Iron homeostasis in the annual and perennial stem zones of Arabis alpina

Plant Biology, EarlyView.
Iron accumulates in secondary growth tissues in the perennial stem zone and is correlated with particular gene expression patterns in the perennial model plant Arabis alpina. Abstract Plants store nutrients, including the micronutrient iron, in bioavailable forms to support growth in subsequent seasons. The perennial lifestyle is preponderant in nature.

Elimination of FRDL1, a xylem‐located citrate transporter, confers tolerance to excess unchelated ferrous iron through an exclusion mechanism in rice (Oryza sativa L.)

Plant Biology, EarlyView.
Knock‐down of a xylem‐localized citrate transporter, FRDL1, reduces foliar iron concentrations and leaf symptoms under excess ferrous iron stress in rice. Abstract Iron (Fe) toxicity is a common agricultural problem that limits rice yield in various regions of Southeast Asia and Africa.

Water Released From Vessel Embolism May Temporarily Halt Further Embolism in Tropical Dipterocarp Trees. [PDF]

Plant Cell Environ
ABSTRACT The formation of air bubbles in the xylem, known as embolism, reduces hydraulic conductivity and can ultimately lead to catastrophic failure of a tree's water transport system. When a vessel embolises, it releases water into the surrounding xylem tissue.

Effects of Meloidogyne incognita on agronomic parameters and structural changes in eggplant (Solanum gilo Raddi) roots treated with Purpureocillium lilacinum

Plant Biology, EarlyView.
Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Unveiling contrasting iron efficiency strategies in common bean (Phaseolus vulgaris L.) genotypes under iron deficiency

Plant Biology, EarlyView.
Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

The impact of seasonal variations in inner bark width and xylem growth on irreversible annual stem diameter measurements

Plant Biology, EarlyView.
The seasonal variation in inner bark width differed from that of xylem growth, indicating that xylem phenology cannot be reliably assessed without cellular observations. Abstract To better interpret continuous xylem growth measurements from dendrometers, we evaluated how the widths of developing xylem and phloem, along with seasonal trends in inner ...
