A fascinating biological phenomenon is where a root tip can be surgically removed at a distance from the stem cell niche, yet the root still robustly grows back to its initially tapered shape. Mathew et al. investigated the cellular mechanism for how root regeneration can re-develop this tapered shape…

Leaf senescence, which overlaps with the reproductive growth phase in annual plants, constitutes the last stage in the development of a leaf, and several endogenous and exogenous factors control this, ultimately influencing the plant’s fitness, crop yield quantity and quality. The WRKY family of transcription…

Plants use several photoreceptors to perceive light including the cryptochromes (CRYs), which are implicated in blue-light reception and coordinate developmental processes including photomorphogenesis. Here, Liu et al. shed light on how light and temperature cues simultaneously affect plants. They identified…

Flowers are not only a source of beauty and awe but also an important agronomical trait, since many crop yields depend on the proper timing of flowering. With increasing fluctuations in temperature, plants must finely tune the flowering process. In Arabidopsis thaliana, flower primordia formation at…

Producing completely homozygous lines in a single generation is crucial for accelerating hybrid breeding in crops like rapeseed (Brassica napus), yet conventional in vitro methods are time-consuming and genotype-sensitive. In this study, Bakhsh et al. developed an efficient in vivo haploid induction…

Plants have their own version of an immune system—and it’s smarter than you might think. Through a process called Systemic Acquired Resistance (SAR), plants can “remember” an attack and prepare for the next one, arming themselves with long-lasting, broad-spectrum immunity. When one leaf is infected,…

Running on empty: How does the absence of mtDNA shape mitochondrial movement and connectivity? Mitochondria move within cells to support bioenergetic function and enable sharing of content, including mitochondrial DNA (mtDNA). Since not all plant mitochondria carry a full set of, or any mtDNA, sharing…

Behind the Plant Physiology manuscripts are researchers, professors, professionals and students dedicated to advancing the field of plant science. You’ve seen our First Authors on Bluesky, Facebook, and Twitter — now, read more about why they chose to pursue plant sciences and click on the links…
