Efficient metabolic regulation is key for parasite growth. Here, the authors report that Toxoplasma alters its AMPK phosphorylation during the lytic cycle, which reprograms parasite’s metabolism to ensure metabolic needs at different stages are met.

Mycoviruses are obligate parasites of fungi. Here, Hai et al. show that mycoviruses can induce hypovirulence in the fungus Sclerotinia, and plants infected by Sclerotinia facilitate the transmission of these mycoviruses, thereby helping the plants defend against Sclerotinia.

Southern corn rust (SCR) caused by Puccinia polysora is a major maize disease that can result in major yield loss. Here, the authors report the expression of a CC-NB-LRR type of R gene RppK results in SCR resistance in susceptible maize lines and it can recognize the effector AvrRppK produced by P. polysora.

Editing of a rice gene that has a role in phospholipid synthesis has endowed rice plants with broad-spectrum resistance to disease, including protection from common bacterial and fungal pathogens, without decreasing the yield.

Leukemia inhibitory factor receptor (LIFR) is frequently downregulated in liver cancer. Here the authors show that loss of LIFR promotes liver tumorigenesis and confers resistance to drug-induced ferroptosis through NF-κB-mediated upregulation of iron-sequestering cytokine LCN2.

This study showed that the type III effector NopL can interact with the Nod factor receptor GmNFR5, and the existence of NopL can promote GmREM1 interacts with GmNFR5, which demonstrates a signaling pathway underlying the symbiosis establishment in soybean.

The occurrence and consequences of polyploidization in clonally reproducing animals is unclear. Here, the authors generate 4 polyploid Meloidogyne genomes, identifying a telomeric element, resolving genome structures and extensive chromosome fusion events, and revealing origin patterns.

This study presents an advanced ChIP-seq method, provides a valuable epigenomics resource for 14 economically important plant organs and reveals histone modification landscape dynamics and functions during rapeseed seed dormancy and germination.

De novo genome assembly and analyses of 12 maize FILs provide insights into genomic and phenotypic differentiation of various heterotic groups and the molecular basis of heterosis in maize.

Xu et al. showed that a histone acetyltransferase interacts with an acetyl-CoA synthetic enzyme for histone acetylation to stimulate gene expression and endosperm cell division, pointing to a mechanism coupling energy metabolism to epigenetics.

GY3 encodes a LOG-like protein that acts as a 5′-ribonucleotide phosphohydrolase in cytokinin synthesis. A Gypsy solo-LTR insertion downregulates GY3 expression and shows the potential to enhance grain yield in rice.

Fluorescence in situ hybridization (FISH) methods with high sensitivity are needed. Here the authors develop multiplex πFISH rainbow to detect a range of biomolecules; they also combine this with the hybridization chain reaction to develop πFISH+ technology for short nucleic acid fragment detection.

Genome sequencing and haplotype assembly of two cyprinid teleosts, a sexual tetraploid and an unisexual hexaploid, reveal insights into the evolutionary mechanisms underpinning the reproductive success of unisexual polyploid vertebrates.

Grain protein content (GPC) contributes to the nutritional quality of cereals. Here, the authors show that the OsAAP6 quantitative trait locus in rice controls GPC by regulating the synthesis and accumulation of several grain storage proteins and starch.

Unilateral cross incompatibility (UCI) is a type of prezygotic reproductive isolation, which is associated with multiple loci in maize. Here, the authors use genetic analysis to separate the Ga1 locus into two functional components and identify seven linked genes encoding three types of proteins.

Cytokinin is essential for regulation of nodulation. Here, the authors identified a B-type response regulator GmRR11d that governs a transcriptional program associated with nodulation and cytokinin activation essential for systemic regulation of nodulation.

Insect salivary protein (BISP) targets OsRLCK185 to suppress defence in susceptible plants, whereas in resistant plants BISP binds BPH14 to activate host plant resistance. To restore cellular homeostasis, the resistance mechanism is fine-tuned by selective autophagy.

Histone variant macroH2A1 represses gene expression in heterochromatin. New data show that it can also stimulate transcription by cooperating with PARP-1 to promote CBP-mediated H2B acetylation and that this regulatory function is lost in cancer cells.

An improved reference genome of sweet orange and newly sequenced genomes of its somatic mutants uncover the global pattern of somatic variations, the diversification and dispersal history of sweet orange and candidate genes controlling fruit taste and flavour.

The authors integrate spatial (Stereo-seq) and single-cell transcriptomes of the developing maize ear to produce an atlas of maize ear cells and their developmental trajectories. They also identify a pair of transcription factors involved in inflorescence development.

Glucocorticoids and glucocorticoid receptor (GR) signalling can suppress anti-tumour immunity. Here the authors show that GR activates PD-L1 expression and represses MHC-I expression in pancreatic cancer cells, while GR inhibition enhances anti-tumour immunity and sensitises the cancer cells to immunotherapy.

This study reports the striking discovery that a water-impermeable barrier known as suberin lamellae was first evolved in the common ancestor of seed plants and contributed to their evolutionary success.

An NMR study on K113-ubiquitinated BAK complex reveals that the conjugated ubiquitin subunit binds to the canonical hydrophobic groove of BAK, which prevents the binding of prodeath BH3 activators and impairs BH3-induced BAK apoptotic activity.

Measuring gene expression in individual cells is crucial for understanding the gene regulatory network controlling human embryonic development. Single-cell RNA sequencing (RNA-Seq) analysis of 124 individual cells from human preimplantation embryos and embryonic stem cells (hESCs) now provides a comprehensive framework of the transcriptome landscapes of human early embryos and hESCs.

TnpB protein from a thermophilic archaea has collateral ssDNA cleavage activity activated by high temperature that has been employed in developing a new fast and sensitive TnpB-based nucleic acid detection tool (TESD).

This protocol describes how to carry out the sucrose preference test (SPT) in a standardized way to reduce data variability. The SPT is a widely used behavioral assay to monitor depression-related behavior in rodents.
