Mature plants can detect and respond to herbivore-induced plant volatiles (HIPVs) by priming or directly activating defenses against future herbivores. Whether other plant life stages can respond to HIPVs in similar manners is poorly understood. For example, seeds are known to respond to a variety...
Awns are normally suppressed in most japonica rice cultivars including Kitaake. All T1 MiMe progeny (n = 139) were scored for the phenotype of complete infertility and presence of awns, including 33 plants that were additionally confirmed in b by flow cytometry. Right, panicle of an S-Apo ...
seeds are more common in the dry forests of the forest-steppe zone (southern regions), as well as in pessimal conditions characterized by a cold thermal regime and excessive moistening of plantings near the northern border of the range [51]. The productivity of such pine forests is usually ...
