Ralstonia solanacearum Alters Root Developmental Programmes in Auxin-Dependent and -Independent Manners.

Microbial pathogens and other parasites can modify the development of their hosts, either as a target or a side effect of their virulence activities. The plant-pathogenic bacterium Ralstonia solanacearum, causal agent of the devastating bacterial wilt disease, is a soilborne microbe that invades host plants through their roots and later proliferates in xylem vessels. In this work, we studied the early stages of R.

Low-Frequency Phonon Dispersion Relation Enabling Stable Cathode from Spent Lithium-Ion Batteries.

Direct recycling technology can effectively solve the environmental pollution and resource waste problems caused by spent lithium-ion batteries. However, the repaired LiNiCoMnO (NCM) black mass by direct recycling technology shows an unsatisfactory cycle life, which is attributed to the formation of spinel/rock salt phases and rotational stacking faults caused by the in-plane and out-of-plane migration of transition metal (TM) atoms during charge/discharge. Herein, local lattice stress is introduced into the regenerated cathode during repair.
