Chemosensory function of Varroa gnathosoma: transcriptomic and proteomic analyses.

Exp Appl Acarol

December 2024

Department of Entomology, Institute of Plant Protection, Agricultural Research Organization, the Volcani Center, Rishon LeZion, Israel.

In this study, we evaluated the role of the gnathosoma (mouthparts) in chemosensing of the most devastating honey bee parasite, Varroa destructor mite. Through transcriptomic analysis, we compared the expression of putative chemosensory genes between the body parts containing the main chemosensory organs (the forelegs), gnathosoma and the rest of the body devoid of these two body parts. Furthermore, we checked the presence of chemosensory-related transcripts in the proteome of the gnathosoma.

During our search for aphid-pathogenic viruses, a comovirus was isolated from wild asymptomatic (white mustard) plants harboring a dense population of aphids. The transmission-electron-microscopy visualization of purified virions revealed icosahedral particles. The virus was mechanically transmitted to plants belonging to , , and families, showing unique ringspot symptoms only on var.

Article Synopsis
  • Phosphate (P) is essential for plant growth, but its availability in soil can restrict development, making it important to understand how plants adapt to low P conditions.
  • This study utilizes genome-wide association studies (GWAS) on diverse tomato accessions to identify genetic factors associated with traits related to P uptake, measuring parameters like shoot height and root length under normal and low P conditions.
  • The research identified specific single nucleotide polymorphisms (SNPs) linked to key plant traits, offering insights into potential candidate genes that could be used in breeding programs to create P-efficient tomato varieties for sustainable agriculture.

Climate change is often associated with increasing vapour pressure deficit (VPD) and changes in soil moisture (SM). While atmospheric and soil drying often co-occur, their differential effects on plant functioning and productivity remain uncertain. We investigated the divergent effects and underlying mechanisms of soil and atmospheric drought based on continuous, in situ measurements of branch gas exchange with automated chambers in a mature semiarid Aleppo pine forest.

Institute of Evolution, University of Haifa, Mt. Carmel, Haifa 3498838, Israel; The Department of Evolutionary and Environmental Biology, University of Haifa, Mt. Carmel, Haifa 3498838, Israel. Electronic address:

Gene cloning in repeat-rich polyploid genomes remains challenging. Here, we describe a strategy for overcoming major bottlenecks in cloning of the powdery mildew resistance gene (R-gene) Pm69 derived from tetraploid wild emmer wheat. A conventional positional cloning approach was not effective owing to suppressed recombination.

This paper presents a protocol for the convenient and high-throughput isolation and enrichment of glandular capitate stalked and sessile trichomes from Cannabis sativa. The biosynthetic pathways for cannabinoid and volatile terpene metabolism are localized primarily in the Cannabis trichomes, and isolated trichomes are beneficial for transcriptome analysis. The existing protocols for isolating glandular trichomes for transcriptomic characterization are inconvenient and deliver compromised trichome heads and a relatively low amount of isolated trichomes.

Article Synopsis
  • Chromatin controls gene expression through epigenetic modifications, particularly focusing on histone H3, specifically lysine 27 (H3K27), which is modified by the Polycomb Repressive Complex 2 (PRC2) to regulate developmental genes.
  • Research using a non-modifiable version of H3K27 in Arabidopsis revealed severe developmental issues similar to PRC2 mutants, such as early flowering and increased callus formation.
  • The study uncovers new roles for H3K27 in determining plant cell functions and metabolic processes, indicating its significant impact on stem elongation and lignin composition.

Plants host diverse microbial communities, which undergo a complex interaction with each other. Plant-associated microbial communities provide various benefits to the host directly or indirectly, viz. nutrient acquisition, protection from pathogen invaders, mitigation from different biotic and abiotic stress.

Microalgae are microscopic photosynthetic organisms frequently found in fresh and marine water ecosystems. Various microalgal species have been considered a reservoir of diverse health-value products, including vitamins, proteins, lipids, and polysaccharides, and are broadly utilized as food and for the treatment of human ailments such as cancer, cardiovascular diseases, allergies, and immunodeficiency. Microalgae-derived carotenoids are the type of accessory pigment that possess light-absorbing potential and play a significant role in metabolic functions.

The hydraulic system of vascular plants and its integrity is essential for plant survival. To transport water under tension, the walls of xylem conduits must approximate rigid pipes. Against this expectation, conduit deformation has been reported in the leaves of a few species and hypothesized to function as a 'circuit breaker' against embolism.

Reactivity of Vitamin E as an Antioxidant in Red Meat and the Stomach Medium.

J Agric Food Chem

September 2022

Department of Food Science, ARO Volcani Center, Bet-Dagan 50250, Israel.

The stomach is a bioreactor and an important intersection of biochemical reactions that affect human health. Lipid peroxidation of meat in the stomach medium generates malondialdehyde (MDA), which is absorbed from the gut into human plasma and modifies low-density lipoprotein (LDL) to MDA-LDL. We found in the stomach medium (pH 3.

Department of Postharvest Science, A.R.O., Volcani Center, Bet Dagan 50250, Israel.

Plants interact with diverse microbial communities and share complex relationships with each other. The intimate association between microbes and their host mutually benefit each other and provide stability against various biotic and abiotic stresses to plants. Endophytes are heterogeneous groups of microbes that live inside the host tissue without showing any apparent sign of infection.

The nucleotide-binding site (NBS)-encoding gene is a major type of resistance (R) gene, and its diverse evolutionary patterns were analyzed in different angiosperm lineages. Until now, no comparative studies have been done on the NBS encoding genes in species. In this study, various numbers of NBS-encoding genes were identified across the whole genome of sweet potato () (#889), (#554), (#571), and (#757).

Although it is an integral part of global change, most of the research addressing the effects of climate change on forests have overlooked the role of environmental pollution. Similarly, most studies investigating the effects of air pollutants on forests have generally neglected the impacts of climate change. We review the current knowledge on combined air pollution and climate change effects on global forest ecosystems and identify several key research priorities as a roadmap for the future.
