Physiological and proteomic responses to salt stress in chloroplasts of diploid and
tetraploid black locust (Robinia pseudoacacia L.).
In these cases, the [p57.sup.-] cells are androgenetic (usually diploid) and the [p57.sup.+] cells are biparental (usually also diploid, but some can be triploid or
tetraploid or a mixture of these).31,32,34 The p57 immunostain is interpreted as "divergent" when 2 populations of villi, each with different morphologies, exhibit 2 different staining patterns (eg, a typical "negative" result in one set and typical "positive" result in the other set).
Two kinds of warm-season grasses, Chloris gayana Callide' (CG) and Brachiaria ruziziensis,
tetraploid strains 'OKI-1' (BR) were studied.
The
tetraploid scallops used in this study were progeny from the only family reported in Maldonado-Amparo et al.
Of the three populations, two were
tetraploid and one was sympatric pure diploid, triploid,
tetraploid plus mosaic.
Sampling.--Six populations were used in this study, including two comprised solely of diploid individuals, two comprised solely of
tetraploid individuals, and two of mixed-ploidy (i.e., including diploid and
tetraploid individuals) (Table 1).
