The role of salicylic acid and benzothiadiazole in decreasing phytoplasma titer of sugarcane white leaf disease

Scientific Reports, 2021
The objective of this research was to study the effect of Benzothiadiazole (BTH) and Salicylic acid (SA) on the systemic acquired resistance (SAR) of sugarcane the phytoplasma associated with the sugarcane white leaf (SCWL) disease.

Molecular detection and identification of a ‘Candidatus Phytoplasma solani’-related strain associated with pumpkin witches’ broom in Xinjiang, China

Phytopathologia Mediterranea, 2021
Pumpkin plants showing symptoms of witches’ broom (PuWB) were observed in Xinjiang Uyghur autonomous region, China, in September 2018. A phytoplasma was detected in symptomatic plants by PCR amplifying portions of the 16S ribosomal and tuf genes.

Genome-wide analysis of the WRKY gene family and their positive responses to phytoplasma invasion in Chinese jujube

BMC Genomics, 2019
Background The WRKY gene family is one of the most important families in higher plants. As transcription factors, they actively respond to biotic and abiotic stress and are also involved in plant development. Chinese jujube (Ziziphus jujuba Mill.) is the

Comparison of Traditional and Next-Generation Approaches for Uncovering Phytoplasma Diversity, with Discovery of New Groups, Subgroups and Potential Vectors

Biology, 2022
Despite several decades’ effort to detect and identify phytoplasmas (Mollicutes) using PCR and Sanger sequencing focusing on diseased plants, knowledge of phytoplasma biodiversity and vector associations remains highly incomplete.

‘Candidatus Phytoplasma solani’: From infection to all‐round characterisation of distinct tuf‐type strains with different virulence in tomato plants

Annals of Applied Biology, EarlyView.
‘Candidatus Phytoplasma (Ca. P.) solani’ is associated with bois noir (BN) of grapevine and stolbur of solanaceous plants and is primarily transmitted by Hyalesthes obsoletus Signoret. Four tuf‐a and five tuf‐b1 ‘Ca. P. solani’ strains were transmitted to tomato plants (cv. Micro‐Tom) by using bait‐plants and by capturing H.

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

Journal of Applied Entomology, EarlyView.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

Pathogenic fungus Ustilago maydis exploits the lateral root regulators to induce pluripotency in maize shoots

New Phytologist, EarlyView.
Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown.

Insect vectors transmitting Phytoplasma to vegetables in Eastern Visayas Philippines

Annals of Tropical Research, 2022
TPhytoplasma diseases are found affecting vegetables in Eastern Visayas, Philippines. Identifying the insect vectors that transmit phytoplasma in the field is necessary for the management of this disease. This study was conducted to identify the vectors

‘Candidatus Liberibacter Asiaticus’ Effector SECP8 Subverts Salicylic Acid‐Mediated Citrus Immunity via a Two‐Pronged Impairment of CsTCP15 Dimerization

Plant Biotechnology Journal, EarlyView.
ABSTRACT Citrus Huanglongbing (HLB), a devastating disease caused by the unculturable bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), poses a severe threat to global citrus production. CLas secretes effectors to suppress host immune responses and facilitate its colonisation. Previously, the CLas effector SECP8 (CLIBASIA_05330) has been identified

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.
