Integrative Study Supports the Role of Trehalose in Carbon Transfer From Fungi to Mycotrophic Orchid
Publikováno v:
Frontiers in Plant Science, Vol 12 (2021)
Orchids rely on mycorrhizal symbiosis, especially in the stage of mycoheterotrophic protocorms, which depend on carbon and energy supply from fungi. The transfer of carbon from fungi to orchids is well-documented, but the identity of compounds ensuri

Orchid protocorms are completely mycoheterotrophic structures. Although saccharides are proposed as the main energy and carbon (C) sources provided by fungi, there is only limited knowledge on their effects. For the first time, utilization of a wide

Arsenic (As) contaminates the food chain and decreases agricultural production through impairing plants, particularly due to oxidative stress. To better understand the As tolerance mechanisms, two contrasting tobacco genotypes: As-sensitive Nicotiana

We describe a method for growing orchids of the genera Dactylorhiza and Ophrys, two European members of the subfamily Orchidoideae, from seeds to mature plants using asymbiotic in vitro cultures and glasshouse pot cultures. Four media were used: two

Versatile roles of sorbitol in higher plants: luxury resource, effective defender or something else?
Publikováno v:
Planta. 256
Sorbitol metabolism plays multiple roles in many plants, including energy and carbon enrichment, effective defence against various stresses and other emerging specific roles. The underlying mechanisms are, however, incompletely understood. This revie

The potential contamination of the food chain is the most important aspect of arsenic (As) pollution, since it is highly toxic to all organisms. Thus, the search for As hyperaccumulators suitable to remove As from contaminated soils appears to be a v

WEE1 regulates the cell cycle by inactivating cyclin dependent protein kinases (CDKs) via phosphorylation. In yeast and animal cells, CDC25 phosphatase dephosphorylates the CDK releasing cells into mitosis, but in plants, its role is less clear. Expr

Rate of photosynthesis and related plant carbohydrate status are crucial factors affecting plant vigor. Sugars providing carbon and energy sources serve also as important signaling molecules governing plant growth and development through a complex re
