Genoma do chá descodificado

15 anos depois do genoma da primeira planta ter sido descodificado, chegou a vez da planta do chá:

Citação:
"A team in China has decoded the genetic building blocks of the tea plant, Camellia sinensiswhose leaves are used for all types of tea, including black, green and oolong.
The research gives an insight into the chemicals that give tea its flavour.
Until now, little has been known about the genetics of the plant, despite its huge economic and cultural importance.
(...)
Decoding the genome of the tea plant took more than five years. At three billion DNA base pairs in length, the tea plant genome is more than four times the size of the coffee plant genome and much larger than most sequenced plant species."

Mais de 700 genes podem estar envolvidos na definição da altura

Citando:
"When scientists first read out the human genome 15 years ago, there were high hopes that we'd soon understand how traits like height are inherited. It hasn't been easy. A huge effort to find height-related genes so far only explains a fraction of this trait.
Now scientists say they've made some more headway. And the effort is not just useful for understanding how genes determine height, but how they're involved in driving many other human traits."
