Dear Editor,Cadmium （Cd） is a toxic heavy metal and carcinogen, and its en- try into the food chain has serious effects on food security and public health （Uraguchi et al., 2011）. As rice is a staple food crop for half of the world＇s population, Cd in rice grain has become a major source of dietary Cd for this part of the world.

This paper provides a description of the articulated species of the Tribe Janieae (Corallinales, Rhodophyta) in the Pacific coast of Baja California and Gulf of California, Mexico. This taxonomic report is based on newly collected data in the study area and material currently housed at several herbaria. As a result of the present study, the record of the tribe Janieae is represented at the Pacific coast of Mexico for one genus: Jania J. V. Lamouroux with nine species. Morphological, reproductive and anatomical descriptions are provided in detail. In addition, keys for determination are included, as well as habitat, nomenclature, comparisons with other species and information on distribution. Instead of eleven species of Jania currently recorded for the study area, we recognize only nine. Jania verrucosa is restricted to the occidental coast from the Peninsula of Baja California. The remainder of the species commonly occurs in the Gulf of California and the Pacific coast of Baja California’s Peninsula. On the other hand, the gametangial thalli of J. adhaerens and tetrasporangial conceptacle in J. longiarthra are reported for the first time in Mexico.

It is a crucial problem in gene engineering whether an exogenous gene could be correctly expressed in cells of transgenic animal or plant, and how the expression products could be detected quantitatively in translational level. It is very difficult to analyze some gene expression products, such as isopentenyl transferase (ipt), in transgenic investigation because they are trace in organisms. A convenient method is described to determine trace content gene expression product which is hard to purify. The method includes predicting and synthesizing the antigenic peptide according to the cDNA sequence, coupling the synthetic antigenic peptide with carrier protein, raising specific antibodies against the synthetic antigen, and detecting the gene expression product by ELISA and Western blot.
