Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, Volume 49, Issue 8, Page 5210-5227, August 2026.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

Stomata and plasmodesmata

Protoplasma, 1979
In developing epidermal tissue ofPhaseolus vulgare L. complete plasmodesmatal connections occurred between guard cells and epidermal cells and between sister guard cells of a stoma but they were not seen in fully differentiated tissue. However, incomplete, aborted plasmodesmata were occasionally seen in the common guard/epidermal cell wall, usually ...

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

Plant, Cell &Environment, Volume 49, Issue 8, Page 5563-5579, August 2026.
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.

Quantification of Protein Enrichment at Plasmodesmata

BIO-PROTOCOL, 2020
Intercellular communication plays a crucial role in the establishment of multicellular organisms by organizing and coordinating growth, development and defence responses. In plants, cell-to-cell communication takes place through nanometric membrane channels called plasmodesmata (PD). Understanding how PD dictate cellular connectivity greatly depends on

Highly Polygenic Control of Photosynthetic Responses to Nighttime Temperature Studied by Genomic Prediction

Plant, Cell &Environment, Volume 49, Issue 8, Page 5886-5903, August 2026.
ABSTRACT Rising nighttime temperature (Tnight) can reduce crop yields while low Tnight may restrict plant growth and development. Despite quantifiable effects of Tnight, genetic basis underlying plant responses to Tnight remains unclear. We investigated natural variation in long‐term response of effective photosynthetic efficiency (Fq’/Fm’) to Tnight ...

Systemic infection of tobacco mosaic virus is limited by upward transport and phloem unloading without coat protein

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Coat protein (CP) is widely viewed as essential for systemic infection of tobacco mosaic virus (TMV), yet the mechanistic basis of this requirement remains incompletely resolved. In this study, we show that TMV can still achieve long‐distance vascular transport in the absence of CP, but systemic infection becomes intermittent because the ...

Salicylic Acid-Induced Resistance to Cucumber mosaic virus in Squash and Arabidopsis thaliana: Contrasting Mechanisms of Induction and Antiviral Action

Molecular Plant-Microbe Interactions, 2005
Salicylic acid (SA)-induced resistance to Cucumber mosaic virus (CMV) in tobacco (Nicotiana tabacum) results from inhibition of systemic virus movement and is induced via a signal transduction pathway that also can be triggered by antimycin A, an inducer

SERRATE Regulates Floral Meristem Activity by Antagonizing SHOOT MERISTEMLESS and Repressing Cytokinin Signaling

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

Callose in leptoid cell walls of the moss Polytrichum and the evolution of callose synthase across bryophytes

Frontiers in Plant Science
IntroductionLeptoids, the food-conducting cells of polytrichaceous mosses, share key structural features with sieve elements in tracheophytes, including an elongated shape with oblique end walls containing modified plasmodesmata or pores.

Replicase-Mediated Resistance to Cucumber Mosaic Virus Does Not Inhibit Localization and/or Trafficking of the Viral Movement Protein

Molecular Plant-Microbe Interactions, 1999
Replicase-mediated resistance to cucumber mosaic virus (CMV) affects CMV replication and restricts CMV movement. Confocal laser scanning microscopic analysis of resistant plants inoculated with either CMV or potato virus X, expressing the CMV movement ...
