A series of independent human-induced non-transgenic mutations found in an expansin gene of tomato; tomato plants having these mutations in their LeExp1 genes; and a method of creating and identifying similar andor additional mutations in the LeExp1 gene by screening pooled andor individual tomato plants. The video camera includes a cassette detecting portion 2 detecting ejection of the cassette tape from the opening, and a cassette insertion preventing mechanism 5 preventing re-insertion of the cassette tape when the cassette detecting portion 2 detects ejection of the cassette tape. The crust is mechanically reinforced by at least one preformed refractory body. The ratio of width in the axis direction of the round wire 17 or the oval wire to the width of the bottom of the trapezoidal wire 16 is 0. In addition, fabrics having first and second surfaces that exhibit different performance characteristics, such as one surface exhibiting oil and water repellency and optionally, soil release characteristics, and the opposite surface exhibits moisture transport characteristics. An actuator is included that is configured to change the operational state of the dock component in response to an activation signal.
