Auxin-responsive DR5 promoter coupled with transport assays suggest separate but linked routes of auxin transport during woody stem development in Populus.

PLoS ONE, 2013
Polar auxin transport (PAT) is a major determinant of plant morphology and internal anatomy with important roles in vascular patterning, tropic growth responses, apical dominance and phyllotactic arrangement.

Rice Orange Leaf Phytoplasma Imp Protein Blocks G–M Interaction by Binding Glycoprotein G to Suppress Rice Stripe Mosaic Virus Infection

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants frequently encounter multiple pathogens concurrently, yet the molecular bases of pathogen–pathogen interactions during mixed infections remain largely unresolved. Here we show that co‐infection of rice by Rice orange leaf phytoplasma (ROLP) and Rice stripe mosaic virus (RSMV) markedly suppresses RSMV proliferation in both host plants ...

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.

Hydraulic Strategies of Cool‐Temperate Trees and Lianas Against Freeze–Thaw Embolism: Is Cold Winter More Severe on Lianas?

Plant, Cell &Environment, EarlyView.
ABSTRACT Lianas are abundant and influential in tropical forests but decline sharply in cooler regions. This pattern has been attributed to their reliance on a small number of large vessels, which are vulnerable to freeze–thaw embolism. However, the hydraulic functioning of lianas in cooler regions remains poorly understood.

Differences in the Structural Chemical Composition of the Primary Xylem of Cactaceae: A Topochemical Perspective

Frontiers in Plant Science, 2019
The xylem of Cactaceae is a complex system with different types of cells whose main function is to conduct and store water, mostly during the development of primary xylem, which has vessel elements and wide-band tracheids. The anatomy of primary xylem of

Integrated Analysis of Grapevine Responses to Winter Pruning Reveals Temperature‐Associated, Polyphenol‐Rich Xylem Occlusions

Plant, Cell &Environment, EarlyView.
ABSTRACT Perennial crops are continually wounded throughout cultivation. To limit pathogen infection and tissue dehydration, plants have evolved a range of wound responses that protect damaged tissues. These responses include changes in gene expression and the synthesis of protective compounds such as polyphenols.

Microbial Partnerships for Sustainable Soybean Cultivation: Mechanisms, Applications and Prospects

Plant, Cell &Environment, EarlyView.
ABSTRACT Soybean production is increasingly threatened by fluctuating environmental conditions and nutrient limitations. While synthetic fertilisers can alleviate these constraints, their excessive use has raised concerns regarding long‐term soil health. Consequently, leveraging beneficial soil microbes, a diverse group of microorganisms that reside in

Biological basis of tree-ring formation: a crash course

Frontiers in Plant Science, 2016
Wood is of crucial importance for man and biosphere. In this mini review, we present the fundamental processes involved in tree-ring formation and intra-annual dynamics of cambial activity, along with the influences of the environmental factors.

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

Plant 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.
