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.
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
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).
pitardii-dyed section was observed in tetraploid
(4n) and hexaploid (6n) camellia plants, respectively.
Table 2: Mean values of Cd contents, RGR, Dry weight, BCF and STI with Cd alone as well as Cd in combination with salicylic acid of tetraploid
(Durum-97) and hexaploid (Shafaq-06) calli with standard errors.
potato cultivars because they are easily masked by the
The study was performed with the following treatments on 27 tetraploid
During the study, the research team genetically engineered mice to have bowel cancer, subsequently leading to the creation of more tetraploid
cells in their intestinal linings.

and haploid plants
