Plant Reprod 2018 Dec 13. Epub 2018 Dec 13.

State Key Laboratory of Hybrid Rice, College of Life Sciences, Wuhan University, Wuhan, 430072, China.

Plant zygotes usually undergo asymmetrical cell division, giving rise to the formation of two daughter cells with distinct developmental cell fate. The small apical cell will develop into the major part of embryo proper, whereas the larger basal cell will divide to form a transient suspensor. Thus, the apical and basal cell lineages are an excellent model to study cell fate determination in relation to zygote polarity. Read More

Department of Applied Mathematics, Peter the Great St.Petersburg Polytechnic University, St. Petersburg, Russia.

The impact of deleterious variation on both plant fitness and crop productivity is not completely understood and is a hot topic of debates. The deleterious mutations in plants have been solely predicted using sequence conservation methods rather than function-based classifiers due to lack of well-annotated mutational datasets in these organisms. Here, we developed a machine learning classifier based on a dataset of deleterious and neutral mutations in by extracting 18 informative features that discriminate deleterious mutations from neutral, including 9 novel features not used in previous studies.

Host Regulators of Liver Fibrosis During Human Schistosomiasis.

Front Immunol 2018 28;9:2781. Epub 2018 Nov 28.

Cape Town Component, International Centre for Genetic Engineering and Biotechnology, Cape Town, South Africa.

Liver fibrosis is a wound-healing process purposely aimed at restoring organ integrity after severe injury caused by autoimmune reactions, mechanical stress or infections. The uncontrolled solicitation of this process is pathogenic and a pathognomonic feature of diseases like hepatosplenic schistosomiasis where exacerbated liver fibrosis is centrally positioned among the drivers of the disease morbidity and mortality. Intriguingly, however, liver fibrosis occurs and progresses dissimilarly in schistosomiasis-diseased individuals with the same egg burden and biosocial features including age, duration of residence in the endemic site and gender.

The consequences of altered flowering dates due to climate change can be severe, especially for plants that rely on coordinated flower and pollinator emergence for reproduction. The plant Asclepias syriaca (Common Milkweed) relies on pollinators for movement of its pollen and evidence suggests that it has recently been declining. Given these factors and this plant's importance as a host species for the declining Danaus plexippus (Monarch Butterfly), it is critical to determine if its flowering is being modified by climate change.

Acidic soils, where aluminum (Al) toxicity is a major agricultural constraint, are globally widespread and are prevalent in developing countries. In sorghum, the root citrate transporter SbMATE confers Al tolerance by protecting root apices from toxic Al, but can exhibit reduced expression when introgressed into different lines. We show that allele-specific transactivation occurs and is caused by factors located away from Using expression-QTL mapping and expression genome-wide association mapping, we establish that transcription is controlled in a bipartite fashion, primarily in but also in Multiallelic promoter transactivation and ChIP analyses demonstrated that intermolecular effects on expression arise from a WRKY and a zinc finger-DHHC transcription factor (TF) that bind to and -activate the promoter.

A Golgi-released subpopulation of the trans-Golgi network mediates protein secretion in Arabidopsis.

Plant Physiol 2018 Dec 13. Epub 2018 Dec 13.

RIKEN CITY: Saitama POSTAL_CODE: 351-0198 Japan [JP].

Spatiotemporal coordination of protein trafficking between organelles is essential for eukaryotic cells, and the post-Golgi interface, including the trans-Golgi network (TGN), is a pivotal hub for multiple trafficking pathways. The Golgi-released independent TGN (GI-TGN) is a compartment described only in plant cells, and its cellular and physiological roles remain elusive. In Arabidopsis thaliana, the SYP4 group Qa-SNARE (soluble N-ethyl-maleimide sensitive factor attachment protein receptor) membrane fusion proteins are shared components of TGN and GI-TGN and regulate secretory and vacuolar transport.

Kyung Hee University CITY: Yongin STATE: Gyeonggi-do POSTAL_CODE: 17104 Korea (South), Republic Of

Root hairs are important for absorption of nutrients and water from the rhizosphere. The ROOT HAIR DEFECTIVE-SIX LIKE (RSL) Class Ⅱ family of transcription factors is expressed preferentially in root hairs and has a conserved role in root hair development in land plants. We functionally characterized the seven members of the RSL Class II subfamily in the rice (Oryza sativa) genome. Read More

Possible role of phytoestrogens in breast cancer via GPER-1/GPR30 signaling.

Clin Sci (Lond) 2018 Dec 13;132(24):2583-2598. Epub 2018 Dec 13.

Estrogens generated within endocrine organs and the reproductive system act as ligands for at least three types of estrogen receptors. Estrogen receptors α (ERα) and β (ERβ) belong to the so-called classical family of estrogen receptors, whereas the G protein-coupled receptor GPR30, also known as GPER-1, has been described as a novel estrogen receptor sited in the cell membrane of target cells. Furthermore, these receptors are under stimulation of a family of exogenous estrogens, known as phytoestrogens, which are a diverse group of non-steroidal plant compounds derived from plant food consumed by humans and animals.

The Arctic hosts a set of unique ecosystems, characterised by extreme environmental conditions and undergoing a rapid change resulting from the average temperature rising. We present a study on an aquatic ecosystem of the Revelva catchment (Spitsbergen), based on samples collected from the lake, river and their tributaries, in the summer of 2016. The landscape variety of the study site and the seasonal change in the hydrological regime modify the availability of nutrients. Read More
