“…Following two longitudinal divisions of an apical cell, the same genes were found to be activated in embryo proper, however, after transverse divisions, when an embryo reaches 8-cell stage, upper and bottom tiers display different gene expression which is controlled by auxin threshold [60,113,114]. Thus, auxin transporters, whose expression is induced by high auxin level [115,116], regulate polar auxin transport and thereby generate auxin maxima in different tissues. A family of auxin transporters is a good example of genes differently expressed in various cells.…”

In plants, the first asymmetrical division of a zygote leads to the formation of two cells with different developmental fates. The establishment of various patterns relies on spatial and temporal gene expression, however the precise mechanism responsible for embryonic patterning still needs elucidation. Auxin seems to be the main player which regulates embryo development and controls expression of various genes in a dose-dependent manner. Thus, local auxin maxima and minima which are provided by polar auxin transport underlie cell fate specification. Diverse auxin concentrations in various regions of an embryo would easily explain distinct cell identities, however the question about the mechanism of cellular patterning in cells exposed to similar auxin concentrations still remains open. Thus, specification of cell fate might result not only from the cell position within an embryo but also from events occurring before and during mitosis. This review presents the impact of auxin on the orientation of the cell division plane and discusses the mechanism of auxin-dependent cytoskeleton alignment. Furthermore, close attention is paid to auxin-induced calcium fluxes, which regulate the activity of MAPKs during postembryonic development and which possibly might also underlie cellular patterning during embryogenesis.

BackgroundThe genus Liriodendron is ancient and contains only two species, L. chinense and L. tulipifera. These two Liriodendron sister species, with a typical intercontinental discontinuous distribution in east Asia (L. chinense) and eastern North America (L. tulipifera), have great scientific value for paleobotany systematics. L. chinense is now recognized as an endangered species partially due to its low natural settling rate. In order to improve our understanding of how this species develops and grows and contribute to protecting this valuable relict species from extinction, it is necessary to explore the mechanisms underlying organ morphogenesis and embryonic development, in which auxin plays an important role. The auxin efflux carrier PIN-FORMED (PIN) proteins are required for the polar transport of auxin between cells through their asymmetric distribution on the plasma membrane, thus mediating the differential distribution of auxin in plants and, finally, affecting plant growth and developmental processes.ResultsIn this study, 11 PIN genes were identified in the L. chinense genome. The structural characteristics and evolutionary status of LcPIN genes were thoroughly investigated and interpreted combining physicochemical property analysis, evolutionary analysis, gene structure analysis, chromosomal localization, etc. In addition, motif sequences were used to predict possible functional sites. Further qRT-PCR experiments and transcriptome data analysis indicated that LcPIN genes may potentially play an important role during organ development and somatic embryogenesis in Liriodendron. For example, specific expression of LcPIN3 and LcPIN6a at different developmental stages of stamens and petals suggests their involvement in the development of these organs.ConclusionThis study provides a foundation for further genetic and functional analyses of PIN-mediated auxin patterning during organ morphogenesis and embryogenesis in L. chinense.

Background: The pentatricopeptide repeat (PPR) gene family, which contains multiple 35-amino acid repeats, constitutes one of the largest gene families in plants. PPR proteins function in organelles to target specific transcripts and are involved in plant development and growth. However, the function of PPR proteins in cotton is still unknown. Results: In this study, we characterized a PPR gene YELLOW-GREEN LEAF (GhYGL1d) that is required for cotton plastid development. The GhYGL1d gene has a DYW domain in C-terminal and is highly express in leaves, localized to the chloroplast fractions. GhYGL1d share high amino acid-sequence homology with AtECB2. In atecb2 mutant, overexpression of GhYGL1d rescued the seedling lethal phenotype and restored the editing of accD and ndhF transcripts. Silencing of GhYGL1d led to the reduction of chlorophyll and phenotypically yellow-green leaves in cotton. Compared with wild type, GhYGL1d-silenced cotton showed significant deformations of thylakoid structures. Furthermore, the transcription levels of plastid-encoded polymerase (PEP) and nuclear-encoded polymerase (NEP) dependent genes were decreased in GhYGL1d-silenced cotton. Conclusions: Our data indicate that GhYGL1d not only contributes to the editing of accD and ndhF genes, but also affects the expression of NEP- and PEP-dependent genes to regulate the development of thylakoids, and therefore regulates leaf variegation in cotton.
