Transport of Amino Acids via Xylem and Phloem in Detached Wheat Shoots

open access: yes, 1991
In maturing wheat ears the xylem predominantly feeds the glumes, while the phloem is directed to the developing grains. A transfer of amino acids and rubidium from the xylem lo the phloem was observed in the peduncle.

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

open access: yesAgricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Organic and inorganic sulfur transport in the xylem sap and the sulfur budget of Picea abies trees

open access: yes, 1998
Temporal changes in inorganic and organic sulfur compounds (sulfate, glutathione, cysteine, methionine) were analyzed in xylem sap of 40-year-old Norway spruce (Picea abies (L.) Karst.) trees growing on acidic soils at a healthy and a declining stand in ...

The AAP gene family for amino acid permeases contributes to development of the cyst nematode Heterodera schachtii in roots of Arabidopsis [PDF]

open access: yes, 2013
The beet cyst nematode Heterodera schachtii is able to infect Arabidopsis plants and induce feeding sites in the root. These syncytia are the only source of nutrients for the nematodes throughout their life and are a nutrient sink for the host plant.

Environmental drivers influencing the ambrosia beetle community: The primary role of geographic and climatic drivers in chestnut‐growing areas

open access: yesAgricultural and Forest Entomology, EarlyView.
Ethanol‐baited traps were placed in cultivated chestnut orchards (a) and mixed environments with assorted tree composition (b), over a 2‐year monitoring period in two valleys (NW Italy). A total of 118,286 ambrosia beetles was collected, representing six species.

Organic and inorganic sulfur transport in the xylem sap and the sulfur budget of Picea abies trees

open access: yes, 2022
S.1-9 : Ill., Lit.Temporal changes in inorganic and organic sulfur compounds (sulfate, glutathione, cysteine methionine) were analyzed in xylem sap of 40-year-old Norway spruce (Picea abies (L.) Karst.) trees growing on acidic soils at a healthy and a ...

Factors affecting early plant survival in restoration of Mediterranean‐type climate shrublands

open access: yesConservation Science and Practice, EarlyView.
We undertook post‐fire restoration in southern California's shrubland with some portion of plants receiving supplemental irrigation. After 2.5 years survival was higher in California sage scrub (CSS) versus chaparral species and only slightly higher in irrigated individuals.

On the Model of Transport of Salt Solution in a Xylem

open access: yesIndian Journal of Advanced Mathematics
We consider a model for vertical lifting of an aqueous solution of salts in a xylem. We analyzed changes of movement of the considered solution depending on various parameters. We consider an analytical approach for analysis of the considered model. The approach gives a possibility to take into account changes of parameters in space and time, as well ...
