- Improving crop salt tolerance

Table 1. Species and genes used in the transformation of plants where authors claimed enhancement of salt tolerance

^a Asterisk indicates a specific prefix, e.g. At.

Table 2. Possible combinations for experiments reporting the evaluation of transgenic plants Column 1 lists experimental sites and column 2 the parameters that might be evaluated—yielding six possible combinations. In each combination, either quantitative or qualitative date might be reported on transformant and/or wild type, ideally under saline and non-saline conditions, but often only the transformant under saline conditions. Ideally, an experiment evaluating the effects of a transformation would report quantitative data on yield of field grown plants of both wild-type and transformant lines in the presence or absence of salinity.

Table 3. Criteria used to define categories of experiments where an enhancement of salt tolerance was claimed as a consequence of a transformation for plants and the numbers of experiments reported (between 1993 and early 2003) in each of those categories

Table 4. The effects of transformation (A) and hybridization (B) on the growth (g dry weight or fresh weight) or yield of plants in the presence and absence of salt

^a Weighted mean of three transformed lines.

^b Shoot dry weight.

^c Total PLANT dry weight.

^d Dry weight per plant: choline-supplemented wild-type (WT) and betaine-producing transgenic lines.

^e Fresh weight per plant: choline-supplemented wild-type (WT) and betaine-producing transgenic lines.

^f Grains per plant.

^g Average fruit yield, g fresh weight per plant.
