Cryo-electron microscopy reveals previously undescribed structural features of choanoflagellate flagella and provides new insights into flagellar evolution.

Based on two independent methods, mitochondria operate at temperatures up to 15°C hotter than ambient, adjusting their heat production so as to maintain temperature in face of physiological stresses.

Doc2B functions in two distinct vesicle priming steps; membrane localization occludes upstream Ca2+-dependent priming, whereas Ca2+-binding and interaction with synaptotagmin-1, SNAREs, and Munc13-2 are involved in downstream priming, which makes vesicles readily releasable.

CBFs, the central regulators of low-temperature signaling, have a function to directly activate the expression of COOLAIR, an antisense RNA of FLC, during vernalization process, but COOLAIR is not required for the vernalization response.

Storage of solar energy in the thylakoid electrical field by photosynthesis in vivo can substantially destabilize charge-separated states in photosystem II, leading to singlet oxygen production and photodamage, contributing to loss of productivity, especially under fluctuating light experienced in the field.

CaMKII is capable of spreading activity between holoenzymes without exchanging subunits.

Molecular structure of mitochondrial complex I from Drosophila melanogaster reveals a structural element not seen in other organisms to date that may regulate the transition between an off-pathway resting state and the active state of the complex.

Mitochondrial functional and structural defects caused by PARL deficiency lead to arrested spermatogenesis and germ cell ferroptosis.

The SNAP-25 linker acts as a functional component of SNARE complexes, initially facilitating SNARE interactions and later promoting fusion triggering and pore evolution by local membrane contacts.

Stramenopiles are unusual, because the pay-off phase of glycolysis occurs in mitochondria rather than the cytosol and the identified mitochondrial carrier links the two parts by transporting glycolytic intermediates.
