    Gene transcription and transcriptional regulation are crucial biological processes in all cellular life. Through the next-generation sequencing (NGS) technology, transcriptome data from different tissues and developmental stages can be easily obtained, which provides us a powerful tool to reveal the transcriptional landscape of investigated tissue(s) at special developmental stage(s).Author: Xiangyuan Wan, Ziwen Li.   gametophyte In plants and algae that undergo alternation of generations, a gametophyte is the multicellular structure, or phase, that is haploid, containing a single set of chromosomes: The gametophyte produces male or female gametes (or both), by.

The morphology of Cryptothallus Class: Jungermanniopsida. The repeated origin of such a complex ontogenetic sequence makes Fritillaria-type female gametophyte development an ideal subject for an evolutionary developmental investigation.

Yet, basic knowledge of this ontogeny in angiosperms is limited, and the developmental basis for the origin of this female gametophyte type has never been by: 9. Third, within a pistil/ear of a heterozygous female gametophyte mutant, half of the female gametophytes are genotypically wild type and half are genotypically mutant ; thus, the developmental stage of wild-type female gametophytes can be used to determine the developmental stage of mutant female gametophytes (Christensen et al., ).Cited by: The development of reproductive structures in Cryptothallus is not controlled by photoperiod, but does require a temperature of at least 21 °C (70 °F) following a period of sufficiently low : Aneuraceae.

Because of the homothallic nature of many pteridophytes, two categories of mating are possible: intragametophytic selling (the origin of both gametes from a single gametophyte) and inter-gametophytic mating (the origin of each gamete from a different gametophyte).Various morphological and genetical criteria (placement of the gametangia on the thallus, their sequence of Cited by: This means that the gametophyte is larger in size and lives longer than the sporophyte generation.

So when you are looking at the green leafy part of a moss, this is the gametophyte generation. This book studies the developmental biology of fern gametophytes, from their beginning through growth and maturation to their reproductive strategies.

It is intended to interest and instruct advanced undergraduates and graduate students and to make an important contribution to teaching cell and developmental by: As the only land plants with a dominant gametophyte generation, liverworts, mosses, and hornworts exhibit structural and reproductive attributes that are exclusive, unifying, and innovative.

Their persistent gametophyte is responsible for exploratory growth as well as for proliferation of a new generation through either sexual or asexual by: Gene regulatory networks controlling early reproductive development The plant life cycle alternates between a haploid gametophyte generation and a diploid sporophyte g eneration.

Angiosperms have two gametophytes: the female (also referred to as the embryo sac) and the male gametophyte (also referred to as the pollen grain).
