Apomictic plants reproduce asexually through seeds by avoiding both meiosis and
fertilization. Although apomixis is genetically regulated, its core genetic component (s) has …

A novel transformation system was established for maize using Agrobacterium infection of in
vitro cultured ovules. The maize ovules were isolated 24 h after pollination and infected with …

Plant ovules provide zygotes with a physicochemical environment that supports embryo
differentiation, growth, and maturation. The exact nature of this embryogenesis-enabling …

Ovules of sunflower tubular florets were observed histologically by serial sectioning and
clearing to study the correlation between flower morphology and developmental stage. On …

Angiosperm embryology has entered a new phase, one that deals with isolated, living
embryo sacs or gametic cells. This phase of embryology has already produced a wealth of …

This chapter describes efforts to culture maize endosperm to enable direct developmental
and metabolic studies of the cereal endosperm organ without the effects of the maternal …

Isolated sperm cells and egg cells provide useful materials for the study of fertilization in
higher plants, under controlled conditions, in the absence of somatic tissue. Viable egg cells …

Several lines of evidences suggest that transitions during sexual plant reproduction are
epigenetically controlled through dynamic changes in chromatin structure. In asexual …

Установлена возможность получения жизнеспособных зародышей полной спелости в
культуре изолированных зерновок кукурузы на искусственной питательной среде в …

The possibilities for application of embryo culture as a practical method and an alternative
for obtaining hybrids from different crosses of cultivated maize (Zea mays L.) with wild …
