Knockout of MDHAR Paralogs Suggests Broader Regulatory Roles Beyond Ascorbic Acid Recycling in Lettuce

Ugo Rogo, Samuel Simoni, Ambra Viviani, Claudio Pugliesi et autres

Ascorbic acid (AsA) is a key antioxidant and nutrient in plants, regulating reactive oxygen species (ROS) levels and maintaining cellular redox homeostasis. The AsA recycling pathway sustains AsA pools by restoring its oxidized forms, ensuring intracellular balance. Among the enzymes involved, monodehydroascorbate …

Improving Crop Tolerance to Abiotic Stress for Sustainable Agriculture: Progress in Manipulating Ascorbic Acid Metabolism via Genome Editing

Ugo Rogo, Ambra Viviani, Claudio Pugliesi, Marco Fambrini et autres

Plants often encounter challenging environmental factors, including intense sunlight, drought, extreme heat, cold temperatures, salinity, excessive metals, and nutrient shortages, which can heavily affect their growth and survival. In this regard, L-ascorbic acid (AsA) is not only an essential nutrient for human …

Priority actions for Fusarium head blight resistance in durum wheat: Insights from the wheat initiative

Ambra Viviani, Jemanesh K. Haile, W. G. Dilantha Fernando, Carla Ceoloni et autres

Fusarium head blight (FHB), mainly caused by Fusarium graminearum and Fusarium culmorum, is a major wheat disease. Significant efforts have been made to improve resistance to FHB in bread wheat (Triticum aestivum), but more work is needed for durum wheat (Triticum turgidum …

Identification and Biological Characterization of Candidate Genes for Resistance to Soil-Borne Cereal Mosaic Virus in Durum Wheat using CRISPR-Cas9 Genome Editing Systems

Lorenzo Calzini, Matteo Bozzoli, Cristian Forestan, Ambra Viviani et autres

Soil-Borne Cereal Mosaic Virus (SBCMV) significantly harms wheat yields and grain quality. To sustainably meet rising food demands, genetic resistance of plants to the virus is the most effective plant protection strategy, relying on New Genomics Techniques due to the low rate …

Loci relevant for Yellow Rust Resistance in Durum Wheat adapted to the Mediterranean environments identified in cultivated and landrace germplasm through genome-wide association study

Liu Chunyi, Francesco De Sario, Muhammad Awais Farooq, Jad B Novi et autres

Yellow rust (YR), caused by Puccinia striiformis f. sp. tritici, is a devastating fungal disease posing a significant threat to global wheat production. A genetic survey for loci controlling resistance in tetraploid wheat germplasm was carried out based on the Global Durum …

Genetics of drought tolerance in cereals

Ambra Viviani, Roberto Tuberosa, Marco Maccaferri

This chapter discusses some of the latest findings related to the genetics of drought resistance of the world's most widely grown cereals. The chapter starts with rice because of its key role as an ancestral founder species and phylogenetically pivotal role for …

Spray application of BcBmp3-dsRNA delivered by layered double hydroxide (LDH) clay nanosheets reduces virulence of Botrytis cinerea on Lactuca sativa: first results.

Maria Spada, Ambra Viviani, Claudio Pugliesi, Marco Fambrini et autres

Recently novel strategies based on the use of RNA interference (RNAi) are rising up in the crop protection scenario. Spray-induced gene silencing (SIGS) is a potential strategy for plant disease management, whereby nucleotide sequence-specific double-stranded RNA (dsRNA) can be sprayed onto a …

L-Ascorbic acid in plants: from biosynthesis to its role in plant development and stress response

Ambra Viviani, Marco Fambrini, Tommaso Giordani, Claudio Pugliesi

L-Ascorbic acid (AsA; vitamin C), is a common antioxidant in nature. In plants, it plays an important role in photosynthesis as it eliminates reactive oxygen species (ROS) generated during electron transport. Unlike animals that use D-Glucuronate as a precursor, plants produce AsA …
