Celery collenchyma

We performed RNA-Seq analysis of different petiole tissues of celery (Apium graveolens L., var. secalinum Yablochny). Plants were grown in pots with a soil layer of 50 cm in the greenhouse (22-24 grad. of Celsius) under lamp light (a day period 16 h) with daily watering. Samples were collected at 32-34 days (S1 samples) and 90-94 days (S2) after planting. We collected collenchyma (Col), parenchyma (Par), vascular bundle (Vas), and petiole segments without collenchyma strands (CF, collenchyma-free samples).

本研究对芹菜（*Apium graveolens* L. var. *secalinum* Yablochny）的不同叶柄组织开展了RNA测序（RNA-Seq）分析。试验植株种植于温室中土层厚度为50 cm的花盆内，培养条件为：温度22~24摄氏度，人工灯光照明，光照周期16小时，每日浇水。分别于定植后32~34天（记为S1样本）与90~94天（记为S2样本）采集样品，采集的组织样本包括厚角组织（Col）、薄壁组织（Par）、维管束（Vas）以及不含厚角组织束的叶柄切段（CF，即无厚角组织样本）。
