Rapid evolution of morphology and adaptive life history in the invasive California wild radish (Raphanus sativus) and the implications for management. [PDF]

open access: yes, 2009
Understanding the evolution and demography of invasive populations may be key for successful management. In this study, we test whether or not populations of the non-native, hybrid-derived California wild radish have regionally adapted to divergent ...

RNA Levels and Activity of \u3cem\u3eFLOWERING LOCUS C\u3c/em\u3e are Modified in Mixed Genetic Backgrounds of \u3cem\u3eArabidopsis Thaliana\u3c/em\u3e [PDF]

open access: yes, 2001
Flowering time and FLOWERING LOCUS C (FLC) RNA levels were analyzed in different accessions of Arabidopsis thaliana and in mixed genetic backgrounds resulting from crosses between accessions.

Co-targeting RNA Polymerases IV and V Promotes Efficient De Novo DNA Methylation in Arabidopsis. [PDF]

open access: yes, 2019
The RNA-directed DNA methylation (RdDM) pathway in plants controls gene expression via cytosine DNA methylation. The ability to manipulate RdDM would shed light on the mechanisms and applications of DNA methylation to control gene expression.

Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]

open access: yes, 2013
We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in

Flowering time: From photoperiodism to florigen [PDF]

open access: yesCurrent Biology, 1998
An Arabidopsis blue-light receptor, Cry2, has been found to play a critical role in the photoperiodic control of flowering time; and genes have been identified that may control the production of a transmissible flower-inducing signal, which may turn out to be the long-elusive putative flowering hormone 'florigen'.

All roads lead to Rome: QTL analysis for vernalization requirement and dissection of allelic variation uncovered unexpected diversity of FLC loci in Camelina sativa

open access: yesFrontiers in Plant Science
Winter camelina (Camelina sativa) is a climate-resilient oilseed crop that has received attention as a feedstock crop for advanced, low-carbon-intensity biofuels. Breeding programs working on winter camelina improvement have to contend with heterogeneous

Influence of cllimate warmening on flowering time of early and lately flowering forest plants

open access: yesRUDN Journal of Ecology and Life Safety, 2011
It is popular to lean upon the bioclimatic models while discussing global warming influence on land and water ecosystems. These models to some extend assume similarity of phenological reaction of organisms on air temperature rising.

Association mapping of flowering time QTLs and insight into their contributions to rapeseed growth habits

open access: yesFrontiers in Plant Science, 2016
Plants have developed sophisticated systems to adapt to local conditions during evolution, domestication and natural or artificial selection. The selective pressures of these different growing conditions have caused significant genomic divergence within ...

Escape from floral herbivory by early flowering in Arabidopsis halleri subsp. gemmifera [PDF]

open access: yes, 2018
Natural selection on flowering phenology has been studied primarily in terms of plant-pollinator interactions and effects of abiotic conditions. Little is known, however, about geographic variation in other biotic factors such as herbivores and its ...
