Evaluation of Three New Citrus Rootstocks under Boron Toxicity Conditions

open access: yes, 2021
Boron (B) toxicity is a common limiting factor both in arid and semiarid regions, such as the Mediterranean Basin. Citrus trees are sensitive to B-toxicity, which generates a negative impact in citrus orchards.

Genome‐wide analysis of the AP2/ERF gene family in Rheum officinale Baill.: Evolution and expression profiling during plant development, abiotic stresses, and exogenous hormone responses

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The APETALA2/ethylene‐responsive factor (AP2/ERF) superfamily plays a central role in plant metabolism, stress responses, and hormone signaling. Rheum officinale Baill. is an important traditional medicinal plant whose roots and rhizomes are rich in anthraquinones and other secondary metabolites.

Engineering the bacterial nutrition strategy to control plant diseases

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 6, Page 1601-1603, June 2026.
This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.

RNAi‐Mediated Attenuation of CsCalS7‐Related Transcripts Mitigates Callose Accumulation and Huanglongbing Symptoms

open access: yesMolecular Plant Pathology, Volume 27, Issue 6, June 2026.
Partial CsCalS7 suppression reduces phloem callose, starch accumulation and huanglongbing symptoms, supporting a threshold‐based host tolerance. ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide and is characterised by excessive callose deposition at sieve plates, which has been associated with impaired carbohydrate ...

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2933-2945, June 2026.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Community Analysis of Arbuscular Mycorrhizal Fungi in Roots of Poncirus trifoliata and Citrus reticulata Based on SSU rDNA

open access: yesThe Scientific World Journal, 2014
Morphological observation of arbuscular mycorrhizal fungi (AMF) species in rhizospheric soil could not accurately reflect the actual AMF colonizing status in roots, while molecular identification of indigenous AMF colonizing citrus rootstocks at present ...
