117 <td>Construction of an early carpel (pre-anthesis
118 through 5 days post-anthesis) cDNA library has been
119 completed. Approximately one millions unamplified
120 clones were generated and 300,000 were used in mass
121 excision. Forty 384-well plates (15,360 clones) were
122 picked. On hundred random clones were miniprepped and
123 PCR'd with an average insert size of 1.5 Kb (range
124 0.8-2.5 Kb). XhoI and EcoRI digests of the same 100
125 clones were performed. Only two clones were
126 identified with internal XhoI and EcoRI sites, which
127 may be indicative of chimeric ligation, though double
128 digestion suggested they were not chimeras (the
129 internal sites are both at least several hundred bp
130 internal, but not adjacent). 48 of the clones were
131 sequenced.Flowers were collected from about 25 TA496
132 plants every two days for one month. Flowers were
133 approximately 5 days pre-anthesis (based on tagging)
134 through 5 days post-anthesis (based on tagging and
135 appearance). At 5 dpa, the carpels were about 0.5 cm
136 in diameter. Flowers were collected at five different
137 stages: 1)5 days pre-anthesis, 2) anthesis (based on
138 partial sepal separation and anther tube swelling, 3)
139 5 dpa, 4) intermediate between 1 and 2, and 5)
140 intermediate between 2 and 3. About 0.5 grams of
141 tissue was collected from hundreds of flowers in the
142 early stages, while about 10 grams of tissue was
143 collected from about 10 stage-5 carpels. 0.5 to 1
144 gram per stage was combined and used for RNA
145 isolation. The carpels included ovules and embryos.
146 The anthers from the first three stages and some of
147 the fourth stage were collected for an anther
