3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

miRVIT: A Novel miRNA Database and Its Application to Uncover Vitis Responses to Flavescence dorée Infection

Frontiers in Plant Science, 2018
Micro(mi)RNAs play crucial roles in plant developmental processes and in defense responses to biotic and abiotic stresses. In the last years, many works on small RNAs in grapevine (Vitis spp.) were published, and several conserved and putative novel ...

Auxin‐Induced Nicotine Inhibition Is Mediated by NaARF5 Through the Suppression of NaERF1‐Like Expression and Interaction With NaERF1‐Like in Nicotiana attenuata

Plant Biotechnology Journal, EarlyView.
ABSTRACT Nicotine is the most abundant alkaloid produced by Nicotiana species against insect herbivores. Although it has been known for decades that auxin can strongly inhibit nicotine biosynthesis, the underlying mechanisms have remained unclear.

Deficiencies in jasmonate-mediated plant defense reveal quantitative variation in Botrytis cinerea pathogenesis.

PLoS Pathogens, 2010
Despite the described central role of jasmonate signaling in plant defense against necrotrophic pathogens, the existence of intraspecific variation in pathogen capacity to activate or evade plant jasmonate-mediated defenses is rarely considered ...

A Jasmonate-Activated MYC2–Dof2.1–MYC2 Transcriptional Loop Promotes Leaf Senescence in Arabidopsis

The Plant Cell, 2019
Dof2.1 and MYC2 form a feed-forward transcriptional loop that enhances jasmonate-induced leaf senescence in Arabidopsis. DNA binding-with-one-finger (Dof) proteins are plant-specific transcription factors closely associated with a variety of ...

Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

Plant Biotechnology Journal, EarlyView.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

Molecular studies of Arabidopsis and Brassica with focus on resistance to Leptosphaeria maculans [PDF]

, 2001
Blackleg caused by Leptosphaeria maculans is a widespread fungal disease on B~assica napus (oilseed rape). In contrast, Arabidopsis thaliana and B. nigra are in general highly resistant. This study presents results from genomic interaction between the A.

Repression of the auxin response pathway increases Arabidopsis susceptibility to necrotrophic fungi

, 2008
In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid (SA), jasmonic acid (JA), ethylene, and abscisic acid.

JASSY, a chloroplast outer membrane protein required for jasmonate biosynthesis

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Jasmonates are indispensable for plant growth, as well as for adaptation to biotic and abiotic stresses. The synthesis of jasmonates is initiated in the chloroplast, where the precursor, 12-oxophytodienoic acid (OPDA) is derived from plastid
