A key to achieve the goals put forward in UN's 2030 Agenda for Sustainable Development, it will need transformative change our agrifood systems. We must mount global challenge food security a sustainable manner context of climate change, population growth, urbanization, and depletion natural resources. Rice is one major staple cereal crops that has contributed, contributing, still contribute security. To date, rice yield held pace with increasing demands, due advances both fundamental biological studies, as well genomic molecular breeding practices. However, future production depends largely on planting resilient cultivars can acclimate adapt changing environmental conditions. This Special Issue highlight reviews original research articles exciting growing field rice-environment interactions could benefit breeding. also outline open questions propose directions 2050 research, calling more attentions develop environment-resilient especially hybrid rice, upland perennial rice.

Unveiling Methods to Stimulate Plant Resistance against Pathogens

Frontiers in Bioscience-Landmark, Journal Year: 2024, Volume and Issue: 29(5)

Published: May 14, 2024

Plant diseases caused by pathogens pose significant threats to agricultural productivity and food security worldwide. The traditional approach of relying on chemical pesticides for disease management has proven be unsustainable, emphasizing the urgent need sustainable environmentally friendly alternatives. One promising strategy is enhance plant resistance against through various methods. This review aims unveil explore effective methods stimulating resistance, transforming vulnerable plants into vigilant defenders pathogens. We discuss both conventional innovative approaches, including genetic engineering, induced systemic (ISR), priming, use natural compounds. Furthermore, we analyze underlying mechanisms involved in these methods, highlighting their potential advantages limitations. Through an understanding scientists agronomists can develop novel strategies combat effectively while minimizing environmental impact. Ultimately, this research offers valuable insights harnessing plant’s innate defense paves way practices agriculture.

A Sugarcane Smut Fungus Effector Hijacks Plant Vacuolar Sorting Receptor‐Mediated Trafficking to Evade Host Immune Detection

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

ABSTRACT The smut fungus Sporisorium scitamineum is a major pathogen in sugarcane, causing significant agricultural losses worldwide. However, the molecular mechanisms by which its effectors facilitate infection and evade host immunity remain largely unclear. In this study, we identified sugarcane vacuolar sorting receptor 1 gene ( ScVSR1 ), whose expression negatively correlate with several putative S. effector genes co‐expression network. Overexpression of Arabidopsis thaliana reduced resistance to fungal powdery mildew pathogen, indicating negative role plant defence. Among co‐expressed effectors, SsPE15, secreted cerato‐platanin‐like protein (CPP), physically interacts sorted into prevacuolar compartment (PVC) interacting cells. Deletion SsPE15 enhanced virulence, suggesting that acts as an immune elicitor. Furthermore, C‐terminal domain containing VSR signal, was found vesicular location. Notably, fusing bacterial AvrRpt2 significantly AvrRpt2‐triggered programmed cell death , process partially dependent on AtVSR1 AtVSR2. These findings reveal evasion strategy hijacks host's trafficking system avoid detection.

OsWRKY26 negatively regulates bacterial blight resistance by suppressing OsXa39 expression

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 9, 2025

Plants are susceptible to infection by various pathogens with high epidemic potential. Xanthomonas oryzae pv. (Xoo) causes bacterial blight in rice, one of the most significant diseases both temperate and tropical regions. In this study, we report identification characterization OsWRKY26, a sucrose-inducible transcription factor, that plays role plant defense responses following Xoo infection. We found mutant plants defective OsWRKY26 showed enhanced response specifically Xoo, indicating factor acts as negative regulator. contrast, did not exhibit higher resistance compared wild-type (WT) when infected rice blast fungal pathogen Magnaporthe oryzae. Transcriptomic analysis WT revealed several genes were upregulated mutants. Of these, selected OsXa39 for further analysis. Transient expression experiments protoplasts repressed Luciferase reporter gene driven promoter. Chromatin immunoprecipitation binds directly promoter region OsXa39. These findings suggest negatively regulates during repressing well other pathogen-related such OsXa47, OsBBR1, OsRSR1, OsPR1a, OsPR1-11, OsPR2, OsPR4c.
