Recently the PINO l gene of the salt-tolerant wild rice Porteresia coarctata (Roxb.) was found to encode a salt-tolerant MIPS enzyme, as compared with the MIPS encoded by the salt-sensitive cultivated rice (Oryza sativa L.) (Majee et al., 2004). Comparison of MIPS sequences in these species revealed distinct differences in a 37 amino acid stretch, which upon deletion from the salt-tolerant MIPS rendered it salt-sensitive. Introgression of the PINO I gene via transformation rendered tobacco salt-tolerant. The genome of cultivated rice contains one gene encoding MIPS, termed RINOl. In addition to constitutive and...

Effects of stress due to different NaCl concentrations on the DF intensity and Pn of rice were studied. The results show that there is good correlation between the DF intensity and Pn, and that DF intensity can quantify the change of plant photosynthetic physiological status more accurately and faster under different NaCl concentration conditions. Therefore, it is likely that the DF technique will provide a potentially useful approach for non-invasive and real-time monitoring of the effects of NaCl stress on plant growth and photosynthetic metabolism and a powerful means in the selection of salt-tolerance of plants.

In addition to lactic acid producing bacteria, a few mycelial molds belonging to Rhizopus are good lactic acid producers. The ability of Rhizopus to produce only L-(-I-)-lactic acid aerobically under nitrogen-limited environments has been studied [25-28]. Compared to bacterial fermentation, Rhizopus requires only inorganic salts. In addition, Rhizopus cultures are more tolerant to a low pH environment. Consequently, pH maintenance is not as stringent as bacterial culture during lactic acid fermentation. Furthermore, Rhizopus molds are amy-lolytic that can produce lactic acid from starchy materials directly. For example, R. oryzae NRRL 395 was used to ferment starch derived from barley, cassava, corn, oat, and rice to L-lactic acid [25]. 

In general, zinc deficiency can be overcome by applying zinc salts to the soil, though the effect of a zinc-containing fertilizer on the mineral nutrition of rice depends on the planfs tolerance towards zinc deficiency. Organic compounds such as zinc chelates are more effective than inorganic salts with equivalent amounts of zinc (Vitosh etal. 1994). Phosphate application has also been suggested as a means of...
