Glowing plants spark debate

Glowing plants spark debate | Biosciencia News | Scoop.it
Critics irked over planned release of engineered organism.
Biosciencia's insight:

The Glowing Plant project, which ends its fund-raising campaign on 7 June, seeks to engineer the thale cress Arabidopsis thaliana to emit weak, green-blue light by endowing it with genetic circuitry from fireflies. If the non-commercial project succeeds, thousands of supporters will receive seeds to plant the hardy weed wherever they wish.

How do plants grow toward the light? Scientists explain mechanism behind phototropism

How do plants grow toward the light? Scientists explain mechanism behind phototropism | Biosciencia News | Scoop.it
Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be able to generate energy by photosynthesis.
Biosciencia's insight:

The plant hormone auxin is responsible for a plant's ability to grow towards the light.

Wonderful Things: Desmids, Microscopic Plants of Unusual Beauty and Oddball Behavior

Wonderful Things: Desmids, Microscopic Plants of Unusual Beauty and Oddball Behavior | Biosciencia News | Scoop.it

Biosciencia's insight:

Sometimes I want to show you something just because it’s wonderful. So today I’m introducing a new feature: Wonderful Things. The name is taken from my blog’s masthead, but is also inspired by Howard Carter. When he broke in to the tomb of Tutankhamun, he stuck a candle in the hole and surveyed the contents. After a pause, his patron Lord Carnarvon asked him if he saw anything. “Yes,” Carter replied. “Wonderful things.”

So here’s Wonderful Thing #1: Desmids. I stumbled on these as I was writing about the Alternation of Generations in my post a few back on mosses. With tiny, sculpted bodies and some distinctly unplantlike behavior, desmids are gorgeous botanical oddballs. The best description for them might be “chiseled” — although not the sort of chiseling that comes from protein shakes and 6-minute abs. This is more the kind that comes from guys with Italian last names and lucrative papal commissions.

Take a look!
