Virus-Inducible Activation of Hypersensitive Response Confers Broad-Spectrum Resistance to Diverse Viruses in Plants. [PDF]

Mol Plant Pathol
Using a virus‐inducible promoter to drive the expression of the Avr4/Cf‐4 gene pair can trigger a hypersensitive response upon viral infection, which confers plants broad‐spectrum resistance to geminiviruses. ABSTRACT The hypersensitive response (HR) is a powerful plant defence mechanism that restricts pathogen spread through localised cell death ...

Functional Scanning of Apple Geminivirus Proteins as Symptom Determinants and Suppressors of Posttranscriptional Gene Silencing

Viruses, 2018
Apple geminivirus (AGV) is a recently identified geminivirus which is isolated from the apple tree in China. We carried out functional scanning of apple geminivirus proteins as symptom determinants and suppressors of posttranscriptional gene silencing ...

Construction and Biological Characterization of Papaya Leaf Curl Guangdong Virus Infectious cDNA Clone. [PDF]

Microb Biotechnol
Viral diseases are important diseases on cash crops such as passion fruit, among which PaLCuGDV is one of the more severe in recent years. We constructed an infectious clone of PaLCuGDV for the first time and confirmed its infectivity through biological assays.

Engineering Conditional Transgene Expression in Nicotiana benthamiana. [PDF]

Plant Biotechnol J
ABSTRACT Nicotiana benthamiana has emerged as a premier plant biofactory for recombinant protein and metabolite production due to its high metabolic versatility, ease of cultivation and permissiveness to transient expression vectors. However, challenges such as transgene silencing, low yields and metabolic toxicity limit its scalability. Synthetic gene

REPercussions: how geminiviruses recruit host factors for replication

Frontiers in Microbiology, 2023
Circular single-stranded DNA viruses of the family Geminiviridae encode replication-associated protein (Rep), which is a multifunctional protein involved in virus DNA replication, transcription of virus genes, and suppression of host defense responses ...

Plant responses to geminivirus infection: guardians of the plant immunity

Virology Journal, 2021
Background Geminiviruses are circular, single-stranded viruses responsible for enormous crop loss worldwide. Rapid expansion of geminivirus diversity outweighs the continuous effort to control its spread.

Plant Defense and Viral Counter-Defense during Plant–Geminivirus Interactions

Viruses, 2023
Geminiviruses are the largest family of plant viruses that cause severe diseases and devastating yield losses of economically important crops worldwide. In response to geminivirus infection, plants have evolved ingenious defense mechanisms to diminish or

WRKY1 represses the WHIRLY1 transcription factor to positively regulate plant defense against geminivirus infection.

PLoS Pathogens, 2023
Geminiviruses constitute the largest group of known plant viruses and cause devastating diseases and economic losses in many crops worldwide. Due to limited naturally occurring resistance genes, understanding plant antiviral defense against geminiviruses

Requirements for the Packaging of Geminivirus Circular Single-Stranded DNA: Effect of DNA Length and Coat Protein Sequence

Viruses, 2020
Geminivirus particles, consisting of a pair of twinned isometric structures, have one of the most distinctive capsids in the virological world. Until recently, there was little information as to how these structures are generated.

Geminiviruses Associated with the Weed Species Ageratum conyzoides, Centipeda minima, Porophyllum ruderale, and Spilanthes iabadicensis from Java, Indonesia

Microbiology Indonesia, 2012
Geminivirus has a wide host range including cultivated plants and weeds. Infected weeds may play an important role in disease epidemic. Unfortunately, little is known about weeds species that may serve as alternative host for Geminivirus.
