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.

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

Organellar carbon metabolism is co-ordinated with distinct developmental phases of secondary xylem [PDF]

, 2019
Subcellular compartmentation of plant biosynthetic pathways in the mitochondria and plastids requires coordinated regulation of nuclear encoded genes, and the role of these genes has been largely ignored by wood researchers. In this study, we constructed

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, EarlyView.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

Using Confidence Modeling to Optimize Overall Score Quality in Hybrid Scoring Systems

Educational Measurement: Issues and Practice, Volume 45, Issue 2, Summer 2026.
Abstract In large‐scale assessments, constructed response items are often scored using hybrid scoring systems, which combine human and automated scores. In this study, we augment automated scoring with confidence modeling to strategically route difficult‐to‐score responses for human review.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Xylem Phenology of Fagus sylvatica in Rarău Mountains (Eastern Carpathians, Romania)

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
The cambium activity and the tree ring formation of European beech (Fagus sylvatica L.) from the Rarău Mountains was monitored during 2009, 2010 and 2011 in a beech - coniferous stand, representative for Eastern Carpathian mixed forests.
