(1) the primordium of the pituitary(2) The development is initiated as a hyphal knot of 0.2 mm or less in diameter, which rapidly develops into a tiny primordium containing the rudimentary tissues of the future pileus and stipe.(3) In flowers, both genes are expressed throughout inflorescence and floral meristems and in developing organ primordia .(4) Although mitoses were still detected in leaf primordia of that stage, cell differentiation had already started.(5) These organ primordia , which develop after a period of time corresponding to winter in temperate regions, are called preformed organs.(6) Microscopical examination for the fungal infection was performed on the bristles, adjacent hypocotyl surface and the internal tissue of root primordia .
