Disruption of the endoplasmic reticulum-localized fatty acyl-ACP thioesterase IPF1 caused partial male sterility in rice.

The fatty acyl ACP thioesterases, catalyzing the final step of fatty acid synthesis in the plastid, regulate various critical processes in plants, including seed oil accumulation, seed development, plant growth, and drought tolerance. However, their roles in male fertility have seldom been demonstrated. In this study, the function of a newly FAT, Impaired Pollen Fertility 1 (IPF1) in male fertility was investigated.

Fabricating the Superhydrophobic Nickel and Improving Its Antifriction Performance by the Laser Surface Texturing.

The superhydrophobic surface can change the friction property of the material, reduce the adhesion of the friction interface, and produce a certain slip, thereby reducing the friction coefficient. The laser has high energy, high density, and is especially suitable for the surface treatment of materials. The laser surface texturing is a good way to construct superhydrophobic surfaces.
