Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Developing know-how for the improvement and sustainable management of teak genetic resources [PDF]

, 2008
The project had the following objectives: To trace and quantify genetic diversity of teak within its natural range, DNA markers were used to assay the current distribution of genetic diversity within and between populations, investigate its mating ...

A simple and affordable protocol to assess censer seed dispersal: First confirmation of the mechanism in the genus Solanum

Applications in Plant Sciences, EarlyView.
Abstract Premise The censer seed dispersal mechanism, whereby mature fruits are retained on plants and seeds dispersed by mechanical shaking, is among the most specialized wind‐aided seed dispersal strategies employed by the flowering plants. An efficient, affordable, and easily repeatable protocol for determining whether a species uses this unusual ...

Relationship between botanical origin and antioxidants vitamins of bee-collected pollen

Química Nova, 2009
This study quantified vitamin C, E and β-carotene in samples of fresh bee-collected pollen and correlating them with the botanical origin. Vitamin content varied between 13.5 and 42.5 µg/g for vitamin E; 56.3 and 198.9 µg/g for β-carotene and ...

MicroR159 regulation of most conserved targets in Arabidopsis has negligible phenotypic effects [PDF]

, 2016
BACKGROUND A current challenge of microRNA (miRNA) research is the identification of biologically relevant miRNA:target gene relationships. In plants, high miRNA:target gene complementarity has enabled accurate target predictions, and slicing of target ...

THE PALYNOLOGY CONTRIBUTION IN PALAEOENVIRONMENT INVESTIGATION. A CASE-STUDY OF A LATEGLACIAL-HOLOCENE SEDIMENTARY SEQUENCE NEAR BOLOGNA (NORTHERN ITALY)

EQA, 2017
The palynological studies are extremely relevant in the investigation of the evolution of palaeoenvironments. A case of pedopalynological studies was applied to the Lateglacial to Holocene sedimentary sequence derived from a small site located in San ...

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

, 2018
Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.
