Results Fifty-one clones screened from 160 clones on the basis of Hae III digestion patterns were sequenced, and their sequences were deposited in the GenBank. Clone sequences (52.9%) belonged to Acidimicrobidae and 5 suborders of Actinobacteridae. The other clone sequences (47.1%), which formed one large distinct clade in phylogenetic tree among phylum Actinobacteria, may represent one new suborder or new class.

The twig production of different clones is different, from 5.5 twigs per month to 14.8 twigs per month. The rooting rate, root number and root length change regularly as the concentration of IBA goes up from 0.05 to 2.00 mg/L. At the concentration of 0.05 mg/L ppm IBA, rooting rate and root length are the highest. Cutting substrate also has eminent effect on rooting rate and survival rate, 50% peat plus 50% sub-top soil is the best substrate. The survival rate differs greatly among clones, from 56.7% to 90.0%. Rooting rate and survival rate change regularly as season changes. The rooting rate of May and June is middle, that of July and August is high and that of September and October drops rapidly. The survival rate is low in May, September and October and high in June, July and August.

All index proved that the P5776 cDNA library constructed in this research had high quanlity and could be used for further ESTs sequencing and analyzing. The amplified library of P5776 was screened on white-blue plates, and more than 5,000 white-clones were selected to culture in 96-well plates, then the high quanlity plasmids of white-clones were extracted by traditioal alkaline-lysis method using the Vitagene?96-easy plasmid extract kit. Through PCR primered by T3( the vector has T3 RNA polymerase promoter ), the target fragments of inserts were get. Then the inserts were taged by four different fluorescence-dye, and fractionated by capillary in ABI Prism? sequencer. More than 5,000 5′-ESTs had been sequenced and through rough selecting, 4,747 ESTs were remained for further research. Among the remained ESTs, more than 90% have longer lenth than 500bp, and there are less than 5% unable-read bases in every sequence.
