An Evaluation of Oral Subchronic Toxicity of Maizinol (UP165), a Zea mays Leaf Extract

Journal of Applied Toxicology, EarlyView.
ABSTRACT Maize (Zea mays) has been consumed by humans for millennia and represents the third most abundant crop grown globally. Maize and maize‐derived products have a long history of safe consumption from bread and other cereal products in human diets worldwide. Aside from key dietary components like carbohydrates and proteins, the corn plant contains

Silicon and Mechanisms of Plant Resistance to Insect Pests

Plants, 2018
This paper reviews the most recent progress in exploring silicon-mediated resistance to herbivorous insects and the mechanisms involved. The aim is to determine whether any mechanism seems more common than the others as well as whether the mechanisms are

Terniopsis chanthaburiensis (Podostemaceae), a new record for China and its complete plastid genome

Nordic Journal of Botany, EarlyView.
The genus Terniopsis consists of plants that have not been thoroughly studied, with many species remaining taxonomically unresolved. In this study, Terniopsis chanthaburiensis is reported as a new record of China based on morphological traits. Then, we assembled and annotated its chloroplast genome based on genome skimming data.

Stem anatomy and ontogeny of vascular variants in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

Nordic Journal of Botany, EarlyView.
An increase in stem thickness and ontogeny of successive cambia, intraxylary cambium, and inter‐and intraxylary phloem is elaborated for the first time in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae). As the plants grew older, several small segments of cambium were initiated simultaneously external to the phloem formed by regular ...

Phylogenetic footprint of the plant clock system in angiosperms: evolutionary processes of Pseudo-Response Regulators

BMC Evolutionary Biology, 2010
Background Plant circadian clocks regulate many photoperiodic and diurnal responses that are conserved among plant species. The plant circadian clock system has been uncovered in the model plant, Arabidopsis thaliana, using genetics and systems biology ...

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

PLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

The Core Eudicot Boom Registered in Myanmar Amber [PDF]

Scientific Reports, 2018
AbstractA perfect flower in a mid-Cretaceous (early Cenomanian) Myanmar amber is described as Lijinganthus revoluta gen. et sp. nov. The fossil flower is actinomorphic and pentamerous, including calyx, corolla, stamens, and gynoecium. The sepals are tiny, while the petals are large and revolute.
