Summary: Exposure to high iron enhances resistance to Magnaporthe oryzae infection in rice plants, possibly through upregulating defense-related genes and increasing production of phytoalexins. The infection also modulates the expression of genes involved in iron homeostasis. Iron and reactive oxygen species colocalize at infection sites. Understanding the crosstalk between iron signaling and immune signaling holds great potential for improving blast resistance in rice.

Summary: In this study, a new method was used to fabricate zinc oxide nanoparticles (ZnONPs) by mixing alkalescent nucleoside antibiotics with zinc hexanitrate. The alkalescent nucleoside AN03 was separated and purified from Streptomyces koyanogensis using macroporous resin and column chromatography. The ZnONPs were characterized and showed strong inhibitory effects against Magnaporthe grisea, causing breakage in hyphae and damage to the cells. Greenhouse experiments demonstrated that ZnONPs could control rice blast disease by 98% and promote rice plant growth. This study suggests that ZnONPs could be a potent biocontrol agent in rice blast disease management.

Summary: The broad-spectrum resistance gene Pi54 in rice confers resistance against multiple isolates of Magnaporthe oryzae, with a variety of miRNAs identified to play a role in balancing the interaction between different defense response genes during Pi54 mediated resistance in the rice line Taipei309(Pi54). Additionally, the study suggests that the Pi54 gene mediated blast resistance in rice is influenced by multiple microRNAs regulating the immunity pathways, resulting in an incompatible host-pathogen interaction.

Summary: This study uncovers a novel mechanism whereby the GSK2-OsDLA-OsWRKY53 module coordinates blast resistance and plant architecture via BR signalling in rice. The GRAS transcription factor OsDLA interacts with the negative regulator GSK2 to regulate BR signaling pathway, and also interacts with the WRKY transcription factor OsWRKY53, contributing to blast resistance and plant architecture.

Summary: The study confirmed that OsOXO2, OsOXO3 and OsOXO4 genes play crucial roles in panicle blast resistance in rice by regulating H2O2 accumulation and expression levels of PR genes. The resistance mediated by these genes is associated with the activation of JA and ABA signaling pathways, while suppressing the SA signaling pathway.

Summary: The study highlights the importance of rapid, high-amplitude transcriptional reprogramming in rice defense against blast fungus, with ribosome- and protein translation-related genes being significantly enriched among differentially expressed genes at 12 hpi in both susceptible and resistant cultivars. A core set of genes involved in response to both biotic and abiotic stress was identified, including metallothionein genes positively regulating rice resistance and a peroxidase gene negatively regulating it. This study provides novel insights into transcriptional reprogramming and serves as a valuable resource for functional studies on rice immune signaling components in resistance to blast disease.

Summary: In this study, the researchers characterized the interaction of OsWRKY62 and OsWRKY76 with importins, OsIM alpha 1a and OsIM alpha 1b, for nuclear translocation. They found that OsWRKY62.1 has a nuclear localization signal (NLS) and a nuclear export signal (NES), and these signals are responsible for the translocation of OsWRKY62.1 to the nucleus. The researchers also discovered that OsIM alpha 1a and OsIM alpha 1b enhance resistance to M. oryzae, while their knockout mutants decrease resistance to the pathogen.

Summary: Rice is a staple food for many people worldwide, but its yield is threatened by biotic stresses such as rice blast caused by Magnaporthe oryzae. Developing resistant varieties is an effective approach to control this devastating disease. Researchers have identified several resistance genes and non-pathogenic genes, which aid breeders in developing resistant varieties and pathologists in monitoring pathogenic isolates.

Summary: The enrichment of soil phosphorus (P) due to the increased use of P fertilizer in crop production has led to eutrophication and economic consequences. Monitoring and managing soil P reactions is crucial for sustainable soil P management. This study aimed to characterize P sorption and desorption capacities of different soils and determine the distribution of added P among various P pools. The results showed that soil pH and exchangeable aluminum were correlated with P sorption capacity and desorption. During incubation, a portion of the added P became non-extractable, while another portion became more soluble.

Summary: Natural and man-made ecosystems worldwide are susceptible to flooding, which causes environmental stress and leads to significant crop losses. Research on rice adaptation and tolerance to flooding/submergence has made considerable progress in the past two decades. Marker-assisted selection breeding approach using Sub1 QTL has been developed to improve flooding-tolerant rice varieties. However, gene pyramiding techniques need to be applied to develop flood-resilient rice varieties for different types of flooding stresses. This review provides an update on the molecular mechanisms, metabolic adaptations, and genetic factors governing rice flooding tolerance.

Summary: This study aimed to introduce marker-assisted backcross breeding (MABB)-mediated resistance genes against bacterial leaf blight (BLB) pathogens. Four Xoo resistance genes, xa21, xa13, xa5, and Xa4, were successfully introgressed into the high-yielding Malaysian MR297 lineage from the IRBB60 lineage using functional linked markers and SSR markers. The proportion of recurrent parent genome recovery (RPGR) at BC1F1, BC2F1, and BC2F2 was 81.94%, 92.30%, and 95.04%, respectively. Incorporating the four BLB resistance genes into the newly created lines would provide long-lasting and comprehensive protection against BLB. Therefore, MABB is a faster approach to introduce resistance genes compared to conventional breeding. All tested lines exhibited significant resistance to BLB, with three lines showing very high levels of resistance. It is recommended to use these new lines for commercially viable rice varieties.

Summary: Understanding how pea accessions respond to high temperatures is important for breeding heat-tolerant pea varieties. This study examined 94 pea accessions grown in Malaysia and Indonesia and found that heat stress significantly reduced grain yield in Malaysia but not in Indonesia. Certain traits, such as the number of seeds per pod, were positively correlated with yield in both countries. Accessions B32, A19, G76, A11, and D44 were identified as potentially promising for high-temperature conditions.

Summary: Understanding heterosis and combining ability is crucial for developing hybrid kenaf. A diallel scheme using Griffing diallel analysis technique was conducted on nine parental genotypes of kenaf, producing 36 F-1 combinations. The results showed significant variability for most traits, with predominance of additive gene for traits related to plant height, stem diameter, flowering time, number of pods, number of seeds and seed weight. High heritability was observed for seed number, while moderate heritability was observed for flowering time and seed weight. The hybrids H3, H4, H9, H11, H23, H29 and H35 showed high heterotic for fiber and seed yield.

Summary: Despite the economic contributions of the oil palm industry to Malaysia, it is facing severe threats from basal stem rot disease. A greenhouse study was conducted to evaluate the potential of biological control agents as treatments for this disease. The results showed that treatment with Trichoderma asperellum (UPM16) had the highest disease reduction, while Bacillus cereus (UPM15) showed the highest readings in all assays for Ganoderma-infected seedlings. The combination treatment with B. cereus and T. asperellum (BT) resulted in the detection of the most abundant metabolite, 4-2-aminoethyl-phenol.
