The Simplest Leaf Organization Found in Surveys of Several Hundred Species of Dicotyledons

open access: yes, 1951
The number of cell-layers in leaves of dicotyledons varies considerably but within fairly definite limits. Extreme thickness of epidermis or mesophyll presently retards photosynthetic activity and is usually restricted to succulents and desert types.

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Writing Big in Plant Genomes: Advances, Challenges and Strategies for Targeted Large‐Fragment DNA Insertion

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Precise genome editing has transformed plant biology and crop improvement by enabling targeted modification of endogenous loci. Beyond gene knockout and base editing, the site‐specific insertion of exogenous DNA, particularly large DNA fragments, has become a central goal for engineering complex traits, reconstructing metabolic pathways and ...

Advancements in the Regulation of Flavonoid Compounds in Monocotyledons and Dicotyledons by Plant MYB Transcription Factors

open access: yesHorticulturae
Flavonoids are essential secondary metabolites in plants, predominantly found in flowers, leaves, and fruits. They mainly include anthocyanins, proanthocyanidins, and flavonols.

MdPHYB2‐MdPIF1 Module Regulates Transcription Factors to Mediate Light‐Dependent ALA‐Induced Apple Anthocyanin Biosynthesis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Light is a primary environmental signal that induces plant anthocyanin accumulation. The plant growth regulator 5‐aminolevulinic acid (ALA) has also been proven to effectively promote anthocyanin accumulation in apple. However, the underlying regulatory mechanisms remain unknown.

Leaf Tissue‐Specific Phosphorus Allocation Is Linked to Leaf Lifespan in Chickpea Accessions

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants strategically allocate phosphorus (P) among leaf tissues to support physiological functions. However, there is limited understanding of contrasting leaf cellular P‐allocation patterns and their physiological consequences. We quantified leaf P fractions, photosynthetic P‐use efficiency (PPUE), and P‐remobilisation efficiency (PRE) in ...

Combined Phosphorus and Potassium Starvation Upregulates Sodium Accumulation by HKT1;1 in Tomato Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Na+ can substitute K+ under K+ deficiency conditions, which is denominated as beneficial Na+. Despite its relevance at the physiological level and its interest in agriculture, the mechanisms allowing its uptake and use by plants remain unclear.

Drought affects Fe deficiency‐induced responses in a purple durum wheat (Triticum turgidum subsp. durum) genotype

open access: yesPlant Biology, EarlyView.
Combined Fe deficiency and drought in durum wheat trigger interactive responses: drought suppressed root Fe uptake regardless of Fe availability, and both stresses altered phytosiderophore release, ABA level and Fe transporter gene expression, revealing a trade‐off between water and Fe. Abstract Iron (Fe) is essential for plants and humans, with over 2
