Abstract Vegetation cover regulates the exchanges of energy, water and carbon between land atmosphere. Remotely-sensed fractional absorbed photosynthetically active radiation (fAPAR), a land-surface greenness measure, depends on allocation to foliage while also controlling photon flux for photosynthesis. Here we use an equation with just two globally fitted parameters describe annual maximum fAPAR as smaller water-limited value transpiring constant fraction precipitation, energy-limited...
Abstract Zygotic genome activation (ZGA) marks the beginning of embryonic program for a totipotent embryo, which gives rise to inner cell mass (ICM) where pluripotent epiblast arises, and extraembryonic trophectoderm. However, how ZGA is connected first lineage segregation in mammalian embryos remains elusive. Here, we investigated role nuclear receptor (NR) transcription factors (TFs), whose motifs are highly enriched accessible from 2-cell (2C) 8-cell (8C) stages mouse embryos. We found...
Recent increases in vegetation greenness over much of the world reflect increasing CO2 globally and warming cold areas. However, strength response to both those areas appears be declining for unclear reasons, contributing large uncertainties predicting how will respond future global changes. Here, we investigated changes satellite-observed peak season absorbed photosynthetically active radiation (Fmax ) on Tibetan Plateau between 1982 2016. Although climate trends are similar across Plateau,...
“Greenness” is a key indicator of the functional state vegetation. However, physiological processes behind seasonal patterns in greenness are diverse and incompletely understood, hindering predictability climate-driven shifts global foliage phenology. Optimality principles suggest plants invest canopy architecture to maximize light capture. Therefore, we hypothesize, irrespective specific mechanisms, (fAPAR: fractional absorption) tracks dynamics potential production (A0:...
Leaf phenology, represented at the ecosystem scale by seasonal dynamics of leaf area index (LAI), is a key control on exchanges CO2, energy, and water between land atmosphere. Robust simulation phenology thus important for both dynamic global vegetation models (DGVMs) land-surface representations in climate Earth System models. There no general agreement how should be modeled. However, recent theoretical advance posits universal relationship time course "steady-state" gross primary...
The AP2/ERF family is an important class of transcription factors involved in plant growth and various biological processes. One the factors, RAP2.6L, participates stresses responses. However, function RAP2.6L largely unknown apples (Malus domestica). In this study, apple gene homologous to Arabidopsis AtRAP2.6L, MdERF113, was analyzed by bioinformatic characterization, expression analysis subcellular localization assessment. MdERF113 highly expressed sarcocarp responsive hormonal signals...
Abstract After fertilization, zygotic genome activation (ZGA) marks the beginning of embryonic program for a totipotent embryo, which further gives rise to pluripotent lineages and extraembryonic trophectoderm after first lineage commitment. While much has been learned about pluripotency regulation, how ZGA is connected commitment in early embryos remains elusive. Here, we investigated role nuclear receptor 1 family transcription factors (TFs) mouse pre-implantation embryos, whose motifs are...
Seasonal changes in leaf display, indicated by variations area index (LAI), play a crucial role influencing the exchange of CO2 and energy between terrestrial ecosystems atmosphere. Accurate simulation phenology is essential for both land surface models (LSMs) dynamic global vegetation (DGVMs). But there no agreement on how should be modelled. A common approach invokes specific physiological triggers budburst senescence, but domain application such restricted to plant types and/or climatic...

Vegetation cover regulates the exchanges of energy, water and carbon between land atmosphere. Remotely-sensed fractional absorbed photosynthetically active radiation (fAPAR), a land-surface greenness metric, depends on allocation to foliage while also controlling photon flux for photosynthesis. Greenness is thus both driver an outcome gross primary production (GPP). An equation with just two (globally) fitted parameters describes annual maximum fAPAR (fAPAR max ) as smaller water-limited...
Abstract Recent increases in vegetation cover, observed over much of the world, reflect increasing CO2 globally and warming cold areas. However, strength response to both appears be declining. Here we examine changes cover on Tibetan Plateau past 35 years. Although climate trends are similar across Plateau, drier regions have become greener by 0.31±0.14% yr−1 while wetter browner 0.12±0.08% yr–1. This divergent is predicted a universal model primary production accounting for optimal carbon...

Leaf phenology, often measured by the seasonal dynamics of leaf area index (LAI), is a key control on exchanges CO2 and energy between land ecosystems atmosphere. It therefore also target process for dynamic vegetation models. However, there no agreement how phenology should be modelled. Much research has focused specific triggers budburst– and, to lesser extent, senescence– in biomes characterized distinct cold or dry seasons. Recent theoretical developments however...
