Iron (Fe) homeostasis is critical for plant growth, development, and stress responses. Fe levels are tightly controlled by intricate regulatory networks in which transcription factors (TFs) play a central role. A series of basic helix-loop-helix (bHLH) TFs have been shown to contribute homeostasis, but the layers beyond bHLH remain largely unclear. Here, we demonstrate that SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE (SPL) TF SlSPL-CNR negatively regulates Fe-deficiency responses tomato (Solanum...
Abstract Changing ambient temperature often impairs plant development and sexual reproduction, particularly pollen ontogenesis. However, mechanisms underlying cold stress-induced male sterility are not well understood. Here, we exposed Chinese cabbage (Brassica campestris) to different conditions during flowering demonstrated that the tetrad stage was most sensitive. After completion of at optimal conditions, transient stress still impacted auxin levels, starch lipid accumulation,...
Abstract Iron (Fe) distribution and reutilization are crucial for maintaining Fe homeostasis in plants. Here, we demonstrate that the tomato (Solanum lycopersicum) Colorless nonripening (Cnr) epimutant exhibits increased retention cell wall pectin due to an increase methylesterase (PME) activity. This ultimately leads deficiency responses even under Fe-sufficient conditions when compared wild type (WT). Whole-genome bisulfite sequencing revealed modifications wall-related genes, especially...
Deinococcus radiodurans (ex Raj et al. 1960) Brooks and Murray 1981 is well known for its efficient repair of various types physically or chemically induced DNA damage caused by ionizing ultraviolet radiation H2O2. RecG codes a helicase that to be involved in repairing oxidative other bacterium. In this work, we constructed DRrecG deletion mutant investigated possible role H2O2-induced damage. The results showed the resulted an obvious growth defect great decrease radioresistance D. gamma We...
Iron (Fe) is an essential micronutrient for all organisms, including plants, whose limited bioavailability restricts plant growth, yield, and nutritional quality. While the transcriptional regulation of responses to Fe deficiency have been extensively studied, contribution epigenetic modulations, such as DNA methylation, remains poorly understood. Here, we report that treatment with a methylase inhibitor repressed deficiency-induced in tomato (Solanum lycopersicum) roots, suggesting...
Abstract SENSITIVE TO PROTON RHIZOTOXICITY 1 (STOP1) is a core transcription factor that regulates the expression of aluminum (Al) resistance genes to manage Al toxicity in plants. However, genome-wide roles SlSTOP1 stress response tomato (Solanum lycopersicum) remain largely unknown. Here, we report crucial for tolerance tomato, as loss-of-function mutants displayed hypersensitivity stress. Aluminum had no effect on mRNA expression, but promoted accumulation protein nucleus. Through...
