ASYMMETRIC LEAVES2-LIKE38/LBD41 gene of Arabidopsis is a member of the ASYMMETRIC LEAVES2 (AS2)/LATERAL ORGAN BOUNDARIES (LOB) domain gene family. To explore ASL38 function, we transformed 35S:ASL38 constructs into cockscomb (Celosia plumosus) plants via Agrobacterium tumefaciens and obtained T1 35S:ASL38 plants. The extremely folded or crinkly leaves were seen in these T1 cockscomb plants. The anatomical analysis of these malformed leaf blades indicated that adaxial cells revealed abaxialized traits, which were never seen in those of wild-type plants. These results suggested that ectopic expression of ASL38 might lead to alternations of dorsoventrality in folded or crinkly leaves of 35S:ASL38 cockscomb. In general, all data showed that ASL38 might be involved in dorsoventral determination in lateral organ development of plants.

In vitro shoot proliferation from stem disc of Allium chinense, a vegetatively propagated plant, was investigated in this experiment. In the present study, shoots were formed directly on stem discs on a medium containing 1 mg/l N⁶-benzyladenine (BA) and 0.5 mg/lα-naphthaleneacetic acid (NAA). These shoots were further cultured on MS media supplemented with various levels of BA in combination with NAA, and new shoot clusters developed easily from the explants cultured despite considerable differences in the induction of shoot clusters with different levels of BA and NAA. The most productive combination of growth regulators proved to be 1.0 mg/l BA and 1.0 mg/l NAA, in which about 17 shoots were produced per cluster in 8 weeks culture. Most of the formed shoots were rooted 15 days after being cultured on MS media supplemented with 0.1–1.0 mg/l NAA. The survival rate of the plantlets under ex vitro conditions was 95% in pots filled with a peat: sand (2:1 v/v) mixture after two weeks. In vitro bulblet formation were strongly promoted by the high temperature of 30℃ compared to that at 25℃, 20℃ and 15℃, and 12% (w/v) sucrose appeared to be optimal for bulblet development. Results from this study demonstrated that A. chinense could be in vitro propagated by using stem discs and in vitro bulblet formation could be achieved.
