Metabolite profile changes in xylem sap and leaf extracts of Strategy I plants in response to iron deficiency and resupply

open access: yesFrontiers in Plant Science, 2011
The metabolite profile changes induced by Fe-deficiency in leaves and xylem sap of several Strategy I plant species have been characterized. We have confirmed that Fe deficiency causes consistent changes both in the xylem sap and leaf metabolite profiles.

Protein profile of Beta vulgaris leaf apoplastic fluid and changes induced by Fe deficiency and Fe resupply

open access: yesFrontiers in Plant Science, 2015
The fluid collected by direct leaf centrifugation has been used to study the proteome of the sugar beet apoplastic fluid as well as the changes induced by Fe deficiency and Fe resupply to Fe-deficient plants in the protein profile.

Effects of cropland abandonment and afforestation on soil redistribution in a small Mediterranean mountain catchment

open access: yesInternational Soil and Water Conservation Research, 2023
In slopes of Mediterranean mid-mountain areas, land use and land cover changes linked to the abandonment of cropland activity affect soil quality and degradation and soil redistribution; however, limited attention has been paid to this issue at catchment

The effects of foliar fertilization with iron sulfate in chlorotic leaves are limited to the treated area. A study with peach trees (Prunus persica L. Batsch) grown in the field and sugar beet (Beta vulgaris L.) grown in hydroponics

open access: yesFrontiers in Plant Science, 2014
Crop Fe deficiency is a worldwide problem. The aim of this study was to assess the effects of foliar Fe applications in two species grown in different environments: peach (Prunus persica L. Batsch) trees grown in the field and sugar beet (Beta vulgaris L.

Diversity of gene expression responses to light quality in barley

open access: yesScientific Reports, 2023
Light quality influence on barley development is poorly understood. We exposed three barley genotypes with either sensitive or insensitive response to two light sources producing different light spectra, fluorescent bulbs, and metal halide lamps, keeping
