Alternative splicing of a disease resistance gene maintains homeostasis between growth and immunity
Plant Science Research WeeklyPlant resistance genes encode proteins that trigger immune responses when they recognize pathogen effectors. Their activation must be carefully regulated, as overexpression of activation of R genes usually causes a decrease in growth rate. Here, Sun et al. investigated the role of alternative splicing…
Review: Root development and symbiosis: an epigenetic perspective
Plant Science Research WeeklyRoots do not grow in isolation but occupy a space inhabited by a variety of organisms. With certain fungi and bacteria, they form partnerships or symbiotic relationships that increase the plant’s nutrient uptake and assimilation. While the knowledge on the genetic programs required to establish these…
Harnessing the potential of soil microbial allies to combat Striga infection in sorghum roots
Plant Science Research WeeklyMicrobial neighbors of plants in the soil comprise of a vast array of bacteria and fungi, collectively known as the microbiome. This soil microbial community forms close associations with plants and regulates plant growth and development by inducing changes in the plant and soil metabolites. In this…
Review: Engineering plant–microbe communication for plant nutrient use efficiency
Plant Science Research WeeklyPlant nutrient use efficiency (NUE) has become a major concern in recent years as farmers and scientists strive to make agriculture more sustainable. To this end, the manipulation of plant-microbe interactions holds great potential. In this short review, Griffin et al. highlight recent findings, focusing…
Non-immunogenic bacterial epitopes mask recognition of their immunogenic counterparts
Plant Science Research WeeklyHost plants recognize diverse bacterial epitopes, known as microbe-associated molecular patterns (MAMPs), and respond with an immune reaction to control bacterial growth. However, most studies have focused on single bacterial epitopes, limiting our understanding of plant-bacteria interaction outcomes…
Leaf yellowing phenotype in rice, mediated by phytoplasma-secreted effector protein, attracts insect vectors
Plant Science Research WeeklyPhytoplasmas are bacterial pathogens that induce significant morphological changes in a host plant including prominent leaf yellowing. They are known to be transmitted by piercing-sucking insects or phloem-feeding arthropods. Phytoplasmas alter plant developmental process through specific effectors.…
Coordinated wound responses in a regenerative animal-algal holobiont
Plant Science Research WeeklyMany animals such as corals and sea slugs host photosynthetic symbionts. Several studies have investigated how the host and symbiont coordinate their activities. This new study by Sarfati et al. explores how symbiotic green algae and their animal host, the flattened-worm Convolutriloba longifissura,…
Spatial co-transcriptomics reveals discrete stages of the arbuscular mycorrhizal symbiosis
Plant Science Research WeeklyIn recent years, single-cell RNA sequencing (scRNA-seq) and single-nuclei RNA sequencing (snRNA-seq) techniques have revolutionized plant biology by enabling the identification of novel cell types, modeling developmental trajectories, and analyzing transcriptional activity at the cellular level. However,…
Review: The plant immune system: From discovery to deployment
Plant Science Research WeeklyA review of the past 50 years of plant immunity by Jones, Staskawicz, and Dangl? Yes please! I particularly enjoy historical perspectives of a discipline, as they frame conceptual breakthroughs with the benefit of hindsight. As the article lays out, understanding the plant immune system benefitted greatly…
