Filipino scientist discovers rice's ancient origins

Using large-scale gene re-sequencing, Purugganan and a team of researchers traced the origins of domesticated rice as far back as 9,000 years ago to China's Yangtze Valley, according to a May 2 press release from New York University.

The tens of thousands of kinds of rice available in the world today are mostly varieties of either japonica or indica, the two major subspecies of Asian rice, Oryza sativa.

It had been a subject of scientific debate whether these two subspecies had a common origin, or developed separately in China and India.

"The multiple-origin model has gained currency in recent years as biologists have observed significant genetic differences between indica and japonica, and several studies examining the evolutionary relationships among rice varieties supported more than domestication in both India and China," the release said.

However, Purugganan's team weighed in favor of a single origin because computer-based genetic analysis showed that the two subspecies are more closely related to each other than they are to any wild rice species in either India or China.

I had some good rice last night with a bell pepper stuffed with ground meat.

[SunkenCiv]

Mmmm, good. :’)

If you were here in the Philippines, you would be having rice
at least three times per day, every day.
A rice cooker is a standard in every kitchen.

[SunkenCiv]

That would be going against the grain.

So cousin cannabis sativa is perhaps not so unhealthful ?

Just askin'

I had some good rice last night with a bell pepper stuffed with ground meat.

What a coincidence! Last night, I served chili rellenos, made with Anaheims that had some bell pepper and chopped beef in the cheese stuffing; and Mexican rice on the side.

Alas: I can grow wheat, rye, barley, and corn, but not rice: not enough water nor gumption.

The key word in this report is “Domestication”. Just about Everything we eat has been Domesticated. The question is “who did the Domesticating”?. Evolution on its own only produces things that are wild and “UN-Domesticated”.

Hey -
Surprisingly enough, one of the best books, IMO, written about the Viet Nam war was written by a US AID man whose job was helping the locals grow rice. He worked closely with the worlds premier rice authority, which was/is in the Philippines. The book was about his doing his job ion the face of the VC political cadre terrorizing the farmers for co-operating and the U.S. troops coming to fight the war. They were stuck in the middle.
I have the book somewhere on my shelves;unfortunately I cannot remember the exact name of it.
I'm a VN Vet and went through a period, during the late '70s and through the '80s of getting and reading every book I could find about Viet Nam.
Also, some of the best rice in the world is grown in Texas, U.S.A.

Ever Onward!

Does it have DNA residue from jon carry’s thigh?

“And they won’t put anything into that cooker except that damned expensive Jasmine rice from Thailand”

I don’t know about that.
We buy a kilo of “Ivory” for less the $1.00
It is one of a dozen types.
I have not even asked for any rice from Thailand, but I will ask about it tomorrow.

I don’t think I’d heard of it before, but it sounds interesting.

Jasmine rice smells wonderful!
