Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

miR172‐AP2 Controls Age‐Dependent Regeneration Competence in Populus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Populus.

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 ...

Qu-1: a transformation-and regeneration-amenable doubled haploid cell line with a reference genome sequence for genetic and functional studies in Populus

Forestry Research
Plant suspension homogeneous cells are invaluable materials for investigating molecular mechanisms underlying various biological processes. In this study, we established and characterized a doubled haploid cell line from Populus simonii × P.

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

The ASYMMETRIC LEAVES1 ortholog PagAS1a promotes xylem development and plant growth in Populus

Forestry Research
ASYMMETRIC LEAVES1 (AS1) is a central regulator of leaf polarity establishment in Arabidopsis. However, the functions of its ortholog genes in Populus are unclear.

Rhizosphere Engineering by Root Exudates: High‐Yielding Alfalfa Recruits Functional PGPR to Sustain Soil Nutrient Availability Under Long‐Term Cultivation

Plant, Cell &Environment, EarlyView.
ABSTRACT Soil nutrient transformation capacity is a critical determinant of sustainable productivity in perennial cropping systems; however, the extent to which high‐yielding crops actively regulate rhizosphere microbial assembly to maintain nutrient availability remains poorly understood.

Transcriptomic and metabolomic analysis of poplar response to feeding by Hyphantria cunea

BMC Plant Biology
Populus cathayana × canadansis ‘Xinlin 1’ (‘P.‘xin lin 1’) with the characteristics of rapid growth and high yield, is frequently attacked by herbivorous insects. However, little is known about how it defenses against Hyphantria cunea (H.

Water Released From Vessel Embolism May Temporarily Halt Further Embolism in Tropical Dipterocarp Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT The formation of air bubbles in the xylem, known as embolism, reduces hydraulic conductivity and can ultimately lead to catastrophic failure of a tree's water transport system. When a vessel embolises, it releases water into the surrounding xylem tissue.
