Although they lack eyes, plants can differentiate between colors with a full complement of photoreceptors. Phytochromes (phys) are such photoreceptors dedicated to the visible light spectrum ranging from red light (600-700 nm) to far-red light (700-750 nm). phys are some of the most studied genes and control plant architecture and flowering time. phyA is a […]

Meiosis takes a single, diploid cell and turns it into four haploid spores. The equal distribution of genetic material is critical for genome stability across generations, and relies heavily on proper pairing of chromosomes and their timely release. During the first meiotic division, crossovers (COs) are responsible both for the exchange of genetic material between […]
Plant growth and development are extremely adaptable to changes in the external environment, including nutrient status, light quality and intensity, and temperature. Thanks to their developmental plasticity, plants can also initiate new organs from differentiated tissue following wounding, to the benefit of horticulturists everywhere. Plants establish a balance between cell proliferation and cell growth that […]
The ability to acclimate to high temperatures that are normally lethal is common to virtually all organisms on the planet. A short exposure to milder heat stress informs organisms that they should ready themselves in case they experience even warmer conditions. Acquired thermo-tolerance in plants is important because plants must constantly balance growth and defense; […]
