New insight into Ca -permeable channel in plant immunity.

Calcium ions (Ca ) are crucial intracellular second messengers in eukaryotic cells. Upon pathogen perception, plants generate a transient and rapid increase in cytoplasmic Ca levels, which is subsequently decoded by Ca sensors and effectors to activate downstream immune responses. The elevation of cytosolic Ca is commonly attributed to Ca influx mediated by plasma membrane-localized Ca -permeable channels.

Interkingdom Hormonal Regulations between Plants and Animals Provide New Insight into Food Safety.

Food safety has become an attractive topic among consumers. Raw material production for food is also a focus of social attention. As hormones are widely used in agriculture and human disease control, consumers' concerns about the safety of hormone agents have never disappeared.

WeiTsing, a pericycle-expressed ion channel, safeguards the stele to confer clubroot resistance.

Plant roots encounter numerous pathogenic microbes that often cause devastating diseases. One such pathogen, Plasmodiophora brassicae (Pb), causes clubroot disease and severe yield losses on cruciferous crops worldwide. Here, we report the isolation and characterization of WeiTsing (WTS), a broad-spectrum clubroot resistance gene from Arabidopsis.

SHOU4/4L link cell wall cellulose synthesis to pattern-triggered immunity.

Pattern recognition receptors (PRRs) are plasma membrane-localised proteins that sense molecular patterns to initiate pattern-triggered immunity (PTI). Receptor-like cytoplasmic kinases (RLCKs) function downstream of PRRs to propagate signal transduction via the phosphorylation of substrate proteins. The identification and characterisation of RLCK-regulated substrate proteins are critical for our understanding of plant immunity.

A surface-receptor-coupled G protein regulates plant immunity through nuclear protein kinases.

Plants employ cell-surface-localized pattern recognition receptors (PRRs) to recognize immunogenic patterns and activate defenses. How these receptors regulate immune signaling in the nucleus is not well understood. Our previous studies showed that BIK1, a central kinase associated with PRRs, phosphorylates a plant-specific Gα protein called extra-large G protein 2 (XLG2) to positively regulate immunity.

Responses of greenhouse gas emissions to residue returning in China's croplands and influential factors: A meta-analysis.

Climate change is a global issue threatening agricultural production and human survival. However, agriculture sector is a major source of global greenhouse gases (GHGs), especially CH and NO. Crop residue returning (RR) is an efficient practice to sequestrate soil carbon and increase crop yields.
