Biological rhythms are ubiquitous. They can be generated by circadian oscillators, which produce daily in physiology and behavior, as well developmental oscillators such the segmentation clock, periodically produces modular units. Here, we show that clock controls timing of late-stage floret development, or anthesis, domesticated sunflowers. In these plants, up to thousands individual florets tightly packed onto a capitulum disk. While early development occurs continuously across capitula generate iconic spiral phyllotaxy, during anthesis discrete ring-like pseudowhorls with hundreds undergoing simultaneous maturation. We demonstrate regulation floral organ growth effects light on this process time-of-day dependent. Delays phase delay morning visits pollinators, while disruption causes loss pseudowhorl formation large reductions pollinator visits. therefore sunflower acts concert environmental response pathways synchronize each day, generating spatial patterns developing This coordinated mass release rewards at predictable times day likely promotes plant reproductive success.

Plant hormones are a group of small signaling molecules produced by plants at very low concentrations that have the ability to move and function distal sites. Hormone homeostasis is critical balance plant growth development regulated multiple levels, including hormone biosynthesis, catabolism, perception, transduction. In addition, over short long distances regulate various developmental processes responses environmental factors. Transporters coordinate these movements, resulting in maxima, gradients, cellular subcellular sinks. Here, we summarize current knowledge most characterized transporters with respect biochemical, physiological, activities. We further discuss localizations transporters, their substrate specificities, need for same context development.

Plant root systems are critical for absorbing water and nutrients anchoring plants in the soil, their development is regulated by phytohormones complex signaling pathways. Recent studies have identified small peptides as essential players governing development, binding to specific receptors on cell membrane, triggering processes. In this study, we summarize recent advances peptide regulation of system architecture tissue organization, well molecular interaction between canonical hormone signaling. Additionally, discuss functions modulating responses environmental forces like nitrogen phosphate starvation, osmotic stress, soil microbes through activation local systemic This review offers a comprehensive overview during plant prospects further crop breeding applications.

Pectin is an abundant cell wall polysaccharide with essential roles in various biological processes. The structural diversity of pectins, along the numerous combinations enzymes responsible for pectin biosynthesis and modification, plays key ensuring specificity plasticity remodeling different types under environmental conditions. This review focuses on recent progress understanding aspects pectin, from its biosynthetic modification processes to types. In particular, we describe findings that modifications serve not only as final outputs internally determined pathways, but also components intercellular communication, a major contributor this process. comprehensive view diverse presented here provides important basis how wall-enclosed plant cells develop, differentiate, interact.

In Arabidopsis, the root clock regulates spacing of lateral organs along primary through oscillating gene expression. The core molecular mechanism that drives periodicity and how it is modified by exogenous cues such as auxin gravity remain unknown. We identified key elements oscillator (AUXIN RESPONSE FACTOR 7, its auxin-sensitive inhibitor IAA18/POTENT, auxin) form a negative regulatory loop circuit in oscillation zone. Through multilevel computer modeling fitted to experimental data, we explain expression oscillations coordinate with cell division growth create periodic pattern organ spacing. Furthermore, gravistimulation experiments based on model predictions show external stimuli can lead entrainment clock. Our work demonstrates underlying robust biological respond stimuli.

Understanding how roots modulate development under varied irrigation or rainfall is crucial for of climate-resilient crops. We established a toolbox tagged rice lines to profile translating mRNAs and chromatin accessibility within specific cell populations. used these study in range environments: plates the lab, controlled greenhouse stress recovery conditions, outdoors paddy. Integration mRNA data resolves regulatory networks following: cycle genes proliferating cells that attenuate DNA synthesis submergence; involved auxin signaling, circadian clock, small RNA regulation ground tissue; suberin biosynthesis, iron transporters, nitrogen assimilation endodermal/exodermal modulated with water availability. By applying systems approach, we identify known candidate driver transcription factors water-deficit responses xylem plasticity. Collectively, this resource will facilitate genetic improvements root optimal climate resilience.

Lateral roots (LRs), are an important component of plant roots, playing a crucial role in anchoring the soil and facilitating uptake water nutrients. As post-embryonic organs, LRs originate from pericycle cells primary root, their formation is characterized by precise regulation cell division complex intercellular interactions, both which closely tied to wall regulation. Considering rapid advances molecular techniques over past three decades, we reframe understanding dynamic change during LR development summarizing factors that precipitate these changes effects, as well regulated signals involved. Additionally, discuss current challenges this field propose potential solutions.

Lateral root formation is coordinated by both endogenous and external factors. As biotic factors, plant growth-promoting rhizobacteria can affect lateral formation, while the regulation mechanism unclear. In this study, applying various marker lines, we found that volatile compounds (VCs) from Bacillus amyloliquefaciens SQR9 induced higher frequency of DR5 oscillation prebranch site accelerated development emergence primordia thus promoted in Arabidopsis. We demonstrated a critical role auxin on B. VCs-induced via respective mutants pharmacological experiments. Our results showed biosynthesis, polar transport signalling pathway are involved roots formation. further acetoin, major component VCs, less active promoting compared to VC blends amyloliquefaciens, indicating presence yet uncharacterized/unknown VCs might contribute effect summary, our study revealed an auxin-dependent regulating branching non-contact manner, efforts will explore useful promote development.

Lateral roots are important to forage for nutrients due their ability increase the uptake area of a root system. Hence, it comes as no surprise that lateral formation is affected by or nutrient starvation, and such contributes system plasticity. Understanding molecular mechanisms regulating adaptation dynamics toward availability useful optimize plant use efficiency. There at present profound, though still evolving, knowledge on pathways. Here, we aimed review intersection with signaling pathways give an update regulation development nutrients, particular focus nitrogen. Remarkably, most not clear how controlled. Only nitrogen, one dominant in control formation, crosstalk multiple key signals determining clearly shown. In this update, first general overview current affect followed deeper discussion nitrogen act different root-mediating which recent studies yield insights.
