Photophysiological and photosynthetic complex changes during iron starvation in Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942

open access: yes, 2013
Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

Synergistic benefits of agrivoltaics for grape production and solar energy efficiency in a Mediterranean vineyard

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Grapevine production is increasingly challenged by global warming, with global wine output falling to a six‐decade low in 2024. At the same time, the vine and wine sector faces growing pressure to reduce its carbon footprint. Agrivoltaics, which integrates solar photovoltaic (PV) modules into plant production systems, offers a potential pathway to ...

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.

Precision agriculture for water saving: The case of processing tomato and table grape

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Agriculture faces increasing pressure to produce high‐quality food while reducing water use under intensifying climate change and water scarcity. This study compared sensor‐based precision irrigation, drone monitoring, and near‐infrared spectroscopy with conventional farmer management in table grape and processing tomato production systems.
