Regulatory components called upstream open reading frames (uORFs) are commonly found in eukaryotic mRNA molecules. These uORFs regulate the translation rate of downstream coding sequences. Xue et al. edited uORFs added or edited uORFs in several genes to investigate the effects of adding or extending…

Brassinosteroid hormones regulate root growth and development by controlling cell division and elongation. However, it has been unclear why and how root cells with different identities and developmental stages respond to brassinosteroids differently. Nolan et al. used cutting-edge single-cell RNA sequencing…

C4 photosynthesis is derived from C3 photosynthesis. When related genes are compared, those involved in C4 photosynthesis tend to be more highly expressed. To understand this phenomenon, Singh et al. undertook a very impressive approach to look at transcriptional regulation of essentially all the photosynthetic…

Climate change is having negative effects on yield of economically important crops such as rice. Therefore, there is a pressing need for climate-change adapted crops. Previous research has highlighted that a decrease in stomatal density can enhance drought tolerance. EPIDERMAL PATTERNING FACTOR-LIKE9…

The (apparently delicious) fruit called atemoya is produced from a hybrid of Annona squamosa (sugar apple) × Annona cherimola (cherimoya), native to the American tropics but now grown widely. The hybridization event led to plants with several ploidies; diploid, triploid and tetraploid, which serve as…

This is one of those “straight into the textbook” stories. Kellenberger et al. investigated the unusual petal pigmentation pattern of a South African daisy Gorteria diffusa, which has petals with odd lumpy irregular spots that mimic female flies and enhance pollination through sexual deception. The…

The pressing need to restore degraded areas has led to an unprecedented demand for native seeds. However, seeds are not always available in sufficient quantity and quality in nature, so some restoration practitioners might opt to source their seeds from wild plants grown on farms, just like any crop.…

Review: Proximity labeling in plants Genetic studies can suggest that two proteins function in the same pathway, but how can we figure out if they share the same space? In this review, Xu et al. provide an overview of proximity labeling, a method to identify proteins that co-localize in space. Proximity…
