Auxin and Gibberellin signaling cross-talk promotes hypocotyl xylem expansion and cambium homeostasis.

Journal of Experimental Botany, 2021
During secondary growth, the thickening of plant organs, wood (xylem) and bast (phloem) are continuously produced by the vascular cambium. In Arabidopsis hypocotyl and root, we can distinguish two phases of secondary growth based on cell morphology and ...

Positive pressure in xylem and its role in hydraulic function.

New Phytologist, 2020
Although transpiration-driven transport of xylem sap is well known to operate under absolute negative pressure, many terrestrial, vascular plants show positive xylem pressure above atmospheric pressure on a seasonal or daily basis, or during early ...

Tradeoff between storage capacity and embolism resistance in the xylem of temperate broadleaf tree species.

Tree Physiology, 2020
Xylem traits are critical plant functional traits associated with water transport, mechanical support, and carbohydrate and water storage. Studies on the xylem hydraulic safety-efficiency tradeoff are numerous; however, the storage function of xylem ...

Functional Status of Xylem Through Time.

Annual Review of Plant Biology, 2019
Water transport in vascular plants represents a critical component of terrestrial water cycles and supplies the water needed for the exchange of CO2 in the atmosphere for photosynthesis.

How Ralstonia solanacearum Exploits and Thrives in the Flowing Plant Xylem Environment.

Trends in Microbiology, 2018
The plant wilt pathogen Ralstonia solanacearum thrives in the water-transporting xylem vessels of its host plants. Xylem is a relatively nutrient-poor, high-flow environment but R.
