Plants produce both leaf and flower primordia cells at the shoot apical meristem (SAM). Primordium development in plants is critical to the proper positioning and development of plant organs and cells. The process of primordium development is intricately regulated by a set of genes that affect the positioning, growth and differentiation of the primordium. Genes including STM (shoot meristemless) and CUC (cup-shaped cotyledon) are involved in defining the borders … WebAug 5, 2024 · After thawing, shoot primordia were isolated from the winter buds under a stereo light microscope (SMZ-10, Nikon, Tokyo, Japan) using tweezers and a scalpel. The isolated shoot primordia were sterilized by immersion in 70% ethanol for 20 s and 0.5% sodium hypochlorite for 3 min, before being rinsed three times with autoclaved water.
