The gametophyte represents the sexual phase in the alternation of generations in plants; the
other, nonsexual phase is the sporophyte. Here, we review the evolutionary origins of the …

Spores and pollens refer to the reproductive cells of seed plants and asexually reproducing
sporophytes, exhibiting a natural core–shell structure and exquisite surface morphology …

Panicle architecture is a key determinant of grain yield in cereals, but the mechanisms
governing panicle morphogenesis and organ development remain elusive. Here, we have …

Current gene delivery methods for maize are limited to specific genotypes and depend on
time‐consuming and labor‐intensive tissue culture techniques. Here, we report a new …

Plant leaf senescence, caused by multiple internal and environmental factors, has an
important impact on agricultural production. The lectin receptor‐like kinase (LecRLK) family …

Research in angiosperm sexual reproduction is among the most classical botanical studies
with a rich knowledge base. The introduction of molecular tools since the late 1970s …

Rice (Oryza sativa L.) occupies a very salient and indispensable status among cereal crops,
as its vast production is used to feed nearly half of the world's population. Male sterile plants …

Pollen germination is a prerequisite for double fertilization of flowering plants. A
comprehensive understanding of the structural and molecular basis of pollen germination …

Starch accumulation is key for the maturity of rice pollen grains; however, the regulatory
mechanism underlying this process remains unknown. Here, we have isolated a male-sterile …

In higher plants, mature male gametophytes have distinct apertures. After pollination, pollen
grains germinate, and a pollen tube grows from the aperture to deliver sperm cells to the …
