Genome Editing Technologies to Improve Health‐Related Phytocompounds in Crops

Food Frontiers, EarlyView.
ABSTRACT Due to rapid global population growth and the resulting significant increase in food demand, the world is facing an epidemic of malnutrition. Although yield improvement remains one of the main targets of breeding programs, much attention is being paid to the nutritional aspects of crops, including nutrients and bioactive compounds that are ...

Nuclear Photosynthetic Gene Expression Is Synergistically Modulated by Rates of Protein Synthesis in Chloroplasts and Mitochondria [PDF]

, 2006
Arabidopsis thaliana mutants prors1-1 and -2 were identified on the basis of a decrease in effective photosystem II quantum yield. Mutations were localized to the 5'-untranslated region of the nuclear gene PROLYL-tRNA SYNTHETASE1 (PRORS1), which acts in ...

Springtime upwelling conditions influence microbial communities and dissolved thiamin compounds in the California Current Ecosystem

Limnology and Oceanography, EarlyView.
Abstract Understanding dissolved concentrations of the essential coenzyme thiamin (vitamin B1) can provide insights into the biological controls on highly productive upwelling systems such as the California Current Ecosystem. To connect thiamin availability with microbial communities in the California Current Ecosystem, we measured concentrations of ...

The activity of NADH-, NADPH- and Fd-dependent glutamate synthase in the plastids and cytosol of Pisum arvense L. root cells

Acta Societatis Botanicorum Poloniae, 2014
Three forms of glutamate synthase (NADH-GOGAT, NADPH-GOGAT and Fd-(ferredoxin) GOGAT) were found in the plastids and cytosol of Pisum arvense root cells.

Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

Limnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Nectar and oleiferous trichomes as floral attractants in Bulbophyllum saltatorium Lindl. (Orchidaceae) [PDF]

, 2017
Although many Orchidaceae have deceit flowers that produce no reward, the most common reward, when present, is nectar. Bulbophyllum, however, is unusual in that the labellar secretions of most species investigated to date lack sugars, and, therefore ...

Eco‐Friendly Synthesis of Selenium Nanoparticles via Sternbergia candida: Enhancing Antioxidant Defense and Mitigating Salt Stress in Pepper (Capsicum annuum L.) Plants

ChemistryOpen, EarlyView.
Sternbergia candida serves as a flexible reducing agent for the synthesis of SeNPs utilizing an economical and ecologically safe extract. Applications of selenium have demonstrated that plants cultivated in salinity preserve proper osmotic conditions and minimize cellular damage, as evidenced by photosynthetic pigments, proline, and MDA data.

Nectar defense and hydrogen peroxide in floral nectar of Cucurbita pepo

Acta Agrobotanica, 2015
This study was carried out to investigate some similarities between the nectaries of Nicotiana sp. and Cucurbita pepo, such as starch accumulation in the nectary parenchyma, changes in nectary color during maturation, and the production of a large ...

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

PLANTS, PEOPLE, PLANET, EarlyView.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...
