In the postnatal period, cerebellar granule cells express a set of the maturation gene battery in an activity-dependent manner and establish synaptic function in the cerebellar circuitry. Using primary cultures combined with specific inhibition of signaling cascades, the present investigation revealed that the expression of the maturation genes, including the NMDA glutamate receptor NR2C and GA...

The seed maturation genes are specifically and highly expressed during late embryogenesis. In this work, yeast two-hybrid, bimolecular fluorescence complementation, and coimmunoprecipitation assays revealed that HISTONE DEACETYLASE19 (HDA19) interacted with the HIGH-LEVEL EXPRESSION OF SUGAR-INDUCIBLE GENE2-LIKE1 (HSL1), and the zinc-finger CW [conserved Cys (C) and Trp (W) residues] domain of ...

Seed maturation is mainly governed by a few genes best studied in maize and Arabidopsis. The isolation of the LEC1 and FUS3 genes, besides the previously known VP1/AB/3 genes, and their identification as transcriptional regulators provides the first direct hints as to their molecular mode of action. With the identification of new effector genes, the investigation of the role of hormones with ne...

Human offspring are weaned earlier than the offspring of other great apes but take longer to reach nutritional independence. An analysis of human disorders of imprinted genes suggests genes of paternal origin, expressed in infants, have been selected to favor more intense suckling than genes of maternal origin. The same analysis suggests that genes of maternal origin may favor slower childhood ...

In the exalbuminous species Arabidopsis thaliana, seed maturation is accompanied by the deposition of oil and storage proteins and the reduction of the endosperm to one cell layer. Here, we consider reserve partitioning between embryo and endosperm compartments. The pattern of deposition, final amount, and composition of these reserves differ between the two compartments, with the embryo repres...

Biologically, fruits are defined as seed-bearing reproductive structures in angiosperms that develop from the ovary. The fertilization, development and maturation of fruits are crucial for plant reproduction and are precisely regulated by intrinsic genetic regulatory factors. In this study, we used Arabidopsis thaliana as a model organism and attempted to identify novel genes related to fruit-a...

Nucleosome loss and histone modifications are important mechanisms for transcriptional regulation. Concomitant changes in chromatin structures of two peanut (Arachis hypogaea L.) oleosin genes, AhOleo17.8 and AhOleo18.5, were examined in relation to transcriptional activity. Spatial and temporal expression analyses showed that both AhOleo17.8 and AhOleo18.5 promoters can adopt three conformatio...

The mud crab, Scylla paramamosain, has abundant nutrients in the ovary, where numerous lipids accumulate during ovarian maturation. However, mechanism behind accumulation of ovary crab maturation is largely unknown. This study conducted a comparative transcriptome analysis ovaries crabs at various stages A total 63.69 Gb clean data was obtained, with Q30 93.34%, and 81,893 unigenes were identif...

Anther development is crucial for controlling crop fertility. To elucidate the underlying mechanisms of reproductive highland barley (called Qingke in Chinese), two main cultivars, Zangqing 2000 and Ximala 22, were utilized. Transcriptome analysis showed that lipid, sugar phenylpropane metabolisms might be major pathways associated with male fertility by analyzing possible common DEGs before an...

Changes in anthocyanin and endogenous abscisic acid (ABA) contents the berry skins of Vitis labruscana × V. vinifera cultivars, ‘Aki Queen’, ‘Ruby Roman’ were investigated during fruit development period. Color Queen’ berries mainly occurred within 20 days post véraison, while that was prolonged for about 40 days. In both ABA level skin started to increase a few before véraison; however, accumu...
