Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

open access: yesAllergy, EarlyView.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,

GeARF5/GeIAA33‐GeSWEET14 module balances the secondary metabolic biosynthesis to increase the yield and quality in Gastrodia elata

open access: yesJournal of Integrative Plant Biology, EarlyView.
Auxin signaling regulates the formation of vegetative propagation corms in Gastrodia elata by regulating sugar‐acid interconversion, which in turn regulates polysaccharide and starch biosynthesis as well as biosynthesis of the bioactive metabolite gastrodin.

n vitro pollen quantity, viability and germination tests in quince

open access: yesAFRICAN JOURNAL OF BIOTECHNOLOGY, 2011
Quince (Cydonia oblonga Mill.) cvs. Ekmek, Esme, Limon, Ege 2, Ege 22, Ege 25 and Quince-A rootstock pollens were collected in April from the unopened pink balloon-stage flowers on mature trees. The pollen amount was between 20063 pollen/flower (‘Ege 25’) and 11906 pollen/flower (‘Limon’) with hemacytometer. The lowest and highest pollen viability were

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

open access: yes, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

OsFKBP20‐1b stabilizes OsUPF1 and OsUPF2 to promote the degradation of aberrant mRNAs during dehydration stress

open access: yesJournal of Integrative Plant Biology, EarlyView.
The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.
