Guercio et al., combine structural biology, biochemistry, and plant biology to reveal the dual functions of evolutionarily diverged Pisum KAI2A and KAI2B as both receptors and enzymes with distinct ligand selectivity, and propose adaptive sensitivity

Strigolactones (SLs) are well known for their role in repressing shoot branching. In pea, increased transcript levels of SL biosynthesis genes are observed in stems of highly branched SL deficient (ramosus1 (rms1) and rms5) and SL response (rms3 and

KAI2 are plant α/β hydrolase receptors, which perceive smoke-derived butenolide signals (karrikins) and putative endogenous, yet unidentified phytohormones (KAI2-ligands, KLs). The number of functional KAI2 receptors varies among plant species. It

Mud motors are widely used in directional drilling and their failure during operation leads to costly non-productive time. There is currently no existing literature investigating the correlation between stalls detected using downhole sensors and conc
