Transcriptome analysis reveals novel enzymes for apo-carotenoid biosynthesis in saffron and allows construction for crocetin synthesis in yeast.

Journal of Experimental Botany, 2019
Crocus sativus is generally considered the source of saffron spice and rich in apo-carotenoid compounds such as crocins, crocetin, picrocrocin and safranal, which possess effective pharmacological activities.

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, EarlyView.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Water status and associated processes mark critical stages in pollen development and functioning.

Annals of Botany, 2012
BACKGROUND The male gametophyte developmental programme can be divided into five phases which differ in relation to the environment and pollen hydration state: (1) pollen develops inside the anther immersed in locular fluid, which conveys substances from

Natural selection on plant resistance to herbivores in the native and introduced range [PDF]

, 2015
. When plants are introduced into new regions, the absence of their co-evolved natural enemies can result in lower levels of attack. As a consequence of this reduction in enemy pressure, plant performance may increase and selection for resistance to ...

Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

Journal of Ecology, EarlyView.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species

Plant Species Biology, EarlyView.
We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

The characterization of transgenic tomato overexpressing gibberellin 20-oxidase reveals induction of parthenocarpic fruit growth, higher yield, and alteration of the gibberellin biosynthetic pathway.

Journal of Experimental Botany, 2012
Fruit-set and growth in tomato depend on the action of gibberellins (GAs). To evaluate the role of the GA biosynthetic enzyme GA 20-oxidase (GA20ox) in that process, the citrus gene CcGA20ox1 was overexpressed in tomato (Solanum lycopersicum L.) cv Micro-

Phenology of Richeria grandis Vahl: A dioecious species with wide geographical distribution and unique environmental specificity

Plant Species Biology, EarlyView.
Richeria grandis exhibits synchronized and highly seasonal reproductive phenology, emphasizing its strong dependence on local climate dynamics. The species' supra‐annual fruit production and evergreen vegetative habit highlight adaptive strategies for resource utilization and ecosystem balance.
