Idiosyncratic and dose-dependent epistasis drives variation in tomato fruit size

Science, Journal Year: 2023, Volume and Issue: 382(6668), P. 315 - 320

Published: Oct. 19, 2023

Epistasis between genes is traditionally studied with mutations that eliminate protein activity, but most natural genetic variation in cis-regulatory DNA and influences gene expression function quantitatively. In this study, we used engineered alleles a plant stem-cell circuit to systematically evaluate epistatic relationships controlling tomato fruit size. Combining promoter allelic series two other loci, collected over 30,000 phenotypic data points from 46 genotypes quantify how allele strength transforms epistasis. We revealed saturating dose-dependent relationship also allele-specific idiosyncratic interactions, including driving step change size during domestication. Our approach findings expose an underexplored dimension of epistasis, which diversity within regulatory networks elicits nonlinear, unpredictable interactions shape phenotypes.

Published: April 30, 2024

Cytokinins are mobile phytohormones that regulate plant growth, development, and environmental adaptability. The major cytokinin species include isopentenyl adenine (iP), trans-zeatin (tZ), cis-zeatin (cZ), dihydrozeatin (DZ). spatial distributions of different in organelles, cells, tissues, organs primarily shaped by biosynthesis via isopentenyltransferases (IPT), cytochrome P450 monooxygenase, 5'-ribonucleotide phosphohydrolase conjugation or catabolism glycosyltransferase oxidase/dehydrogenase. bind to histidine receptor kinases the endoplasmic reticulum plasma membrane relay signals response regulators nucleus shuttle proteins known as phosphotransfer proteins. movements cytokinins from sites signal perception usually require long-distance, intercellular, intracellular transport. In past decade, ATP-binding cassette (ABC) transporters, purine permeases (PUP), AZA-GUANINE RESISTANT (AZG) equilibrative nucleoside transporters (ENT), Sugars Will Eventually Be Exported (SWEET) have been characterized involved transport processes.

Heat Stress and Plant–Biotic Interactions: Advances and Perspectives

Plants, Journal Year: 2024, Volume and Issue: 13(15), P. 2022 - 2022

Published: July 23, 2024

Climate change presents numerous challenges for agriculture, including frequent events of plant abiotic stresses such as elevated temperatures that lead to heat stress (HS). As the primary driving factor climate change, HS threatens global food security and biodiversity. In recent years, have negatively impacted physiology, reducing plant's ability maintain disease resistance resulting in lower crop yields. Plants must adapt their priorities toward defense mechanisms tolerate challenging environments. Furthermore, selective breeding long-term domestication higher yields made varieties vulnerable multiple stressors, making them more susceptible events. Studies on predict concurrent biotic will become severe future, potentially occurring simultaneously or sequentially. While most studies focused singular effects systems examine how plants respond specific stresses, simultaneous occurrence pose a growing threat agricultural productivity. Few explored interactions between plant-biotic interactions. Here, we aim shed light physiological molecular (bacteria, fungi, oomycetes, nematodes, insect pests, pollinators, weedy species, parasitic plants), well combined impact growth We also advances designing developing various strategies address multi-stress scenarios related factors.

Molecular Plant Pathology, Journal Year: 2025, Volume and Issue: 26(1)

Published: Jan. 1, 2025

ABSTRACT In the coevolutionary process between plant pathogens and hosts, pathogen effectors, primarily proteinaceous, engage in interactions with host proteins, such as transcription factors (TFs), during infection process. This review delves into intricate interplay TFs a key aspect prolonged complex battle plants pathogens. Effectors strategically manipulate using diverse tactics. These include modulating activity of TFs, influencing their incorporation multimeric complexes, directly changing TF expression levels, promoting degradation via ubiquitin‐proteasome system, inducing subcellular relocalization. The systematically presents documented interactions, elucidating mechanisms profound impact on host–pathogen dynamics. It emphasises central role defence investigates convergent evolution effectors targeting TFs.
