SlMED25‐SlPHR3‐SlSPX2 module fine‐tunes SlPHR3‐mediated transcriptional activation of phosphate starvation response in tomato

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Mediator subunit SlMED25 and the co‐repressor SlSPX2 competitively bind the N‐terminal domain of the phosphate starvation response transcription factor SlPHR3 in tomato to form a sensitive molecular switch, which dynamically modulates phosphate starvation responses and maintains phosphate homeostasis, offering valuable targets for breeding low ...

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

Características adaptativas da associação simbiótica e da fixação biológica do nitrogênio molecular em plantas jovens de Lonchocarpus muehlbergianus Hassl., uma leguminosa arbórea nativa do Cerrado

open access: yesRodriguésia
O nitrogênio mineral afeta negativamente a simbiose e a fixação biológica do nitrogênio em plantas cultivadas. Entretanto, este efeito não é verificado em algumas espécies arbóreas, pouco estudadas até o momento.

ARF6 integrates auxin and gibberellin signaling to promote stone cell lignification in pear via the HB49‐MYB169 module

open access: yesNew Phytologist, EarlyView.
Summary Stone cells originate from secondary cell wall thickening and contain abundant lignin. Their excessive accumulation compromises pear fruit quality, yet the endogenous hormonal mechanisms governing stone cell formation remain unclear. Here, co‐expression network analysis using transcriptome data – the flesh of 206 sand pear accessions sampled at

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

open access: yesNew 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 ...

C4 photosynthetic anatomy is associated with higher leaf hydraulic conductance and capacitance in Alloteropsis semialata

open access: yesNew Phytologist, EarlyView.
Bulk leaf capacitance (Cbulk) in relation to bundle sheath area (BSA) and leaf dimensions in Alloteropsis semialata plants differing in photosynthetic type (C3, C3–C4 or C4) and ploidy level (2x, 6x or 12x). Summary The evolution of C4 photosynthesis requires biochemical innovations to be coordinated with anatomical modifications.

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Translational profiles of interfascicular fibers and xylem cells connect sugar transporters to xylem development

open access: yes
In plant cells, carbohydrates serve multiple essential roles, including central metabolism, storage as soluble or insoluble sugars, and polysaccharide synthesis. They also act as signaling molecules and protective agents during abiotic stress responses.

Gallic Acid‐Responsive microRNAs Reprogram Lignification During Drought Acclimation Process in Spearmint

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Mentha spicata L. (spearmint) is a high‐value aromatic and medicinal species, whose productivity is strongly affected by water deficit. Nevertheless, the molecular mechanisms underlying drought acclimation in this mint remain largely unexplored. Thus, here, we investigated the microRNA‐mediated regulatory processes triggered in M.

Systemic Delivery of Functional Proteins Into Plants Using an Engineered Membrane Translocation Domain

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Protein‐based biopesticides and biostimulants are critical for the future of sustainable agriculture, yet their utility is severely limited by inefficient delivery into plant cells. Traditional cell‐penetrating peptides enable protein uptake but lack the efficiency, systemic activity and scalability required for crop production.
