Communication between source organs (exporters of photoassimilates) and sink organs
(importers of fixed carbon) has a pivotal role in carbohydrate assimilation and partitioning …

Highlights•Autophagy is essential for nutrient recycling and remobilization in plants.•Both
bulk and specific autophagy participate to nutrient recycling.•Autophagy defects result in …

In plants, iron (Fe) transport and homeostasis are highly regulated processes. Fe deficiency
or excess dramatically limits plant and algal productivity. Interestingly, complex and …

In eukaryotes, autophagy helps maintain cellular homeostasis by degrading and recycling
cytoplasmic materials via a tightly regulated pathway. Over the past few decades, significant …

Bread wheat (Triticum aestivum L.) is cultivated on more land than any other crop and
produces a fifth of the calories consumed by humans. Wheat endosperm is rich in starch yet …

Human mineral malnutrition or hidden hunger is considered a global challenge, affecting a
large proportion of the world's population. The reduction in the mineral content of edible …

Iron (Fe) is an essential plant micronutrient since many cellular processes including
photosynthesis, respiration, and the scavenging of reactive oxygen species depend on …

Zinc biofortification in rice can be improved by altering Zn application timing and placement
and cultivar choice. We made a comprehensive assessment on this, analysing Zn, Fe and …

Chloroplasts originated about three billion years ago by endosymbiosis of an ancestor of
today's cyanobacteria with a mitochondria-containing host cell. During evolution …

Leaf senescence is a complex mechanism controlled by multiple genetic and environmental
variables. Different crops present a delay in leaf senescence with an important impact on …
