Expression pattern of the alpha-kafirin promoter coupled with a signal peptide from Sorghum bicolor L. Moench.

Regulatory sequences with endosperm specificity are essential for foreign gene expression in the desired tissue for both grain quality improvement and molecular pharming. In this study, promoters of seed storage α-kafirin genes coupled with signal sequence (ss) were isolated from Sorghum bicolor L. Moench genomic DNA by PCR.

Cryopreservation of in vitro-grown shoot-tips of tropical taro (Colocasia esculenta var. esculenta) by vitrification.

In vitro shoot-tips of three cultivars of tropical taro (Colocasia esculenta var. esculenta (L.) Schott) were successfully cryopreserved by vitrification.
