Paralogous LRR receptor kinases confer symbiosis specificity between arbuscular mycorrhizal and root nodule symbioses in Lotus japonicus

Zhiqiong Zheng, Min Cai, Jing Liu, Ning Zhou et autres

Arbuscular mycorrhizal (AM) and root nodule (RN) symbiosis play essential roles in plant nutrient acquisition and share a common symbiotic signal transduction pathway, yet they produce distinct developmental outcomes. Here, we identify arbuscular mycorrhiza-induced kinase 2 (AMK2), a leucine-rich repeat receptor-like kinase …

Nitrate-induced NLP1 SUMOylation regulates nitrate signaling and root nodulation

Jing Liu, Zhenpeng Luo, Jiang Wang, Jiahao Lin et autres

Nitrate serves both as an essential nutrient and a key signaling molecule that shapes plant growth. In legumes, high nitrate concentrations suppress symbiotic nitrogen fixation, a process mediated by MtNLP1 (NIN-like protein1). Although nitrate minimally affects NLP transcript levels, it strongly controls …

Autoactive MtDMI1 Reprogrammes Immunity and Development in Tomato via Ethylene Signalling

Haiyue Liu, Ji Xu, Fang Xie

ABSTRACT The Common Symbiosis Signalling Pathway (CSSP) underpins interactions between plants and microbes, yet its potential for crop improvement remains underexplored. Here, we investigated the gain‐of‐function mutant SPD1 ( MtDMI1 S760N ), which constitutively activates the symbiotic signalling pathway in Medicago truncatula …

Distinct domain regions of NIN and NLP1 mediate symbiotic and nitrate signalling in Medicago truncatula

Jiang Wang, Mengdi Fu, Zhenpeng Luo, Jing Liu et autres

Nodule Inception (NIN) and NIN-like protein 1 (NLP1), both belonging to the RWP-RK type transcription factors, play critical roles in plant development. Specifically, NIN is pivotal in facilitating root nodule symbiosis in nitrogen-starved conditions, while NLP1 coordinates nodulation in response to nitrate …

Loss of Lateral suppressor gene is associated with evolution of root nodule symbiosis in Leguminosae

Tengfei Liu, Zhi Xin Liu, J. H. Fan, Yaqin Yuan et autres

BACKGROUND: Root nodule symbiosis (RNS) is a fascinating evolutionary event. Given that limited genes conferring the evolution of RNS in Leguminosae have been functionally validated, the genetic basis of the evolution of RNS remains largely unknown. Identifying the genes involved in the …

Duplication and sub‐functionalization of flavonoid biosynthesis genes plays important role in Leguminosae root nodule symbiosis evolution

T.Q. Liu, Haiyue Liu, Wenfei Xian, Zhi Xin Liu et autres

-fixing agent in agricultural systems that exists mainly in Leguminosae, is one of the most attractive evolution events. However, the gene innovations underlying Leguminosae root nodule symbiosis (RNS) remain largely unknown. Here, we investigated the gene gain event in Leguminosae RNS evolution …

Soybean symbiotic-nodule zonation and cell differentiation are defined by NIN2 signaling and GH3-dependent auxin homeostasis

Tianli Tu, Zhen Gao, Linfang Li, Jiansheng Chen et autres

Symbiotic nodules comprise two classes, indeterminate and determinate, defined by the presence/absence of apical meristem and developmental zonation. Why meristem and zonation are absent from determinate nodules remains unclear. Here, we define cell types in developing soybean nodules, highlighting the undifferentiated infection …

GmNLP1 and GmNLP4 activate nitrate‐induced CLE peptides NIC1a/b to mediate nitrate‐regulated root nodulation

Mengdi Fu, Xiaolei Yao, Xiaolin Li, Jing Liu et autres

Symbiotic nitrogen fixation is an energy-intensive process, to maintain the balance between growth and nitrogen fixation, high concentrations of nitrate inhibit root nodulation. However, the precise mechanism underlying the nitrate inhibition of nodulation in soybean remains elusive. In this study, CRISPR-Cas9-mediated knockout …

RinRK1 enhances NF receptors accumulation in nanodomain-like structures at root-hair tip

Xiaolin Li, Zhiqiong Zheng, Jing Liu, J. Allan Downie et autres

Legume-rhizobia root-nodule symbioses involve the recognition of rhizobial Nod factor (NF) signals by NF receptors, triggering both nodule organogenesis and rhizobial infection. RinRK1 is induced by NF signaling and is essential for infection thread (IT) formation in Lotus japonicus. However, the precise …
