TaMYB-D7 alleles mediate leaf pigmentation in response to nutrient status in wheat

/in /by

Nitrogen and phosphorus are essential macronutrients for wheat (Triticum aestivum L.) growth and development, and phosphorus deficiency is often associated with purple pigmentation in leaves due to anthocyanin accumulation. For farmers and growers, this pigmentation can be read as a sign of phosphorus deficiency. A recent study by Zhang et al. found that contrasting leaf […]

In planta directed evolution: Turning a single leaf into a laboratory of quasi-infinite variants

/in /by

Directed evolution aims to identify variants of a gene of interest (GOI) with improved or novel functions by accelerating mutation and selection under experimental conditions. However, in planta platforms have been hindered by slow plant cell division. Recently, Zhu et al. introduced the geminivirus replicon–assisted in planta directed evolution (GRAPE) platform, enabling rapid improvement or […]
