Botany student shows 'New England Banksia' a distinct species The New England Banksia is largely restricted to the eastern edge of the New England Tableland, and is common in places along Waterfall Way. Ms Stimpson's research has raised this flowering plant, until now classified as a variety of the Hairpin Banksia (B. spinulosa), to the taxonomic level of a distinct species. The study was published in the open access journal PhytoKeys

Peaches, Beautiful And Fleeting, Thanks To Fuzzy Thin Skin A summer peach is a seasonal treat, but why are they so hard to find for the rest of the year? As it turns out, that fuzzy, thin skin might be partially to blame for the fruit's finicky reputation.

Ethylene of no effect -- why peppers do not mature after picking Tomato breeders scored a coup several years ago when they identified tomatoes with a genetic defect that made the fruits mature very slowly, even under the influence of the phytohormone ethylene.

Lace plants explain programmed cell death Programmed cell death (PCD) is a highly regulated process that occurs in all animals and plants as part of normal development and in response to the environment. New research published in BioMed Central's open access journal BMC Plant Biology is the first to document the physiological events in the lace plant (Aponogeton madagascariensis) which occur via PCD to produce the characteri

Hitting back at 'wiretapping' parasite Dodder vines are parasitic plants that suck water, nutrients and information from other plants as they spread over them. Plant biologists at the University of California, Davis, have now shown that they can make plants resistant to dodder by attacking the junctions where the parasite taps into the host.

Lighting up the plant hormone 'command system' Light is not only the source of a plant's energy, but also an environmental signal that instructs the growth behavior of plants. As a result, a plant's sensitivity to light is of great interest to scientists and their research on this issue could help improve crop yields down the road. Similarly understanding a plant's temperature sensitivity could also help improve agriculture and f
Researchers discover cannabis 'pharma factory' U of S researchers have discovered the chemical pathway that Cannabis sativa uses to create bioactive compounds called cannabinoids, paving the way for the development of marijuana varieties to produce pharmaceuticals or cannabinoid-free industrial hemp. The research appears online in the July 16 early edition of the Proceedings of the National Academy of Sciences (PNAS).

Engineers convert a natural plant protein into drug-delivery vehicles Finding biocompatible carriers that can get drugs to their targets in the body involves significant challenges. Beyond practical concerns of manufacturing and loading these vehicles, the carriers must work effectively with the drug and be safe to consume. Vesicles, hollow capsules shaped like double-walled bubbles, are ideal candidates, as the body naturally produces similar struct

Want bigger plants? Get to the root of the matter Plant scientists have imaged and analyzed, for the first time, how a potted plant's roots are arranged in the soil as the plant develops. In this study, to be presented at the Society for Experimental Biology meeting on 30th June, the team has also found that doubling plant pot size makes plants grow over 40% larger.

Is your leaf left-handed? The front of a leaf is different from the back of a leaf and the tip is different from the base. However, a leaf from a tomato or an Arabidopsis plant superficially appears to be bilaterally symmetrical, or the same on the left and right sides. Don't let its appearance fool you; there is an underlying asymmetry between the left and right sides of such leaves—it just took a while for scienti

Carbon is key for getting algae to pump out more oil Overturning two long-held misconceptions about oil production in algae, scientists at the U.S. Department of Energy's Brookhaven National Laboratory show that ramping up the microbes' overall metabolism by feeding them more carbon increases oil production as the organisms continue to grow. The findings — published online in the journal Plant and Cell Physiology on May 28, 2012

Herbivores select on floral architecture in a South African bird-pollinated plant Floral displays, such as the color, shape, size, and arrangement of flowers, are typically thought to have evolved primarily in response to selection by pollinators—for animal-pollinated species, being able to attract animal vectors is vital to an individual plant's reproductive success. But can herbivores also exert similarly strong selective forces on floral characters? New research on two siste

How plants make cocaine Humans encounter alkaloids every day, they constitute a very large group of natural nitrogen-containing compounds with diverse effects on the human organism. A large variety of plant-produced alkaloids have strong pharmacological effects, and are used as toxins, stimulants, pharmaceuticals or recreational drugs, including caffeine, nicotine, morphine, quinine, strychnine, atropine and cocaine.

How plants chill out Although scientists have made significant advances in understanding how plants elongate at high temperature, little is known of the physiological consequences of this response. To investigate these consequences, the researchers, led by Dr Kerry Franklin and Professor Alistair Hetherington in Bristol's School of Biological Sciences, studied thale cress (Arabidopsis thaliana), a small flower

Plant growth without light control Plants are dependent on the sun. Sunlight does not only supply them with energy, but also controls their development steps. So-called photoreceptors activate the processes of germination, leaf development, bud formation, and blossoming in the cells. The light-absorbing component of a photoreceptor may be replaced by a chemically similar synthetic substance. For the first time, the effects on compl

Researchers find mechanism that gives plants 'balance' When a plant goes into defense mode in order to protect itself against harsh weather or disease, that's good for the plant, but bad for the farmer growing the plant. Bad because when a plant acts to defend itself, it turns off its growth mechanism.
