Identification and analysis of oxygen responsive microRNAs in the root of wild tomato (S. habrochaites) [PDF]

BMC Plant Biology, 2019
Background MicroRNA (miRNA) are key players in regulating expression of target genes at post-transcriptional level. A number of miRNAs are implicated in modulating tolerance to various abiotic stresses. Waterlogging is an abiotic stress that deters plant

Chemoenzymatic Synthesis of (4R,7R)‐Zingiberene Enables Construction of nor‐Sesquiterpene Semiochemical Analogs [PDF]

Chembiochem
A five‐enzyme chemoenzymatic synthesis of the insect‐repellent (4R,7R)‐zingiberene from the wild tomato (Solanum habrochaites) has been developed. This approach enabled the elucidation of the sesquiterpene synthase cyclization mechanism of (2Z,6Z)‐farnesyl pyrophosphate and bypasses classic biosynthetic constraints of prenyltransferase chain extension ...

Pan-genome cloning and expression analysis of S-RNase homologous gene in SI and SC of different tomato species [PDF]

Scientific Reports
Flowering plants encode polymorphic ribonucleases (S-RNases) that determine the self-incompatibility (SI) phenotype of the style. The pan-genome cloning and expression analysis of the S-RNase homologous genes in SI and self-compatibility (SC) lines of ...

The Role of Two Glycoalkaloid Metabolism Genes in α-Tomatine Biosynthesis and Basal Defence in Tomato. [PDF]

Mol Plant Pathol
We generated knockout mutants of two tomato genes proposed to be involved in α‐tomatine biosynthesis by genome editing. SlGAME2 mutants contained unaltered α‐tomatine contents; this gene is not involved in its synthesis. SlGAME4 mutants did not accumulate any glycoalkaloids but instead redirected resources towards steroidal saponin synthesis.

Chlorophyll Fluorescence-Based High-Throughput Phenotyping Reveals Mechanisms and Enables Rapid Screening of Desiccation-Tolerant Wild Tomato Species [PDF]

Plants
Desiccation tolerance is a critical adaptive trait that enables plants to survive extreme water loss, yet its physiological basis in tomato and its wild relatives remains poorly understood.

Current Understanding of Cell-Surface Immune Receptors for MAMPs and Plant Parasites in the Solanaceae Family. [PDF]

Mol Plant Pathol
Members of the Solanaceae family use diverse cell‐surface receptors to sense microbes and parasites, triggering immune responses that vary across species and cultivars. ABSTRACT Cell‐surface receptors play a central role in plant defence by enabling the perception of microbial signatures upon initial contact, activating immune responses and protecting ...

Complex engineering of Solanum alkaloids structural diversity in Nicotiana benthamiana. [PDF]

Plant Biotechnol J
Summary Transient expression in Nicotiana benthamiana offers a powerful and versatile platform for rapid production of complex specialized metabolites. Steroidal glycoalkaloids (SGAs) and steroidal saponins produced by members of the Solanaceae family are known for their diverse structures and activities including antimicrobial, anticancer, antiviral ...

Phylogenomic and super-pangenome analyses unveil the genetic landscape of tomato evolution and domestication. [PDF]

Plant Biotechnol J
Summary The tomato (Solanum lycopersicum L.), a principal fruit crop, exhibits significant genetic diversity shaped by domestication and breeding. Analysis of the gene‐based super‐pangenome, a catalogue of all genes across diverse genome‐sequenced tomatoes, has not yet been fully explored.

Grafting Tomato ‘Nairouz F1’ onto Interspecific Hybrids for Induced Antibiosis and Antixenosis Resistance to Tetranychus urticae Koch via Chlorogenic Acid Synthesis [PDF]

BMC Plant Biology
Background This study is the first research to investigate the potential of grafting to induce tomato resistance to two-spotted spider mite (TSSM), Tetranychus urticae Koch. TSSM can cause up to 50% yield loss of tomato.

A multifunctional sesquiterpene synthase integrates with cytochrome P450s to reinforce the terpenoid defense network in maize. [PDF]

Plant J
SUMMARY Terpenoids, the largest and most structurally diverse class of plant natural products, play essential roles in maize defense and ecological interactions. In this study, we identified and functionally characterized a sesquiterpenoid‐based defense pathway in maize centered on α‐santalenoic acid, a pathogen‐inducible sesquiterpenoid antibiotic ...
