Negative Regulation of Abscisic Acid Signaling by the Fagus sylvatica FsPP2C1 Plays A Role in Seed Dormancy Regulation and Promotion of Seed Germination

AbstractIt is well documented that the mother plant has much more influence than the father on seed dormancy/germination, especially of the F1 offspring, primarily by providing all material (maternally derived tissue) to the diaspore coat(s); by maternal environmental effects and provisioning of nutrient resources, mRNA transcripts, protein, the hormone abscisic acid and nitrate to the seed during its development; and by determining progeny environment via dispersal and phenology. There is some evidence that the paternal influence on seed dormancy/germination of the offspring (seeds) can be mediated through multiple paternity (including mate number and diversity), non-nuclear (cytoplasmic) and nuclear (genotypic) inheritance and paternal environmental effects. Our primary aim was to determine via a literature review the influence (or not) of the paternal parent on seed germination. Altogether, 37 of 59 studies (62.7%) indicated a positive influence of the father on seed germination, although not all of them were statistically significant. In general, however, results of studies reported in the literature do not offer strong support for the paternal parent having a major role in seed germination (or seed size) of his F1 offspring.

Critical Phase

The most critical phase in plant life is the germination period, which is influenced by both intrinsic and environmental factors. Assessment of cold stratification on several endogenous hormone, IAA, abscisic acid (ABA), gibberellin GA1/3 (GA1/3), zeatin-riboside (ZRs) and isopen-tenyl adenine (iPAs), and germination of Cornus walteri Wanger. seeds was done. Relationship between endogenous hormone and seed germination and mechanism of seed dormancy of C. walteri were also analysed. The results showed that the significant fluctuatation of both IAA and iPAs content was fond during cold stratification period, while the variation of ZRs was little, that of both ABA and GAs content increased with old stratification days. Effects of cold stratification on both GR and GP were significant (p < 0.05), which play an important role in releaving of seed germination and improving seed germination. The GR and GP were significantly negatively correlated with the contents of ABA and GA1/3, and positively correlated with the following iPAs, ZRs/ABA, iPAs/ABA.
