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.

ABSTRACT AUXIN RESPONSE FACTOR 7 (ARF7)‐mediated auxin signaling plays a key role in lateral root (LR) development by regulating downstream LATERAL ORGAN BOUNDARIES DOMAIN ( LBD ) transcription factor genes, including LBD16 , LBD18 and LBD29 . proteins are believed to regulate the of genes as homodimers or heterodimers. However, whether forms dimers with other LR remains unknown. Here, we determined that Arabidopsis thaliana (L.) Heynh. MYB factors MYB2 MYB108 interact auxin‐induced development. Both were induced an ARF7‐dependent manner. Disruption fusion SRDX domain severely affected formation ability induce By contrast, overexpression resulted greater numbers, except lbd29 mutant background. These findings underscore interdependence importance MYB2, MYB108, In addition, MYB2–LBD29 MYB108–LBD29 complexes promoted expression CUTICLE DESTRUCTING 1 CDEF1 ), member GDSL (Gly‐Asp‐Ser‐Leu) lipase/esterase family involved summary, this study identified regulatory modules act ARF7 intricately control auxin‐mediated

The plant root is an important storage organ that stores indole-3-acetic acid (IAA) from the apical meristem, as well nitrogen, which obtained external environment. IAA and nitrogen act signaling molecules promote growth to obtain further resources. Fluctuations in distribution of soil environment induce plants develop a set strategies effectively improve use efficiency. Auxin integrates information regarding nitrate status inside outside body reasonably distribute resources sustainably construct system. In this review, we focus on main factors involved process nitrate- auxin-mediated regulation structure better understand how system internal utilized modify architecture.

Abstract Rhizosphere microorganisms interact with plant roots by producing chemical signals that regulate root development. However, the distinct bioactive compounds and signal transduction pathways remain to be identified. Here, we showed sesquiterpenes are main volatile produced plant‐beneficial Trichoderma guizhouense NJAU4742. Inhibition of sesquiterpene biosynthesis eliminated promoting effect this strain on growth, indicating its involvement in plant‐fungus cross‐kingdom signalling. Sesquiterpene component analysis identified cedrene, a highly abundant NJAU4742, stimulate growth Genetic auxin transport inhibition TIR1 AFB2 receptors, IAA14 auxin‐responsive protein, ARF7 ARF19 transcription factors affected response lateral cedrene. Moreover, AUX1 influx carrier PIN2 efflux were also found indispensable for cedrene‐induced formation. Confocal imaging cedrene expression pPIN2:PIN2:GFP pPIN3:PIN3:GFP, which might related morphology. These results suggested novel molecule from T. regulates development through signalling auxin.

Abstract Asymmetric cell division (ACD) is a fundamental process that generates new types during development in eukaryotic species. In plant development, post‐embryonic organogenesis driven by ACD universal and more important than animals, which organ pattern preset embryogenesis. Thus, provides powerful system to study molecular mechanisms underlying ACD. During the past decade, tremendous progress has been made our understanding of key components involved this plants. Here, we present an overview how determined regulated multiple biological processes compare their conservation specificity among different model systems. We also summarize roles phytohormones regulation Finally, conclude with overarching paradigms principles govern consider technologies can be exploited fill knowledge gaps make advances field.

The crucial role of TIR1-receptor-mediated gene transcription regulation in auxin signaling has long been established. In recent years, the significant protein phosphorylation modifications signal transduction gradually emerged. To further elucidate signaling, a phosphoproteomic analysis conjunction with treatment identified an activated Mitogen-activated Protein Kinase (MAPKKK) VH1-INTERACTING (VIK), which plays important auxin-induced lateral root (LR) development. vik mutant, LR development is significantly attenuated. Further investigations show that VIK interacts separately positive regulator development, LATERAL ORGAN BOUNDARIES-DOMAIN18 (LBD18), and negative emergence, Ethylene Responsive Factor 13 (ERF13). directly phosphorylates stabilizes factor LBD18 formation. meantime, ERF13 at Ser168 Ser172 sites, causing its degradation releasing repression by on emergence. summary, VIK-mediated regulates enhancing stability inducing ERF13, respectively.

Abstract Cadmium (Cd) strongly inhibits root growth, especially the formation of lateral roots (LRs). The mechanism Cd inhibition on LR in rice (Oryza sativa) remains unclear. In this study, we found that emergence was inhibited significantly by 1 �M and almost completely arrested 5 Cd. suppressed both subsequent development primordium (LRP). By using transgenic expressing auxin response reporters DR5::GUS DR5rev::VENUS, markedly reduced levels stele LRP. rapidly downregulated expression efflux transporter genes OsPIN1b, OsPIN1c OsPIN9 LRs a cultivar with null allele OsHMA3 (Heavy Metal ATPase 3) more sensitive to than cultivars functional alleles. Overexpression greatly alleviated inhibitory effect Cd, but protective abolished polar transport inhibitor 1-N-naphthylphthalamic acid. results suggest disrupting OsPIN-mediated distribution LRP protects against toxicity sequestering into vacuoles.

Both auxin signalling and programmed cell death (PCD) are essential components of a normally functioning plant. Auxin underpins plant growth development, as well regulating defences against environmental stresses. PCD, genetically controlled pathway for selective elimination redundant, damaged or infected cells, is also key element many developmental processes stress response mechanisms in plants. An increasing body evidence suggests that PCD regulation often connected. While generally appears to suppress death, it has been shown promote events, most likely via stimulation ethylene biosynthesis. Intriguingly, certain cells undergoing have suggested control the distribution tissues, by either releasing burst creating an anatomical barrier transport distribution. These recent findings indicate novel roles localized events context development such root architecture, tissue regeneration following injury, suggest exciting possibilities incorporation this knowledge into crop improvement strategies.
