Molecular hydrogen (H2) has been shown to have several cellular benefits, most notably serving as an antioxidant. Its effects in humans and plants have been primarily assayed using hydrogen-rich water (HRW, produced by bubbling H2 into water), but slower, more persistent release of H2 has been demonstrated…

In angiosperms, pollen germination leads to a period of extensive polarized growth of the pollen tube, which carries the sperm nuclei to the ovule. Studies of tip growth in both pollen tubes and root hairs have contributed to a descriptive model that involves polarized vesicle movement along the cytoskeleton…

Stomata are pores on leaves which enable gas exchange. In grasses, stomata are surrounded by dumbbell-shaped guard cells that are flanked by subsidiary cells. However, the role of the subsidiary cells in stomatal closure is not fully understood. Here, Liu et al. investigated this using two maize (Zea…

Insect pests pose a significant threat to global crop production, with lepidopteran species like corn earworm and armyworms causing substantial losses. The widespread use of insecticidal proteins from Bacillus thuringiensis (Bt) in crops has been a key strategy to combat these pests. However, the emergence…

The quality of student-advisor relationships is one of the top predictors of research progress and sense of belonging in science, yet in most cases the mentoring relationship is simply left to chance. In this preprint, Debray et al. surveyed a cohort of PhD students to understand what mentoring practices…
