Review: Strategies to improve photosynthesis
Plant Science Research WeeklyPhotosynthesis is the process by which plants assimilate carbon by using light energy. However, with the solar energy conversion efficiency of many crop plants less than 1%, it is inefficient. Therefore, there is interest in manipulating photosynthesis for increased efficiency. Here, Croce et al. identifying…
Review: Optimizing nutrient transporters to enhance disease resistance in rice
Plant Science Research WeeklyPlants rely on an array of mineral nutrients for their growth, development, and reproductive processes. The molecular mechanisms governing the uptake, translocation, storage, and utilization of these essential minerals are orchestrated by specific nutrient transporters and their associated regulatory…
Review: Proteolysis in plant immunity
Plant Science Research WeeklyPlant immunity is beautifully sophisticated with a ever-growing cast of characters. This review by Liu et al. focuses on the contributions of proteolysis (protein degradation), which both activates and suppresses immune responses. The authors structure the review around four key functions of proteolysis:…
Translocation of a chloride channel from the Golgi to the plasma membrane helps plants adapt to salt stress
Plant Science Research WeeklyPlants adapt to salt stress by maintaining ion balance using ion transporters. While much is known about cation transporters, the role of anion transporters is less clear. Rajappa et al. focus on the chloride channel gene AtCLCf in Arabidopsis thaliana, controlled by the transcription factor WRKY9 under…
Alone or together: BRI1 signaling controls root growth in a cell-autonomous manner
Plant Science Research WeeklyRoot growth is controlled by a dense network of hormone signals working in shared and distinct root zones and cell types. Brassinosteroids (BR) control root growth through activated signaling in vascular and epidermal tissues, but it is unclear how BR signals in each tissue contribute and whether there…
