Anti-Inflammatory Activity of Piper nigrum, Linn and Ricinus communis, Linn.
The severe side effects of steroidal and non-steroidal anti-inflammatory drug evoked the authors to search for new anti-inflammatory drugs from the natural botanical source.

Developmental changes in shoot N dynamics of lucerne (Medicago sativa L.) in relation to leaf growth dynamics as a function of plant density and hierarchical position within the canopy
These data support the idea that leaf growth drives the dynamics of shoot N accumulation.

The plant organelles database (PODB): a collection of visualized plant organelles and protocols for plant organelle research
The plant organelles database was built to promote a comprehensive understanding of organelle dynamics, including organelle function, biogenesis, differentiation, movement and interactions with other organelles.

Whole-Plant Growth Stage Ontology for Angiosperms and Its Application in Plant Biology
Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process.

University Of California, San Diego Biologists Transform Leaves Into Petals
Biologists at the University of California, San Diego have discovered how to genetically convert leaves into petals, an achievement that may be the botanical equivalent of the medieval alchemists' dream of transmuting iron into gold.

Scientists Identify Genes Key To Differentiating Top From Bottom In Plant Leaves
Biologists at the University of Pennsylvania and the University of Wisconsin have identified some of the first genes known to have a hand in differentiating top from bottom in plant leaves

Shared Gene Switch For All Plants Found
A gene-switching mechanism dating back 400 million years to the very first plants that made it onto land has been found by plant biologists at UC Davis.

Unfolding How To Make A Leaf
Whether plants make complex, divided leaves like those of ferns or tomatoes instead of simple, single leaves such as blades of grass is controlled by whether a set of genes, called KNOX1

'Speechless' And 'Mute' Help Break The Silence Of The Leaves
Researchers have discovered two genes that guide land plants to develop microscopic pores that they can open and close as if each pore was a tiny mouth.

Gene Found That Controls Stomatal Cell Growth In Plants
Researchers at Ohio State University have identified the gene that controls the distribution of stomatal cells on leaves, key components for the healthy growth of all plants.

Plant Respiration Not Just An Evolutionary Leftover, Study Shows
A biological process in plants, thought to be useless and even wasteful, has significant benefits and should not be engineered out -- particularly in the face of looming climate change

Gray mold severity and vase life of rose buds after pulsing with citric acid, salicylic acid, calcium sulfate, sucrose and silver thiosulfate
A study was carried out to determine the effect of these substances on the vase life and gray mold severity in rose

Could Improved Wheats Reduce Magnesium Deficiencies?
Newly developed low-phytate breeding lines of wheat have been found to produce flour with 25 percent more magnesium than commercial varieties...

Researchers Pursue Process By Which Oak Trees Contribute To Air Pollution
Trees may not actually commit suicide, but certain species do produce pollutants that hamper their own growth while contributing to global climate changes and causing harm to other life forms...

Ontogenetic differences in mesophyll structure and chlorophyll distribution in Eucalyptus globulus ssp. globulus (Myrtaceae)
The present study measured Ames/A, chlorophyll content, and related structural parameters incrementally throughout the mesophyll of all three, ontogenetic leaf types in E. globulus using light microscopy and image analysis.

Regulation of fruit dehiscence in Arabidopsis
In this review, a summary of our current knowledge is presented, and possible future explorations are suggested.

Stomatal patterning in angiosperms
Stomatal pattern types, means of measuring them, advantages of each type of measurement, and then present patterning from evolutionary, physiological, ecological, and organ views are discussed.

A comparison of three methods for determining the stomatal density of pine needles
A comparison of three methods used to estimate the stomatal density of two species of three-needle pines, Pinus taeda and Pinus ponderosa is reported.

Plants Use "Snorkels" To Survive Floods
When flooded by water, some plants rapidly send up shoots above the surface and use the new leaves as a kind of 'snorkel'.

Plants, Insects Play Cat And Mouse Game
Plants and insects play a far more intricate game than we suspect, says a researcher.
