Isoflavones are the main active component of kudzu(Pueraria lobata).The first committed step in the production of isoflavones is performed by a cytochrome P450 enzyme,IFS.While IFS genes have been isolated from kudzu,no biological functions have been identified to date.We cloned an IFS gene via RT-PCR,named PlIFS,using kudzu collected from Langxi(Anhui,China)as plant material.The PlIFS contained an open reading frame(ORF)encoding 521 amino acid residues.The amplified PlIFS gene was cloned into pESC-TRP vector,with yeast GAL1 divergent promoters as the control.The constructed recombinant plasmid,named pESC-TRP-PlIFS,was transformed into Saccharomyces cerevisiae strain WAT11 according to the LiAc/ssDNA/PEG method.The PlIFS expressed in yeast was able to catalyze daidzein formation from liquiritigenin,indicating that it had IFS activity.Gene expression pattern analysis revealed that PlIFS was expressed in roots at the highest level,which was consistent with isoflavones accumulation in kudzu plantlets.

Xylem pressure probes are the only technique used currently to measure plant xylem pressure directly. This technique includes devices for accurate positioning,pressure probe systems and signal acquisition. Negative pressure of the xylem vessels is transmitted to the pressure sensor by conduction medium when the capillary probe punctures the xylem vessels, with the pressure then detected and transmitted to the data acquisition system. In this paper, the use and precautions of xylem pressure probes are described in detail,including the preparation of glass capillary probes,degassed water,pressure calibration,installation,and measurement of pressure probes.

Chromosome numbers of 24 populations from 13 species and 5 varieties,as well as karyotype data from 5 species and 1 variety of Chinese Bupleurum L.were reported.All were diploids,except two populations of B.tianschanicum,one of B.commelynoideum and one of B.marginatum were polyploids.(1) B.longicaule var.giraldii and B.petiolulatum var.tenerum may be two independent species;it is more appropriate for B.boissieuanum to be treated as a variety of B.longiradiatum,whereas treating B.commelynoideum var.flaviflorum as a variety of B.commelynoideum may not be appropriate;(2)B.commelynoideum and B.chinense are complex groups,which require further study;(3) The ancestral basic chromosome number of Bupleurum L.is x = 7,but this needs further evidence.
