Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, EarlyView.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Function and regulation of transcription factors involved in root apical meristem and stem cell maintenance

Frontiers in Plant Science, 2015
Plant roots are essential for overall plant development, growth and performance by providing anchorage in the soil and uptake of nutrients and water. The primary root of higher plants derives from a group of pluripotent, mitotically active stem cells ...

Transcriptome profiling reveals phase-specific gene expression in the developing barley inflorescence

Crop Journal, 2020
The shape of an inflorescence varies among cereals, ranging from a highly branched panicle in rice to a much more compact spike in barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.).

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Effect of cytokinins on shoot apical meristem in Nicotiana tabacum [PDF]

Archives of Biological Sciences, 2012
Cytokinins are involved in plant cell proliferation leading to plant growth and morphogenesis. The size, activity and maintenance of the shoot apical meristem (SAM) are defined by a balanced rate of mitotic cell divisions and functional cell ...

A timing mechanism for stem cell maintenance and differentiation in the Arabidopsis floral meristem [PDF]

Genes & Development, 2009
Developmental regulation of the floral meristem ensures that plants of the same species have similarly sized flowers with a fixed number of floral organs. The maintenance of stem cells in the floral meristem is terminated after the production of a fixed number of floral organ primordia. Precise repression of the

Renewal bud traits as a link between whole plant traits and herbaceous species phenology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Overwintering below‐ground buds and organs determine spring regrowth of perennial herbs in temperate regions. This effect could also manifest further in the timing and duration of plant growth and flowering and has been documented in some species and organ types ...

PHB3 Maintains Root Stem Cell Niche Identity through ROS-Responsive AP2/ERF Transcription Factors in Arabidopsis

Cell Reports, 2018
Summary: The root stem cell niche, which is composed of four mitotically inactive quiescent center (QC) cells and the surrounding actively divided stem cells in Arabidopsis, is critical for growth and root development.

Extending plant water‐use strategies to flowers: Evidence from trait correlations across plant organs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Despite the importance of flowers to plant fitness, it remains unclear whether flowers display ecophysiological strategies and how floral traits are associated with leaf economic traits.
