On the cover: Pathogens and their hosts are engaged in an ever-evolving arms race. Host pattern-recognition receptors detect invading fungi and recruit adaptor proteins to initiate a signaling cascade that ultimately triggers immune responses. In maize, the plasma-membrane-localized receptor ZmWAK recognizes an unknown signature from the fungal pathogen Sporisorium reilianum and relays the phosphorylation signal to the cytoplastic kinase ZmSnRK1α2, thereby facilitating its translocation into the nucleus for promoting the degradation of ZmWRKY53. The reduced accumulation of ZmWRKY53, in turn, causes the downregulated expression of transmembrane transporter genes, thereby restricting nutrient acquisition by Sporisorium reilianum in the apoplasts. Therefore, the ZmWAK-SnRK1α2-WRKY53 signaling module underlies quantitative resistance to head smut disease in maize. The cover portrays this host-pathogen conflict with a personified depiction, showing the soldiers in battle defending their supplies with a strategic counterattack against the enemies.

中国农业大学小麦研究中心研究建立了粗山羊草三个主要进化支的系统发生关系，并推测L3可能是最古老的进化支。研究在群体水平系统鉴定了普通小麦中粗山羊草来源的渐渗片段，并发现普通小麦D基因组中的遗传多态性主要来自新生突变（novel mutation）的贡献（51.4%）。该研究建立了Ae. tauschii种群和小麦D基因组的起源模型，解析了普通小麦D基因组遗传多态性形成的演化规律，丰富了对多倍体小麦的起源和演化的认识，也为拓宽D基因组的遗传基础和育种改良奠定了理论基础。

中国科学院亚热带农业生态研究所陈彩艳团队研究克隆了稻米镉积累调控的QTL基因Cd-safe 1（OsCS1）， 发现其编码OsMTP11转运蛋白，主要在叶韧皮部薄壁细胞中表达，通过内膜系统，将细胞质中的镉转运到液泡中隔离起来，从而阻滞镉从叶向籽粒转运。OsCS1的表达受转录因子OsIRO2的调控，OsIRO2通过结合OsCS1启动子的G-box基序，驱动其表达。多数籼稻的OsCS1等位有2个拷贝的G-box基序，而多数粳稻中只有1个G-box基序，因此，籼稻中OsCS1表达量高，而粳稻中OsCS1表达量低。在籼粳杂交后代中，保留籼稻的OsCS1等位基因能将更多的镉滞留在叶片中，降低籽粒镉含量。
