AI Article Synopsis
- The nucleotide sequence of PMWaV-3 was analyzed, revealing seven open reading frames and an untranslatable region at the 3' end.
- Based on amino acid similarities, PMWaV-3 is proposed as a new species within the PMWaV complex, with distinct differences compared to PMWaV-1 and PMWaV-2.
- Phylogenetic studies found two main clades of the Ampelovirus genus, highlighting the relationships among PMWaV-3, PMWaV-1, and other related viruses.
Article Abstract
The nucleotide sequence of Pineapple mealybug wilt associated virus-3 (PMWaV-3) (Closteroviridae: Ampelovirus), spanning seven open reading frames (ORFs) and the untranslatable region of the 3' end was determined. Based on the amino acid identities with orthologous ORFs of PMWaV-1 (54%-73%) and PMWaV-2 (13%-35%), we propose PMWaV-3 is a new species in the PMWaV complex. PMWaV-3 lacks an intergenic region between ORF1b and ORF2, encodes a relatively small, 28.8 kDa, coat protein, and lacks a coat protein duplicate. Phylogenetic analyses were used to analyze seven different domains and ORFs from members of the family Closteroviridae. Two distinct clades within the recognized genus Ampelovirus were observed; one that includes PMWaV-3 and PMWaV-1 and several GLRaVs and another that includes PMWaV-2 and GLRaV-3, the type member of the genus Ampelovirus.

The cultivation of pineapple () is threatened worldwide by mealybug wilt disease of pineapple (MWP), whose etiology is not yet fully elucidated. In this study, we characterized pineapple mealybug wilt-associated ampeloviruses (PMWaVs, family ) from a diseased pineapple plant collected from Reunion Island, using a high-throughput sequencing approach combining Illumina short reads and Nanopore long reads. Reads co-assembly resulted in complete or near-complete genomes for six distinct ampeloviruses, including the first complete genome of pineapple mealybug wilt-associated virus 5 (PMWaV5) and that of a new species tentatively named pineapple mealybug wilt-associated virus 7 (PMWaV7).

Pineapple is a globally significant tropical fruit, but its cultivation faces numerous challenges due to abiotic and biotic stresses, affecting its quality and quantity. WRKY transcription factors are known regulators of stress responses, however, their specific functions in pineapple are not fully understood. This study investigates the role of by overexpressing it in pineapple and .

In this study, mealybugs infesting bananas and plantains in Tamil Nadu, South India, are documented along with their coccinellid predators and other natural enemies. The exotic Jack Beardsley mealybug, Pseudococcus jackbeardsleyi Gimpel & Miller, was found to be a major pest of banana bunches in all localities surveyed in Tamil Nadu and the grey pineapple mealybug, Dysmicoccus neobrevipes Beardsley, was a serious pest in some isolated pockets.

Article Synopsis
- Pineapple mealybug is a major pest for pineapple production and poses trade challenges.
- Ethyl formate (EF) was tested as a potential replacement for methyl bromide fumigation, showing effective results in killing nymphs and adults of the mealybug when used at a specific concentration and temperature.
- Trials indicated that lower loading ratios of pineapples (below 30%) help achieve the required mortality levels, with no noticeable impact on the quality of the treated fruit.

Article Synopsis
- New plant diseases, including those caused by badnaviruses, pose significant threats to economically important crops like bananas, cacao, and citrus, leading to major yield losses.
- Badnaviruses, which are a type of pararetrovirus, have a unique ds DNA genome and can spread through vegetative propagating materials and insects, with some species showing a limited host range.
- Recent research has increased the known badnavirus species from 32 to 68, highlighting the growing need for effective management strategies, including traditional methods and advanced techniques like genome editing.
