host plants communicate warning signals through a parasite network, when insects




a team of scientists from the kunming institute of botany in china and the max planck institute for chemical ecology in jena has discovered that parasitic plants of the genus cuscuta (dodder) not only deplete nutrients from their host plants, but also function as important "information brokers" amon...



how plants form their seeds




vegetable, fruit, or grain – the majority of our food results from plant reproduction. researchers at uzh have now discovered the key to how plants regulate pollen growth and seed formation. in addition to seed formation, knowledge about these signaling pathways can be used to influence plant grow...



reductions in individual plant growth sometimes boost community resilience




ann arbor--in sports, sometimes a player has to take one for the team. the same appears to be true in the plant world, where reduced individual growth can benefit the broader community.the findings from the university of michigan's paul glaum and andré kessler of cornell university help explain the...



darpa is engineering plants to act as biohazard sensors




plants naturally react to stimuli and environmental changes. the goal of apt is to control the stimuli that plants respond to and how they react through genetic manipulation. the main idea is that these plants would be self-sustaining, so they would act as monitors for chemicals, pathogens, radiatio...



surprise: transport proteins evolved long before their compounds emerged




as in an arms race plants constantly develop new toxic compounds to protect themselves against herbivores and diseases - and as in war, mobility is important. therefore, plants evolved transport proteins to efficiently and timely concentrate toxic defense compounds where they are needed the most."it...

study ids link between sugar signaling and regulation of oil production in plant




even plants have to live on an energy budget. while they're known for converting solar energy into chemical energy in the form of sugars, plants have sophisticated biochemical mechanisms for regulating how they spend that energy. making oils costs a lot.

the underwater jungles of the sea give clearer water




underwater plants can contribute to a better water quality, shows a new study. the diver marin van regteren is studying the plants chara horrida, stuckenia pectinata, myriophyllum sibiricum and potamogeton perfoliatus. credit: joakim hansenthe new study, that has been conducted in 32 archipelago bay...



plants might have saved earth from permanent ice age




it's plants, its rocks, its microscopic organisms living deep in the sea—it's why most humans get to enjoy glacier-free lifestyles. the post plants might have saved earth from permanent ice age appeared first on wired.

police destroy cannabis plants in crete | news




police said they have destroyed more than 1,500 cannabis plants during an operation in the island of crete.police said a helicopter was used to spot the illegal crop in the area of rethymno.the plants, reaching up to 1 meter in height, were uprooted by officials. there were no reports of arrests.



the parasite that wires plants together




by draining the fluids from several hosts, dodder vines inadvertently allow plants to communicate with each other and share alarm signals.



plants can choose between alternative responses to competition




biologists from the university of tübingen have demonstrated that plants can choose between alternative competitive responses according to the stature and densities of their opponents. a new study by researchers from the institute of evolution and ecology reveals that plants can evaluate the compet...

researchers identify genetic variants that help plants grow in low-iron environm




just like people, plants need iron to grow and stay healthy. but some plants are better at getting this essential nutrient from the soil than others. now, a study led by a researcher at the salk institute has found that variants of a single gene can largely determine a plant's ability to thrive in e...



how plants can tell friend from foe




the plant's immune system can recognize whether a piece of rna is an invader or not based on whether the rna has a threaded bead-like structure at the end, say university of tokyo researchers. their finding provides an answer to the quarter-century-old question of why rnas belonging to the plant esc...



rising carbon dioxide is making the world's plants more water-wise




land plants are absorbing 17% more carbon dioxide from the atmosphere now than 30 years ago, our research published today shows. equally extraordinarily, our study also shows that the vegetation is hardly using any extra water to do it, suggesting that global change is causing the world's plants to ...



plants sacrifice 'daughters' to survive chilly weather




plants adopt different strategies to survive the changing temperatures of their natural environments. this is most evident in temperate regions where forest trees shed their leaves to conserve energy during the cold season. in a new study, a team of plant biologists from the national university of s...

fresh look at desalination plants uncovers bacterial blocks




a new study by a murdoch researcher may help keep desalination plants flowing.

researchers discover how plants respond to changes in light at the molecular lev




plants don't have eyes, but they do "see" their surroundings using light.



how do plants make oxygen? ask cyanobacteria




the ability to generate oxygen through photosynthesis—that helpful service performed by plants and algae, making life possible for humans and animals on earth—evolved just once, roughly 2.3 billion years ago, in certain types of cyanobacteria. this planet-changing biological invention has never ...
