Karyotypes of thirteen species of Iris L. from China

Cytological studies were carried out for 13 taxa in the genus Iris from China, of which three species, namely I. subdichotoma, I. delavayi and I. cuniculiformis were endemic to China. The chromosome numbers in somatic cells for each taxon were as follows: I. subdichotoma, 2n=42; I. japonica, 2n=34; I. wattii, 2n=30; I. laevigata, 2n=32; I. ruthenica var. nana, 2n=42; I. collettii, 2n=28; I. dolichosiphon and I. cuniculiformis, 2n=22; I. bulleyana, I. delavayi, I. chrysographes, I. forrestii, and I. lactea var. chinensis, 2n=40. The chromosome number and karyotype of I. cuniculiformis were reported here for the first time and its karyotype formula was 2n=22=4m+6sm+12st(2SAT). The karyotype of I. dolichosiphon was also firstly reported, whose karyotype formula was 2n=22=4m+12sm+6st. The chromosome number and karyotype of I. subdichotoma was newly observed, whose karyotype formula was 2n=42=20m+22sm. Three populations of I. ruthenica var. nana from different localities were investigated and all the three populations had the same chromosome numbers different than previously reported. The karyotype formulae for I. ruthenica var. nana were shown as follows: Zhongdian population, 2n=42=30m+12sm (2SAT); Lijiang population, 2n=42=28m+14sm(2SAT); Nixi population, 2n=42=36m+6sm (4SAT). In addition, the 2n chromosome numbers of three subgenera Limniris, Iris and Nepalensis in the genus Iris from present results and previous reports were summarized. The results showed that the chromosome number varied considerably in subgen. Nepalensis, in which I. subdichotoma was possibly a key species between the genus Pardanthopsis and subgen. Nepalensis. Chromosome number of I. ruthenica was reported as 2n=84 which was twice as much as its variety I. ruthenica var. nana (2n=42) we observed. By comparing with related groups, I. ruthenica is likely to derive from diploid group. Finally, variation of chromosome number and evolutional tendency of karyotype in the genus Iris were also discussed.

鱼腥藻PCC7120藻蓝蛋白α亚基体内重组研究

为了研究藻蓝蛋白α亚基的生物合成途径,通过构建相容的3种重组质粒pETDuet-cpcA、pCOLADuet-cpcE-cpcF和pACYCDuet-ho1-pcyA,将裂合酶基因cpcE和cpcF、血红素氧化酶基因ho1、藻蓝胆素合成酶基因pcyA和脱辅基藻蓝蛋白α亚基基因cpcA共同转入大肠杆菌BL21(DE3)。通过色素蛋白锌电泳和光谱检测表明产生了生物活性的CpcA-PCB。成功实现了大肠杆菌内藻蓝蛋白α亚基84位半胱氨酸残基与PCB的连接。而在裂合酶基因cpcE和cpcF不转入大肠杆菌的情况下,大肠杆菌内只有0.2%的CpcA-PCB产生。以上研究为进一步在大肠杆菌内合成天然的藻蓝蛋白奠定了基础。

Pollen morphology of the tribe Ruellieae (Acanthaceae) from

Pollen morphology of seven species in two genera in the Ruelliinae, three species in one genus in the Barlerinae and 34 species in 16 genera in the Strobilanthinae (Ruellieae, Acanthaceae), were observed under SEM. Pollen grains in Ruellieae, particularly in Strobilanthinae (including Strobilanthes s.l.) exhibit great diversity and are most eurypalynous in the family. In light of the aperture types and exine ornamentation patterns, pollen grains of the genera examined fall into three major types: 1. 3-porate pollen, which includes, (1) pollen with reticulate exine ornamentation (Pararuellia); (2) pollen with gemmate exine ornamentation (Championella); (3) pollen with echinate exine ornamentation (Paragutzlaffia, Diflugossa and Pteroptychia). 2. 3-colporate pollen or 3-colporate pollen with pseudocolpi, which includes, (1) 3-colporate pollen with reticulate exine ornamentation (Eranthemum and Barleria); (2) 3-colporate pollen with pseudocolpi and ribbed or banded, and septate exine ornamentation, the lumina rounded, finely reticulate inside and arranged in longitudinal rows (Perilepta, Pteracanthus, Goldfussia, Sympagis and some species of Strobilanthes); (3) 3-colporate pollen with ribbed or banded yet not septate exine ornamentation, the lumina neither distinctly rounded and finely reticulate inside, nor conspicuously arranged in longitudinal rows (Aechmanthera, Baphicacanthus, Semnostachya and some species of Pteracanthus); and (4) 3-colporate pollen with ribbed and finely reticulate exine ornamentation but with broader bands, each band with two ridges (Strobilanthes cycla). 3. (4-)5-colporate pollen with pseudocolpi and reticulate or ornate exine ornamentation (Adenacanthus). No distinct apertures were observed in three genera, Parachampionella, Gutzlaffia and Tarphochlamys. Pollen morphological characters in the Acanthaceae can be used not only to distinguish taxa of higher ranks (subfamily, tribe and subtribe) and elucidate their relationships, but sometimes can also be used to distinguish genera and species.
