Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Novel and emerging cutaneous soft tissue tumours

open access: yesHistopathology, EarlyView.
This review outlines the defining histopathological, immunophenotypic and molecular features of novel and emerging cutaneous soft tissue tumours, including hybrid superficial ALK‐rearranged myxoid spindle cell neoplasm/epithelioid fibrous histiocytoma, superficial neurocristic tumour, ALK‐rearranged epithelioid vascular neoplasm and MITF pathway ...

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

open access: yesJournal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

The preprophase band is dispensable for robust cell division orientation in wood‐forming cambium stem cells

open access: yesNew Phytologist, EarlyView.
Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

Non-Coding RNA Analyses of Seasonal Cambium Activity in Populus tomentosa

open access: yesCells, 2022
Non-coding RNA, known as long non-coding RNA (lncRNA), circular RNA (circRNA) and microRNA (miRNA), are taking part in the multiple developmental processes in plants.

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

open access: yesPlant 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

open access: yesPlant 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

Unravelling the colonization mechanism of Lasiodiplodia brasiliensis in grapevine plants

open access: yesPhytopathologia Mediterranea, 2023
Botryosphaeriaceae cause the degenerative disease Botryosphaeria dieback in many woody hosts, including grapevine. These pathogens penetrate host plants through pruning wounds, and colonize vascular tissues causing necrotic lesions, cankers, and ...

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

open access: yesJournal of Applied Entomology, Volume 150, Issue 8, Page 1088-1101, September 2026.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.
