Ancient flowering plants: DNA sequences and angiosperm classification

Combined with complete genomic sequences, these data will vastly improve understanding of the genetic basis of plant diversity.

Infra-specific folk taxonomy in sorghum (Sorghum bicolor (L.) Moench) in Ethiopia: folk nomenclature, classification, and criteria

The study aims to characterise folk taxonomy: classification, naming, criteria, to identify the folk species, subspecies and varieties in the region, and to assess the consistency in folk taxonomy and compare it with formal taxonomy.

The importance of chemosensory clues in Aguaruna tree classification and identification

This paper will describe the importance of odor for woody plant taxonomy and identification among the Aguaruna Jívaro of the northern Peruvian Amazon, focusing on the Aguaruna category númi (trees excluding palms).

Desert Plant May Hold Key To Surviving Food Shortage

The plant, Kalanchoe fedtschenkoi, is unique because, unlike normal plants, it captures most of its carbon dioxide at night when the air is cooler and more humid

Cotton Studies Target Killer: Fusarium Wilt

The long, warm days of a typical California summer make life easy for sun-loving cotton plants.

Native Plants Can Also Benefit From The Invasive Ones

Using empirical tests, a pioneering study shows how plant species, such as the prickly pear, invade Mediterranean ecosystems

Significant Increase In Alien Plants In Europe Observed

The number of alien plant species has more than tripled over the last 25 years.

Student Proves Giant Whorled Sunflower's Extreme Rarity

For several months last spring, the Vanderbilt greenhouse held more individual plants of a rare species of native sunflower than are known to exist in the wild.

Genetic Differences In Clover Make One Type Toxic

Some clovers have evolved genes that help the plant produce cyanide -- to protect itself against little herbivores, such as snails, slugs and voles, that eat clover.

World's Hottest Chile Pepper Discovered

Researchers at New Mexico State University recently discovered the world's hottest chile pepper.

Pictures of unspecified plant species

Pictures were taken at the Eastern part of Nepal

PlantTribes: a gene and gene family resource for comparative genomics in plants

The PlantTribes database is a plant gene family database based on the inferred proteomes of five sequenced plant species

Use of DNA barcodes to identify flowering plants

Methods for identifying species by using short orthologous DNA sequences, known as "DNA barcodes," have been proposed and initiated to facilitate biodiversity studies, identify juveniles, associate sexes, and enhance forensic analyses.

Chemical Constituents of Dichloromethane Extract of Cultivated Satureja khuzistanica

Four compounds ß-sitosterol, ß-sitosterol-3-O-ß-D-glucopyranoside, ursolic acid and 4',5,6-trihydroxy-3', 7-dimethoxyflavone were characterized from the dichloromethane extract of the aerial parts of Satureja khuzistanica (Lamiaceae)

Plastid genome structure and loss of photosynthetic ability in the parasitic genus Cuscuta

The genus Cuscuta (dodder) is composed of parasitic plants, some species of which appear to be losing the ability to photosynthesize.

Rapid decay of tree-community composition in Amazonian forest fragments

The authors show that forest fragmentation provokes surprisingly rapid and profound alterations in Amazonian tree-community composition.

Model analysis of flowering phenology in recombinant inbred lines of barley

A generic model for flowering phenology as a function of daily temperature and photoperiod was applied to predict differences of flowering times among 96 individuals (including the two parents) of a recombinant inbred line population in barley

Preserving Genetic Diversity Of Popular GeraniumPreserving Genetic Diversity Of Popular Geranium

Researchers at The Ohio State University have demonstrated that Target Region Amplification Polymorphism, or TRAP, is an effective method for preserving the important genetic diversity of ornamental flower collections.
