Antarctic krill is a species with fundamental importance for the Southern Ocean ecosystem. Their large biomass and synchronized movements, like diel vertical migration (DVM), significantly impact ecosystem structure biological carbon pump. Despite decades of research, mechanistic basis DVM remains unclear. Circadian clocks help organisms anticipate daily environmental changes, optimizing adaptation. In this study, we used recently developed activity monitor to record swimming individual, wild-caught under various light conditions across different seasons. Our data demonstrate how circadian clock, in combination light, drives distinct bimodal pattern activity, which could facilitate ecologically important behavioral patterns, such as DVM. Rapid damping flexible synchronization indicate that clock adapted life at high latitudes seasonal recordings suggest clock-based mechanism timing processes. findings advance our understanding high-latitude adaptation key species.

As sessile organisms, plants must directly face various stressors. Therefore, have evolved a powerful stress resistance system and can adjust their growth development strategies appropriately in different stressful environments to adapt complex ever-changing conditions. Nevertheless, prioritizing defensive responses hinder growth; this is crucial factor for plant survival but detrimental crop production. such, comprehending the impact of adverse on not only fundamental scientific inquiry also imperative agricultural industry food security. The traditional view that hindered during defense due resource allocation trade-offs challenged by evidence exhibit both robust capabilities through human intervention.

Abstract Plants are sessile by nature, and as such they have evolved to sense changes in seasonality their surrounding environment, adapt these changes. One prime example of this is the regulation flowering time angiosperms, which precisely timed coordinated action two proteins: FLOWERING LOCUS T (FT) TERMINAL FLOWER 1 (TFL1). Both regulators members PHOSPHATIDYLETHANOLAMINE BINDING PROTEIN (PEBP) family proteins. These regulatory proteins do not interact with DNA themselves, but instead transcriptional regulators, D (FD). FT TFL1 were initially identified key time, acting through binding FD; however, PEBP also involved shaping plant architecture development. In addition, PEBPs can TCP TEOSINTE BRANCHED (TB1), a well-known regulator architecture, domestication-related genes many crops.

Abstract Plants undergo a series of developmental phases throughout their life-cycle, each characterized by specific processes. Three critical features distinguish these phases: the arrangement primordia (phyllotaxis), timing differentiation (plastochron) and characteristics lateral organs axillary meristems. Identifying unique molecular phase, determining triggers that cause transitions understanding mechanisms underlying are keys to gleaning complete plant development. During vegetative shoot apical meristem (SAM) facilitates continuous leaf stem formation, with development as hallmark. The transition reproductive phase induces significant changes in processes, driven mainly protein FT (FLOWERING LOCUS T) Arabidopsis proteins encoded orthologs, which specified ‘florigen’. These synthesized leaves transported SAM, act primary flowering signal, although its impact varies among species. Within florigen integrates other signals, culminating changes.

Although thousands of genes have been identified or cloned in rice (Oryza sativa) the last two decades, majority them only separately characterized specific varieties single-gene modified backgrounds, thus limiting their practical application. We developed an optimized multiplex genome editing (MGE) toolbox that can efficiently assemble and stably express up to twelve sgRNA targets a single plant expression vector. In this study, we established MGE-based Rapid Directional Improvement (MRDI) strategy for directional improvement complex agronomic traits one small-scale transformation. This approach provides rapid procedure, encompassing assembly, transgene-free screening creation promising germplasm, by combining precision gene with phenotype-based field breeding. The MRDI was used generate full diversity main cultivar FXZ its growth duration architecture. After applying FXZ, ideal plants desired early heading date reduced height, more effective panicles were generated without compromising yield, blast resistance grain quality. Furthermore, results whole-genome sequencing (WGS), including analysis structural variations (SVs) nucleotide (SNVs) MGE plants, confirmed high specificity low frequency unwanted mutations associated strategy. breeding would be robust exploring crucial genes, as well generating novel elite germplasm future.
