In Figure 4B, the fluorescence images for TaPUB1-RNAi 5 were incorrect. The error occurred due to misplacement of images during assembly of the composite figure. The authors reviewed the original photographs and prepared corrected images. Both the original and revised versions of Figure 4B are shown below. The correction does not affect the description of the data, or conclusions drawn in the text.

We apologize for this error.

Grapes have been a part of human civilization throughout our history. Cultivated grapes were domesticated from wild grapes and the cover illustrates the domestication process: wild grapes on the left contrast with cultivated grapes on the right, mitochondria symbolize the cytoplasmic component, a DNA double helix bridges genetic information exchange, and the nucleus within the grape fruits represents the nuclear genome. Together, these images highlight the continuous cytonuclear interactions that have shaped grape domestication. This cover features the study by Hou et al. (page: 2686–2703), who uncovered the potential role of cytoplasmic genomes in domestication, offering new insights into grape evolution and crop improvement.

Chitin and its deacetylated derivative chitosan are the major components of fungal cell walls and are recognized by plant pattern-recognition receptors (PRRs) as pathogen-associated molecular patterns that induce innate immunity. Recognition of chitin oligosaccharide (CTOS) in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa) requires the membrane-localized lysin-motif (LysM)-domain-containing receptors AtLYK5 and OsCEBiP, respectively. However, the mechanism underlying chitosan oligosaccharide (CSOS)-induced plant immunity remains unclear. In this study, we determined that CTOS and CSOS trigger immune responses and boost disease resistance in soybean (Glycine max) through the LysM-domain-containing protein GmNRF5a and its co-receptor GmCERK1. Surprisingly, both GmNFR5a and GmCERK1 bind directly to CTOS and CSOS, with distinct binding sites. The receptor-like kinase GmCAK1 acts downstream of GmCERK1 and is essential for CTOS/CSOS-mediated immune activation. Overall, these findings uncovered how soybean plants respond to CSOS and initiate immune signaling, demonstrating that soybean exploits shared immune sectors to transduce immune signals triggered by CTOS/CSOS, paving the way for the development of disease-resistant crops with broad-spectrum resistance.

Dissecting quantitative traits into Mendelian factors is a great challenge in genetics. Apple fruit storability is a complex trait controlled by multi-genes with unequal effects. We previously identified 62 quantitative trait loci (QTLs) associated with apple fruit storability and genomics-assisted prediction (GAP) models were trained using 56 QTL-based markers. Here, three candidate genes, MdNAC83, MdBPM2, and MdRGLG3, were screened from the regions of QTLs with large G' value and large genetic effects. Both a 216-bp deletion and an SNP934 T/C at the promoter of MdNAC83 were associated with higher MdNAC83 expression but an SNP388 G/A at the coding region significantly reduced the activity to activate the expression of the target genes MdACO1, MdMANA3, and MdXTH28. MdBPM2 and MdRGLG3 participated in the ubiquitination of MdNAC83. SNP657 T/A of MdBPM2 and SNP167 C/G of MdRGLG3 caused a reduction in the activity to ubiquitinate MdNAC83. By the addition of functional markers to the GenoBaits SNP array, the prediction accuracy of the updated GAP models increased to 0.7723/0.6231 and 0.5639/0.5345 for flesh firmness/crispness at harvest and flesh firmness/crispness retainability, respectively. The variation network involving eight simple Mendelian variations in six genes helps to gain insight into the molecular quantitative genetics, to improve breeding strategy, and to provide targets for future genome editing.

Gene scarcity and resistance breakdown limit the utility of plant NLRs. Findings in Nature by Wang et al. (2025) describe a bioengineering strategy using N-terminal blocking peptides to achieve tunable NLR activation, providing durable, broad-spectrum resistance to potyviruses in plants.

Sorghum (Sorghum bicolor (L.) Moench) is a climate-resilient C₄ cereal and a vital pillar of food and feed security in arid and semi-arid regions worldwide. In China, the development and widespread adoption of hybrid sorghum breeding have revolutionized the crop's productivity, playing a transformative role in enhancing both yield and quality. The success of hybrid sorghum, particularly through the utilization of cytoplasmic male-sterility (CMS) systems, has marked a milestone in agricultural innovation, enabling the large-scale production of high-performing hybrids. The implementation of dwarf breeding and the continuous renewals of sorghum hybrid varieties have been pivotal in driving these improvements. As we commemorate the 60th anniversary of the promotion and application of three-line hybrid sorghum, we recognize the groundbreaking contributions of Chinese researchers in advancing sorghum breeding science. This review highlights key scientific breakthroughs and systematically summarizes the evolution of sorghum breeding in China. By reflecting on both past achievements and prospective opportunities, we aim to inform strategies that will sustain and enhance sorghum's contribution to China's agricultural resilience and global food security.

Cold induces degradation of Aux/IAA proteins through the ubiquitin-proteasome pathway, releasing AUXIN RESPONSE FACTOR7 (ARF7) and ARF19 from Aux/IAA-mediated repression, leading to activation of CYTOKININ RESPONSE FACTOR 3 (CRF3) expression under cold stress. This study reveals a regulatory mechanism integrating cold signaling and auxin response in the control of CRF3 expression.
