Wood anatomical syndromes vary between shrubs and trees, but no prior work has explicitly evaluated the contingent evolution of wood anatomical diversity in the context of these plant habits. Methods Phylogenetic comparative methods were used to test for contingent evolution of habit, habitat and wood anatomy in the mega-diverse genus Croton (Euphorbiaceae), across the largest and most complete molecular phy- logeny of the genus to date. Key Results Plant habit and habitat are highly correlated, but most wood anatomical features correlate more strongly with habit. -

Chapter 2. Vegetative morphology of plants Vegetative morphology of plants INTRODUCTION: THE PLANT’S BASIC BODY PLAN Most plants are photosynthetic machines: they capture the energy contained in sunlight and transform solar radiation into chemical energy stored the form of bonds in chains of carbon molecules. Through the process of photosynthesis, light and atmospheric CO2 are combined in the leaves of green plants to form simple carbohydrates, which are then used to build other organic molecules such as cellulose, starch, oils, waxes, proteins, or DNA. Six molecules of CO2 (and some 72 photons of light) are needed to form one molecule of glucose: sunlight 6 CO2 + 6 H2O → C6H12O6 + 6 O2 As a byproduct of the process, six molecules of oxygen are formed and dissipated from the leaf tissue into the atmosphere. To achieve this remarkable feat of turning atmospheric carbon dioxide into living molecules while releasing oxygen into the earth’s atmosphere, plants have evolved highly specialized organs. The light-intercepting structure par excellence is the leaf. The set of leaves in the upper aerial part of the plant form the plant’s canopy, where the plant exchanges gases with the atmosphere and intercepts light from the sun. But in order to work its chemical wonder up in the leaves, the plant also needs water and mineral nutrients such as phosphorus, essential for the synthesis of DNA, or nitrogen, essential for manufacturing proteins. In order to obtain these, plants have developed the root —a complex network of underground stem-like organs— whose role is the absorption of water and mineral nutrients from the soil, and, in doing so, anchoring the plant to the ground. -

A VICTORIAN PALM COURT INTRODUCTION Palms comprise a very useful plant family, second only in economic importance to the grasses which supply us with wheat, rice, barley, oats, and other grains. Palms provide the world with food (dates, coconuts, palm oil, hearts of palm), beverages (coconut milk, palm wine), clothing (raincoats, hats), medicines (betel nut), construction materials (thatching, irrigation pipes, logs), rope, fiber, carnauba wax, and hundreds of other products. -
Plant Endophytes Promote Growth and Alleviate Salt Stress in Arabidopsis Thaliana Di Fan, Sowmyalakshmi Subramanian & Donald L
www.nature.com/scientificreports OPEN Plant endophytes promote growth and alleviate salt stress in Arabidopsis thaliana Di Fan, Sowmyalakshmi Subramanian & Donald L. Smith* Plant growth promoting rhizobacteria (PGPR) are a functionally diverse group of microbes having immense potential as biostimulants and stress alleviators. Their exploitation in agro-ecosystems as an eco-friendly and cost-efective alternative to traditional chemical inputs may positively afect agricultural productivity and environmental sustainability. The present study describes selected rhizobacteria, from a range of origins, having plant growth promoting potential under controlled conditions. A total of 98 isolates (ectophytic or endophytic) from various crop and uncultivated plants were screened, out of which four endophytes (n, L, K and Y) from Phalaris arundinacea, Solanum dulcamara, Scorzoneroides autumnalis, and Glycine max, respectively, were selected in vitro for their vegetative growth stimulating efects on Arabidopsis thaliana Col-0 seedlings with regard to leaf surface area and shoot fresh weight. A 16S rRNA gene sequencing analysis of the strains indicated that these isolates belong to the genera Pseudomonas, Bacillus, Mucilaginibacter and Rhizobium. Strains were then further tested for their efects on abiotic stress alleviation under both Petri-plate and pot conditions. Results from Petri-dish assay indicated strains L, K and Y alleviated salt stress in Arabidopsis seedlings, while strains K and Y conferred increases in fresh weight and leaf area under osmotic stress. Results from subsequent in vivo trials indicated all the isolates, especially strains L, K and Y, distinctly increased A. thaliana growth under both normal and high salinity conditions, as compared to control plants. The activity of antioxidant enzymes (ascorbate peroxidase, catalase and peroxidase), proline content and total antioxidative capacity also difered in the inoculated A. -

Understanding the neurobiological mechanisms supporting the relevance of actions mediated by the gut microbiota for brain physiology and neuronal functioning is a key research area. In this review, we discuss the literature showing how the microbiota is emerging as a key regulator of the brain’s function and behavior, as increasing amounts of evidence on the importance of the bidirectional communication between the intestinal bacteria and the brain have accumulated. Based on recent discoveries, we suggest that the interaction between diet and the gut microbiota, which might ultimately affect the brain, represents an unprecedented stimulus for conducting new research that links food and mood. We also review the limited work in the clinical arena to date, and we propose novel approaches for deciphering the gut microbiota–brain axis and, eventually, for manipulating this relationship to boost mental wellness. -
Chamaedorea Elegans1
Fact Sheet FPS-119 October, 1999 Chamaedorea elegans1 Edward F. Gilman2 Introduction This palm, native of the dense rain forests of Mexico and Guatemala, is one of the best indoor Chamaedoreas, tolerating crowded roots and low light levels (Fig. 1). Since lower leaves drop from the plant as it grows, older palms have all their foliage on top of the bright green, shiny stem. It grows five to eight feet tall but is usually kept smaller by pruning the stem back nearly to the ground. Growing very slowly, this pale green, single-stemmed palm is most effective when potted three or more to a container. It can also be an effective accent plant in a ground hugging ground cover in a small scale garden. While excellent when used for a house plant, Parlor Palm can also be used outdoors in a shady understory setting as an accent. The showy stems are bright green. General Information Scientific name: Chamaedorea elegans Pronunciation: kam-ee-DOR-ee-uh EL-uh-ganz Common name(s): Parlor Palm, Neanthebella Family: Arecacea Figure 1. Parlor Palm.
