants with "Microbiome"

I'm gonna share you an article which I read in Science column of a magazine. Here we go!

We are all aware about "Global Warming". Agriculture is affected much because of this. We are in water shortage. Due to Global warming, plants are affected and yield is decreasing all over the world. To overcome this problem, "GM" (Genetically modified) plants were preferred to the "wild" varieties. But the disadvantage of using GM plants is that they take much time to grow or they need more money. Moreover there are "different" opinions with "BT Brinjal". People don't prefer to consume them. Scientists had found a solution to this problem. "Microbiome" is that solution. 

What is Microbiome?

Microbiome is a symbiotic group of Bacteria, Virus and fungi. They have a symbiotic relationship among themselves and also with the plants. 

This Microbiome was first found in the plants surviving extreme conditions of temperature. This Microbiome helps the plants in Deserts to survive in high temperatures and extreme cold conditions. The plants can survive and grow well in high temperatures when they have a symbiotic relationship with these microbiome. They require only less amount of water. 

The microbiome gets it's nutrition from the plants and help them by fixing nitrogen.

Dichanthelium lanuginosum 
The research was done with Dichanthelium lanuginosum . When the fungus in these plants were removed, they were not able to survive extreme conditions. This shows that the fungus was responsible for the heat resistance of the plant. 

When these fungal spores were mixed with wheat seeds and grown, the wheat plants too showed resistance against salt water and low temperatures. They showed increase in height.  

This good yield was because of the "super power" given by the fungus to the plants. Luckily, this fungus showed no toxic effects with plant and the wheat grown by this method is consumable. 

And here after, there is no need to invest much with the GM plants. This is a great news isn't it?

Plant Tissue Culture medium


Today am gonna give certain tips for Plant tissue(PT) culture medium preparation.
The main parameter to be considered in plant tissue culture medium preparation is "Sterility". Your medium has to be very sterile. I could say, when you complete your medium preparation, 75% of your project or experiment is over.

I received a mail questioning the "Alternative for inositol"

Inositol - This is added as a stimulator to the PT medium. This is not a "must" component. But, this in certain plants promote growth.

The essential component for promoting cell growth is Thiamin. It's a vitamin which is basically required for growth of most plants. It is normally used at concentrations ranging from 0.1 to 10.0 mg/liter.

Coconut water, orange juice, malt extracts etc., are also added to PT medium as organic supplements.

You know better alternative for inositol? Then, Comment, share your knowledge :)

Wish you a happy day :)
