Conifers Phytochemicals: A Valuable Forest with Therapeutic Potential

open access: yesMolecules, 2021
Conifers have long been recognized for their therapeutic potential in different disorders. Alkaloids, terpenes and polyphenols are the most abundant naturally occurring phytochemicals in these plants.

In Vitro Plant Regeneration in Conifers: The Role of WOX and KNOX Gene Families

open access: yesGenes, 2021
Conifers are a group of woody plants with an enormous economic and ecological importance. Breeding programs are necessary to select superior varieties for planting, but they have many limitations due to the biological characteristics of conifers. Somatic

Photoperiod and temperature as dominant environmental drivers triggering secondary growth resumption in Northern Hemisphere conifers

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Forest trees can live for hundreds to thousands of years, and they play a critical role in mitigating global warming by fixing approximately 15% of anthropogenic CO2 emissions annually by wood formation.

Champions of Winter Survival: Cold acclimation and Molecular Regulation of Cold Hardiness in Evergreen Conifers.

open access: yesNew Phytologist, 2020
Evergreen conifers are champions of winter survival, based on their remarkable ability to acclimate to cold and develop cold-hardiness. Counterintuitively, autumn cold acclimation is triggered not only by exposure to low temperature, but also by a ...

The rise of angiosperms pushed conifers to decline during global cooling

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Competition for common resources can make some species groups thrive and others decline. Flowering plants rose to dominance between 125 and 80 Ma, undergoing an explosive radiation that is believed to have impacted long-established plant ...

Two dominant boreal conifers use contrasting mechanisms to reactivate photosynthesis in the spring

open access: yesNature Communications, 2020
Boreal forests are dominated by evergreen conifers that show strongly regulated seasonal photosynthetic activity. Understanding the mechanisms behind seasonal modulation of photosynthesis is crucial for predicting how these forests will respond to ...

An arrangement of secretory cells involved in the formation and storage of resin in tracheid-based secondary xylem of arborescent plants

open access: yesFrontiers in Plant Science, 2023
The evolution of the vascular system has led to the formation of conducting and supporting elements and those that are involved in the mechanisms of storage and defense against the influence of biotic and abiotic factors.

Mature conifers assimilate nitrate as efficiently as ammonium from soils in four forest plantations.

open access: yesNew Phytologist, 2020
Conifers are considered to prefer to take up ammonium over nitrate. However, this conclusion is mainly based on hydroponic experiments that separate roots from soils.

Enzymes Involved in the Biosynthesis of Arginine from Ornithine in Maritime Pine (Pinus pinaster Ait.)

open access: yesPlants, 2020
The amino acids arginine and ornithine are the precursors of a wide range of nitrogenous compounds in all living organisms. The metabolic conversion of ornithine into arginine is catalyzed by the sequential activities of the enzymes ornithine ...
