tailieu.vn

However, the odds of normal or balanced embryo for BCCR carriers is very low. The effects of different types of BCCR on embryonic development andmolecular karyotype are not clear.. In our study, clinical and laboratory data on preim- plantation genetic testing to assist reproduction for three different types of BCCR carriers were collec- tedto explorethe difference of impacts of three types of BCCRs on embryo development and embryonic molecular karyotype..

Transcriptome dynamics in early in vivo developing and in vitro produced porcine embryos

tailieu.vn

Keywords: Transcriptomics, Porcine, Embryo development, In vivo embryo development, in vitro fertilization. Up to the blastocyst stage, embryos can be produced and cultured in vitro. Despite ongoing efforts to improve the quality of in vitro produced blastocysts, these embryos are less competent than in vivo developed blastocysts [5].

Structural variations in papaya genomes

tailieu.vn

These candidate genes are very important in the sexual reproduction and agronomic traits of papaya, such as pistil development, female gamete development, pollen tube growth, embryo development, flower time, crop yields, and peduncle elongation. For example, TOR is involved in embryogen- esis and is expressed in the embryo, endosperm, and meristem under Rapamycin [27, 28].

In silico characterization of putative gene homologues involved in somatic embryogenesis suggests that some conifer species may lack LEC2, one of the key regulators of initiation of the process

tailieu.vn

LEC2 is one of the central players in the process of seed and embryo development in plants . Similar to LEC2, LEC1 mediates not only the up-regulation of the auxin synthesis [100] but also facilitates effects of auxin to promote embryonic cell identity [101]. Protein se- quences of the candidates genes from A.

Genome-wide analysis of the citrus B3 superfamily and their association with somatic embryogenesis

tailieu.vn

The well-studied B3 member AtABI3, which is the putative ortholog of the Type II gene CsLAV2 (Cs5g34660) in Arabidopsis, has been demonstrated to regulate abscisic acid- responsive genes in phase transition from late embryo development to germination [8, 55], implying that CsLAV2 may also be functional in late embryogenesis.. CE and (or) E4 stages, suggesting their possible involvement in repression of the SE pathway, for transition to vegeta- tive development..

In the present study embryo cleavage was assessed at about 19–20 h post fertilization at ~ 10 °C and early embryo development or streak rate was estimated at about 10 days post fertilization for the 60 families in Group B (Table 1. The majority of the zygotes of families with eyeing rates greater than 80%, which we consider families with high quality eggs, reached at least the 16-cell stage, 91.6%, with some reaching the 32-cell stage, 43.2%.

Identification and analysis of the FAD gene family in walnuts (Juglans regia L.) based on transcriptome data

tailieu.vn

It is also possible that the α- linolenic acid content due to a lack of substrate in the early stage was not obvious early in embryo development in walnut. As the embryo matured, expression of JrFAD3-1 was downregulated, and the α-linolenic acid content increased. A total number of 24 members of the JrFAD gene family were identified and classified into four major subfamilis.

DNA methylation patterns vary in boar sperm cells with different levels of DNA fragmentation

tailieu.vn

Background: Sperm DNA integrity is considered essential for successful transmission of the paternal genome, fertilization and normal embryo development. has become a key parameter in the swine artificial insemination industry to assess sperm DNA integrity. Additionally, the DNA methylation profiles of the samples were determined by reduced representation bisulphite sequencing (RRBS).. Results: In this study, different traits related to sperm DNA integrity were investigated ( n = 18 ejaculates).

A study of the heterochronic sense/ antisense RNA representation in florets of sexual and apomictic Paspalum notatum

tailieu.vn

Then, at least a part of the differentially expressed transcripts detected at anthesis might be related alternatively to the induc- tion of parthenogenesis or to embryo development, since, at anthesis, embryos are forming in apomictic plants only. Interestingly, a methylation-mediated silencing mechanism was reported to control partheno- genesis in other species of the Paspalum genus [77].

As a member of the OSR family, OSR1 is a zinc finger transcription fac- tor that is required for embryonic development [52].. OSR1 is enriched in the pregranular cell population of females, indicating that the supporting cell progenitors are female-primed before gonadal sex differentiation in the chicken embryo [14]. ANXA2 plays a role in the development of chicken ovaries and follicles [54].
