The Role of Cytokinin in Female Gametophyte Development in Arabidopsis [PDF]

open access: yes, 2013
Plants, unlike animals, have distinct haploid and diploid phases of their life cycle. The haploid female gametophyte develops within the diploid maternal sporophytic tissue.

New insights on the expression patterns of specific Arabinogalactan proteins in reproductive tissues of Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2022
Arabinogalactan proteins (AGPs) are hydroxyproline-rich glycoproteins containing a high proportion of carbohydrates, widely distributed in the plant kingdom and ubiquitously present in land plants. AGPs have long been suggested to play important roles in

Reproductive Strategies of the Female Gametophyte

open access: yes, 2023
Reproduction refers to the biological process of producing offspring. Sexual reproduction in angiosperms is a complex and precise process of regulation, which requires the mutual recognition of male and female gametes. The pollen tube, as a medium for transmission of male gametes, is attracted by chemoattractant derived from synergid cells in a target ...

Development of Female Gametophyte in Gladiolus italicus Miller (Iridaceae)

open access: yes, 2021
In this study gynoecium, megasporogenesis, megagametogenesis and female gametophyte of Gladiolus italicus Miller were examined cytologically and histologically by using light microscopy techniques. Ovules of G.

Identification of genes expressed in the angiosperm female gametophyte [PDF]

open access: yesJournal of Experimental Botany, 2010
Until recently, identification of gene regulatory networks controlling the development of the angiosperm female gametophyte has presented a significant challenge to the plant biology community. The angiosperm female gametophyte is fairly inaccessible because it is a highly reduced structure relative to the sporophyte and is embedded within multiple ...

Genetic Analysis of Female Gametophyte Development and Function [PDF]

open access: yesThe Plant Cell, 1998
The female gametophyte is an absolutely essential structure for angiosperm reproduction. It produces the egg cell and central cell (which give rise to the embryo and endosperm, respectively) and mediates several reproductive processes including pollen tube guidance, fertilization, the induction of seed development, and perhaps also maternal control of ...

Cell-Cell Communication among the Component Cells of Female Gametophyte and between Male and Female Gametophytes [PDF]

open access: yesSCIENTIA SINICA Vitae, 2015
Double fertilization in angiosperm is a complex and tightly regulated process. Successful fertilization depends on the development of gametophytes and the communication between female and male gametophytes. Studies revealed that there existed a wide range of intercellular communication among the component cells of the female gametophyte themselves ...
