If you want to live on Mars, you're going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they'll encounter off-planet?
Inserting a random DNA mishmash into a plant or bacterium directs it to make a novel protein. Sifting through the resulting molecules, researchers may find ones have medical or agricultural uses.
Plants produce toxic fruit for everything from deterring fungi to causing constipation.
Some leaves are millimetres across, and others are a metre square. An international study has found the essential factors controlling leaf variations.
Bees need pollen to survive and grow, but not all plants can provide the right mix.
Garden pollinators can turn their noses up at the flowers human eyes find most beautiful.
The globe is greening as plants grow faster in response to rising carbon dioxide. But a new analysis shows they aren't using more water to do it - a rare piece of good news for our changing planet.
Health benefits of being close to nature are well established, but the rise of apartment living means we can't always be close to greenery.
A survey of Australians found most (70%) thought that a plant-based diet would prevent disease. But what does the literature say? And is meat really bad that for you?
Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
A seed contains nearly everything a tree needs to get growing. Just add a dash of water, a bit of warmth and the right location, and you'll be seeing green in no time.
Killers, cartoons, and even romantic objects, the cactus's ongoing popularity has led it down some strange paths.
Plants on other planets are bound to be even weirder than the strangest ones we find on Earth – if they even exist.
The fascination and admiration of the natural environment may draw people closer to it, but it's crucial to remain responsible about any desire to own a piece.
A new study appears to show plants can learn from experience and choose a response. This raises some intriguing questions about the possibility of plant cognition.
From spinach that can detect explosives to vegetarian meat, biological technology has the potential to change the world.
Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
Coconut water may be the 'it' drink, but its producers face multiple threats.
We know very little about Australia's most threatened plants.
Every single Cavendish banana plant worldwide is genetically identical. This vast monoculture sets them up for disastrous disease outbreaks. But researchers have ideas on how to protect the crop.
