Hydraulic function of medullary bundles in a tropical root climber

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

Cellular basis for blade splitting in bull kelp, Nereocystis luetkeana

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Blade splitting in bull kelp, Nereocystis luetkeana is central to thallus development and function, yet the cellular basis of this process remains poorly understood. Two historical models proposed contrasting mechanisms: One attributes blade separation primarily to programmed cell death, whereas the other suggests mechanical tearing ...

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Vascularização foliar e anatomia do pecíolo de Melastomataceae do cerrado do Estado de São Paulo, Brasil Leaf vasculature and petiole anatomy of Melastomataceae from the cerrado of the São Paulo State, Brazil

open access: yesActa Botânica Brasílica, 2004
Foram estudados o pecíolo e a vascularização foliar de 22 espécies de Melastomataceae do cerrado do Estado de São Paulo. A análise da vascularização mostrou que, embora venação acródroma seja constante para todos os representantes, determinados ...

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Impact on the scape of Farfugium japonicum var. japonicum (Asteraceae) under strong wind conditions based on morphological and mechanical analyses

open access: yesFrontiers in Plant Science
Adaptation of Farfugium japonicum (L.) Kitam. var. japonicum (Asteraceae) to the strong wind environment of coastal areas has been shown to reduce lamina size and shorten petioles; however, their effects on other traits of this species remain unknown ...
