Lichens are remarkable, complex symbiotic organisms. They have evolved multiple times independently, but all lichen include at least one fungal partner (the mycobiont) which they usually resemble morphologically, and at least one cyanobacterial or algal photosynthetic partner (the photobiont). This partnership…

This study by Turner et al. looks at the patterns of leaf and sporangia arrangement in early leafy plant species, questioning the widely held idea that these structures follow the Fibonacci sequence. The researchers investigated fossilized remains from the Early Devonian period. To evaluate the spatial…

Developing broad-spectrum disease resistant crops without compromising the yield has been a persistent challenge in maintaining global food security. In a breakthrough study, Sha et al. developed a promising multi-pathogen resistant rice mutant that retains the crop’s yield, using forward genetic screen…

Like all of Earth’s lifeforms, plants are already experiencing hardships due to the changing climate, and these stresses will get more extreme. Much effort has gone into breeding crops for climate resilience, less on trees which are both more diverse and less genetically tractable. Here, Allsup et…

Recently, we highlighted a sexually deceptive daisy that mimics a female bee-fly to attract the male pollinators. In a recent preprint, Fattorini et al. take a closer look at the factors that specify the petal pigmentation pattern. The authors looked at three morphotypes with different spot patterns,…

When flooding occurs, soils become saturated and oxygen solubility and diffusion decreases. This situation creates a hypoxic environment in the roots that stresses the plant, causing significantly decreased growth. However, the quiescent center (QC) stem cells, located in the root apical meristem, are…

Recently, the United States designated Juneteenth as a new federal holiday, which celebrates freedom of the last large body of enslaved Black Americans following the American Civil War. However, the impact of chattel slavery persists: Black scientists face many obstacles to attaining an education and…

Biomolecular condensates are non-membrane-bound compartments containing proteins and RNAs with key functions in stress responses. In plants, they occur as several types with different properties and components, including stress granules and processing bodies. Protein domains such as prion-like domains…
