🧬 🌱 VIEWPOINT: 'Transposable element-driven evolution of herbicide resistance in plants' – Madhab Kumar Sen et al. doi.org/10.1093/jxb/...

#PlantScience 🧪
Diagramatic illustration of the molecular and biochemical mechanisms plants use to develop herbicide resistance. Mutations in herbicide target proteins prevent effective binding, while gene amplification boosts target protein expression, allowing plants to survive. Epigenetic modifications, such as DNA methylation, silence genes related to herbicide sensitivity or maintain genes promoting tolerance. Herbicide detoxification occurs in three phases: phase I modifies the herbicide (e.g. hydroxylation), phase II conjugates it with sugars, and phase III transports the detoxified molecules out of the cell. These processes enable resistant plants to survive and neutralize herbicides.

I'm enjoying reading this paper from @newphyt.bsky.social:

Vascular tissue – boon or bane? How pathogens usurp long-distance transport in plants and the defence mechanisms deployed to counteract them

Clear, accessible, & introduced me to new ideas that I hadn't thought of before #PlantScience
Vascular tissue as a target for biotic factors. Under optimal conditions, the phloem and xylem coordinate numerous trophic relations within the plant. This situation changes upon infection by pathogens that can exploit vascular connections to redirect nutrients or to colonise the plant systemically. On the left panel, a healthy plant is depicted with a well-functioning vascular system which photosynthesises efficiently and transpires adequately. Water (H2O) gets taken up from the roots by xylem and the transpiration from aerial tissues of the plant creates a strong negative pressure facilitating distribution over long distance (depicted by blue arrows). Sucrose produced in source leaves is distributed via phloem to physiological sinks such as young leaves, roots and underground storage organs like tubers (red arrows). On the right panel, when the plant is under attack, these processes are compromised as the pathogens and newly arising physiological sinks impose high demands on the plant for nutrition and water. Pathogens use different ways to colonise and gain entry to the vascular system, from the top via stomata and other openings. Plant roots are also in constant contact with soil-borne pathogens, which are able to colonise the conductive tissue. Numerous insects including herbivorous like grasshoppers or sap drinkers like aphids or psyllids are natural vectors of vascular pathogens and are responsible for the spread of the majority of phloem-specific disease factors. Some of the uninvited guests (viruses, bacteria, protists, nematodes and galling insects) can manipulate and exploit plant vascular system and stimulate the development of galls or tumours to support nutrient redirection. Potential pathogen entry sites are depicted with black arrows. Salient features of vascular transport through plant conductive tissues – xylem and phloem. Local and global distribution of water, mineral nutrients, carbohydrates, phytohormones, and primary and secondary metabolites, plays a crucial role in coordinating overall plant growth and nutrition. Lateral fluxes between these tissues help in reshuffling and modulating nutrient flow dynamically. The internal environment of the xylem is characterised by a huge negative pressure generated as the result of transpiration pull. This presents unfavourable and hostile conditions to invading pathogens. Phloem, on the contrary, represents a nutrient-rich and secure cellular environment, which is difficult to access for pathogens but readily habitable. Based on its function, phloem at different physiological source and sink regions can be divided into collection, transport and release phloem. Transporters such as bidirectional SUGARS WILL EVENTUALLY BE EXPORTED TRANSPORTERS (SWEETs) and unidirectional SUCs help in regulating carbohydrate transport across phloem parenchyma (PPs) and companion cells (CCs), which is then loaded into sieve elements (SEs). During pathogen infection, almost all aspects of vascular transport are manipulated by different microbes to suit their lifestyle and metabolic requirements (marked by lightning arrows in pink).
