Grapevine Yield and Leaf Area Estimation Using Supervised Classification Methodology on RGB Images Taken under Field Conditions [PDF]

, 2012
The aim of this research was to implement a methodology through the generation of a supervised classifier based on the Mahalanobis distance to characterize the grapevine canopy and assess leaf area and yield using RGB images.

Plant Peptides on the Rise: From Historical Insight to Future Applications

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Microscope observations of Botryosphaeriaceae spp. in the presence of grapevine wood

Phytopathologia Mediterranea, 2020
Grapevine trunk diseases (GTD) are important threats to long-term longevity, productivity, and profitability in all grape production systems. Botryosphaeria dieback is caused by at least 32 Botryosphaeriaceae fungi.

A Dynamic Change of Microglial States Occurs During the Transition From Photoreceptor Degeneration to Regeneration in Zebrafish pde6c Mutants

Glia, Volume 74, Issue 6, June 2026.
Zebrafish pde6c mutants undergo photoreceptor degeneration from 5 dpf, but rods regenerate from 4 wpf. scRNA‐seq of retinal microglia reveals dynamic change of states between 5 dpf and 4 wpf. Two states emerge specifically during regeneration. ABSTRACT Microglia, brain‐resident immune cells, maintain brain homeostasis.

From pathogens to partners: temporal and biogeographical patterns in fungal associations of alien trees

New Phytologist, Volume 250, Issue 5, Page 3381-3395, June 2026.
Summary Alien trees reshape belowground fungal communities, but the factors governing the balance between mutualists and pathogens remain unclear. We tested whether residence time, mycorrhizal type, and biogeographical origin shape this balance, and whether alien stands differ from native vegetation. We sampled soils beneath 73 alien tree species in 48

Impact of software tools and kinetic model selection on myocardial blood flow and flow reserve quantitation in 13N‐ammonia PET

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background Quantitative assessment of myocardial perfusion using 13N‐ammonia PET with compartmental modeling enables evaluation of myocardial flow reserve (MFR) and prediction of patient prognosis. However, the reliability of these assessments can depend on the analytical methods used for quantitation.

Neofusicoccum parvum Associated with Grapevine Trunk Diseases in Chile

Plant Disease, 2011
During 2009 and 2010, a survey (n = 520) of diseased grapevines (Vitis vinifera L.) was done in vineyards located in Maipo and Colchagua valleys (33°43′ to 34°36′S) in Chile. Symptoms of trunk diseases (TD) were observed on >10-year-old grapevines and consisted of short internodes, dead spurs and arms, and dieback.

In search of solutions to grapevine trunk diseases through “crowd-sourced” science [PDF]

Frontiers in Plant Science, 2013
Trunk diseases create tremendous problems for the viticulture industry causing significant economical losses due to reduced yields, increased crop management costs for cultural and chemical preventive measures, and shortened life span of the vines (Munkvold et al., 1994; Bertsch et al., 2013).

Deciphering Transcriptomic and Metabolomic Wood Responses to Grapevine Trunk Disease-Associated Fungi

PhytoFrontiers
Esca is one of the main grapevine trunk diseases affecting vineyards worldwide. Phaeoacremonium minimum and Phaeomoniella chlamydospora are thought to be two of the main causal agents of this disease.

Nanoparticle‐Mediated Immunometabolic‐Epigenetic Remodeling Enhances Schwann Cell‐Macrophage Interaction for Sciatic Nerve Regeneration

Advanced Science, Volume 13, Issue 25, 4 May 2026.
A biomimetic Prussian White nanoparticle (PW) is engineered to achieve long‐term local retention and orchestrate immunometabolic‐epigenetic remodeling for sciatic nerve regeneration. PW directly targets hexokinase 2 to suppress glycolysis, thereby elevating α‐ketoglutarate and driving Kdm4a/b‐mediated demethylation of H3K9me3.
