Karrikins (KARs) are a class of molecules that are hypothesized to mimic an undiscovered plant hormone KL (KAI2 Ligand). The signaling cascade triggered by KAR/KL is initiated by the α/β-hydrolase, KAI2, and can regulate several traits like germination, stress tolerance, and others. KAI2 is related to the DWARF14 (D14) receptor involved in strigolactone signaling. KAI2 […]
A new paper by Sun et al. demonstrates a pathway through which drought tolerance in Arabidopsis is influenced by soil microbiota. Using transcriptomic and metabolomic analyses, Sun et al. identified a strain of Rhodanobacter that is recruited to the rhizosphere of drought-stressed plants and can help them mitigate drought stress. The authors found that Rhodanobacter […]
Plant parasitic nematodes such as root-knot nematodes (RKNs) are thought to use chemical cues from the plant to locate their favorable hosts. These chemical cues can code for host specificity and can drive the attraction or repulsion of nematodes. Recently, Wu et al. investigated the role of benzoxazinoids (BXs) in shaping chemoattractant cues for RKNs. […]
