Attaining the Promise of Geminivirus-Based Vectors in Plant Genome Editing [PDF]

Viruses
Over the last 40 years, several studies have provided evidence demonstrating that viral vectors can result in effective gene targeting/insertions in a host’s genome.

Efficient production of functional cholera toxin B subunit using geminiviral replicons in Nicotiana benthamiana [PDF]

Frontiers in Bioengineering and Biotechnology
The cholera toxin B subunit (CTB) has the potential to be a carrier molecule and an effective adjuvant for mucosal vaccines because of its ability to enhance immune responses to antigens. CTB proteins have been expressed in plant-based expression systems.

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.

Identification and characterization of a new geminivirus from soybean plants and determination of V2 as a pathogenicity factor and silencing suppressor

BMC Plant Biology, 2022
Background Soybean is one of the four major crops in China. The occurrence of viruses in soybean causes significant economic losses. Results In this study, the soybean leaves from stay-green plants showing crinkle were collected for metatranscriptomic ...

Geminiviruses and Plant Hosts: A Closer Examination of the Molecular Arms Race

Viruses, 2017
Geminiviruses are plant-infecting viruses characterized by a single-stranded DNA (ssDNA) genome. Geminivirus-derived proteins are multifunctional and effective regulators in modulating the host cellular processes resulting in successful infection.
