NLR receptor is suggested as a component of plant nonhost resistance (NHR). However, the evolutionary process of how plants develop receptors for recognizing broad-spectrum pathogens is still elusive. Here, we observe that multiple RxLR effector families including 12 reported avirulence effectors of Phytophthora infestans are broadly conserved across the Phytophthora species.

Article Synopsis
  • A study compared the effectiveness and safety of direct oral anticoagulants (DOACs) with warfarin in patients suffering from antiphospholipid syndrome-associated venous thromboembolism (APS-VTE) in Korea.
  • Among 410 identified APS-VTE patients, both DOACs and warfarin showed similar rates of recurrent VTE and bleeding, but DOACs had a lower occurrence of arterial thrombosis and better overall outcomes.
  • The findings suggest that DOACs are at least as safe as warfarin for APS-VTE patients, with a notable advantage in reducing arterial thrombosis risk and composite adverse events.

The transgenic plant is a promising strategy for the production of highly valuable biotherapeutic proteins such as recombinant vaccines and antibodies. To achieve an efficient level of protein production, codon sequences and expression cassette elements need to be optimized. However, the systematical expression of recombinant proteins in plant biomass can generally be controlled for the production of therapeutic proteins after the generation of transgenic plants.

This study aimed to validate the new European Leukemia Net (ELN) 2022 criteria for genetic risk stratification in older adults with acute myeloid leukemia (AML) and to determine the most likely set of clusters of similar cytogenetic and mutation properties correlated with survival outcomes in three treatment groups: intensive chemotherapy (IC), hypomethylating agents (HMA) alone, and HMA plus venetoclax (HMA/VEN). The study included 279 patients (aged ≥60 years) who received IC (N=131), HMA (N=76), and HMA/VEN (N=72) between July 2017 and October 2021. No significant differences were observed in survival among the groups according to ELN 2022 risk stratification.

Plant nucleotide-binding domain leucine-rich-repeat receptor (NLR) confers disease resistance to various pathogens by recognizing effectors derived from the pathogen. Previous studies have shown that overexpression of the CC domain in several NLRs triggers cell death, implying that the CC domain plays an important role as a signaling module. However, how CC domain transduces immune signals remains largely unknown.

Pathogen effectors target diverse subcellular organelles to manipulate the plant immune system. Although the nucleolus has emerged as a stress marker and several effectors are localized in the nucleolus, the roles of nucleolar-targeted effectors remain elusive. In this study, we showed that Phytophthora infestans infection of Nicotiana benthamiana results in nucleolar inflation during the transition from the biotrophic to the necrotrophic phase.

Nonhost resistance (NHR) is a robust plant immune response against non-adapted pathogens. A number of nucleotide-binding leucine-rich repeat (NLR) proteins that recognize non-adapted pathogens have been identified, although the underlying molecular mechanisms driving robustness of NHR are still unknown. Here, we screened 57 effectors of the potato late blight pathogen Phytophthora infestans in nonhost pepper (Capsicum annuum) to identify avirulence effector candidates.

Pathogen effectors can suppress various plant immune responses, suggesting that they have multiple targets in the host. To understand the mechanisms underlying plasma membrane-associated and effector-mediated immunity, we screened the Phytophthora capsici RxLR cell death-inducer suppressing immune system (CRISIS). We found that the cell death induced by the CRISIS2 effector in Nicotiana benthamiana was inhibited by the irreversible plasma membrane H+-ATPase (PMA) activator fusicoccin.

Attempts to reduce the sugar content of carbonated drinks are ongoing. Reducing the sugar content while maintaining the sensory quality requires the development of an effective sensory test method that can measure a consumers' perceived sensory difference and preference of reformulated products against the reference product. The A-Not A with reminder (A-Not AR) method (sometimes called the reminder method) allows blind sensory tests of multiple test samples vs.

Elucidation of the genomic organizations of transgene insertion sites is essential for the genetic studies of transgenic plants. Herein, we establish an analysis pipeline that identifies the transgene insertion sites as well as the presence of vector backbones, through de novo genome assembly with high-throughput sequencing data in two transgenic soybean lines, AtYUCCA6-#5 and 35S-UGT72E3/2-#7. Sequencing data of approximately 28× and 29× genome coverages for each line generated by high-throughput sequencing were de novo assembled.

Article Synopsis
  • Plants have immune receptors called NLR proteins that can trigger cell death even without pathogen presence, often seen in pepper (Capsicum annuum) through a specific group known as ANLs (ancient and autonomous NLRs).
  • This study identified that a part of the NLRs, the coiled-coil (CC) domains, is essential for inducing cell death, which resembles the hypersensitive response to actual infections.
  • The research also indicates that these CC domains operate independently of certain helper proteins and are structurally conserved across several plant species, suggesting a broader evolutionary significance and potential for studying plant immunity mechanisms.

During the evolution of land plants from aquatic to terrestrial environments, their aerial surfaces were surrounded by cuticle composed of cutin and cuticular waxes to protect them from environmental stresses. Glycerol-3-phosphate acyltransferase (GPAT) harboring bifunctional sn-2 acyltransferase/phosphatase activity produces 2-monoacylglycerol, a precursor for cutin synthesis. Here, we report that bifunctional sn-2 GPATs play roles in cuticle biosynthesis and gametophore development of Physcomitrella patens.
