That study also found that expression of reporter gene GT5211 greatly increases as cells begin to adopt the characteristic shape of this tissue, in concert with Athb8-GUS which appears as this tissue begins to connect with existing veins.
A 2004 study by Enrico Scarpella and Philip Francis showed a strong correlation between the expression of ET13350-GUS and the development of this in Arabidopsis. That study also found that expression of reporter gene GT5211 greatly increases as cells begin to adopt the characteristic shape of this tissue, in concert with Athb8-GUS which appears as this tissue begins to connect with existing veins. Lying just below the tissue that is to develop into the stem epidermis, the straw-like cells of this tissue develops into a type of secondary meristem and gives rise to the two main types of plant vacular tissue. For ten points, identify this tissue of the meristem that develops into primary xylem and phloem and produces the vascular cambium.
