Entangled Foodways and Livelihood Pathways: Cinnamon, State Interventions, and Everyday Life in Hmong Communities of Northern Vietnam

Journal of Agrarian Change, EarlyView.
ABSTRACT The agroecological practices of ethnic minority farmers in Vietnam's northern uplands are being reshaped by intersecting pressures of land‐use reform, market integration, and state‐backed crop promotion. Among Hmong communities in the south of Lào Cai Province (former Yên Bái Province) cinnamon was once valued primarily for its medicinal ...

Demography of evergreen and deciduous oaks in a mixed oak savanna: insights from a long‐term experiment

Ecosphere, 2019
The co‐existence of evergreen and deciduous oaks in Mediterranean‐climate savannas has motivated comparative studies on species’ physiological adaptations to light and drought, establishment niche differences in acorn production, dispersal and seedling ...

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Structure and dynamics of a Cariniana estrellensis (Lecythidaceae) population in a fragment of Atlantic Forest in Minas Gerais, Brazil

Rodriguésia
We aimed to describe population structure and dynamics of Cariniana estrellensis (Raddi) Kuntze to test the hypothesis that this species survives in the forest by forming a seedling bank.

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, EarlyView.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

Effects of Plant Health-Protecting Product Applications on the Root-Associated Microbiota of Apple Saplings and Strawberries

Phytobiomes Journal
The root-associated microbiome has been of keen research interest due to its large potential for increasing plant performance. In agricultural systems, the use of plant health-protecting products (PHPPs) is essential for obtaining high yields and quality. Knowledge about the impact of PHPP applications on the root-associated microbiome remains limited,

Analysis of BpbHLH Gene Family Responsive to MeJA Signalling in Betula platyphylla Suk. and Functional Mechanisms of BpbHLH42/44 in Genetic Improvement and Triterpenoid Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT The basic helix–loop–helix (bHLH) transcription factor family regulates plant secondary metabolism, development and stress responses. Although triterpenoids such as betulinic acid (BA), betulin (BT) and oleanolic acid (OA) from Betula platyphylla Suk.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.
