Light deficit in shaded environment critically impacts the growth and development of turf plants. Despite this fact, past research has predominantly concentrated on shade avoidance rather than tolerance. To address this, our study examined photosynthetic adjustments Bermudagrass when exposed to varying intensities gain an integrative understanding response C4 turfgrass.

Aims Patterns of leaf trait variation and correlation have long been a key aspect in unraveling plant responses to climate change.However, the specifics how these patterns structural traits photosynthetic physiological characteristics align differ across growth types broadleaf plants remain unclear.Methods This study focused on 18 dominant or common species mixed broadleaf-Korean pine (Pinus koraiensis) forest.We measured four (leaf area (LA), thickness (LT), dry matter content (LDMC) mass per (LMA)) chlorophyll value (SPAD), intercellular CO 2 concentration (C i ), stomatal conductance (G s ) net rate (P n )).We analyzed correlations between different plants.Important findings Leaf functional displayed ranges spanning from 7.73% 74.54%.Interspecific differences accounted for majority variability LA LT, while type primarily drove C , SPAD, LDMC, LMA.G P originate mainly intraspecific differences.There were significant among all traits.Specifically, herbs showed significantly higher LA, compared shrubs trees, trees exhibited elevated LMA, G herbs.There isometric relationships

The Concerted Function of a Novel Class of Transcription Factors, ZBFs, in Light, Jasmonate and Abscisic Acid Signaling Pathways

Journal of Experimental Botany, Год журнала: 2024, Номер 76(3), С. 746 - 768

Abstract Several classes of transcription factors have been investigated in light signaling pathways that bind to the light-responsive elements (LREs) present promoters regulatory genes for transcriptional regulation. Some these shown numerous through genome-wide ChIP-on-chip (ChIP-chip) studies. Furthermore, integration ChIP-seq and RNA-seq techniques, it has demonstrated a factor modifies expression with which interacts. However, mode action their dependency on other regulators pathway just started be unraveled. In this review, we focus particular class factors, ZBFs (Z-box-binding factors), associated partners within same or proteins during photomorphogenesis. Moreover, further made an attempt summarize crosstalk jasmonic acid-, abscisic salicylic acid-mediated defense pathways. This review offers in-depth insight into manner interactors reshape cellular functions plant behavior. The underlying principles not only contribute comprehensive understanding but also establish framework analyzing interplay between early developmental events hormone signaling, regulation orchestrated by ZBF family.

Temporal and spatial frameworks supporting plant responses to vegetation proximity

PLANT PHYSIOLOGY, Год журнала: 2024, Номер 196(3), С. 2048 - 2063

Abstract After the perception of vegetation proximity by phytochrome photoreceptors, shade-avoider plants initiate a set responses known as shade avoidance syndrome (SAS). Shade B (phyB) photoreceptor unleashes PHYTOCHROME INTERACTING FACTORs and initiates SAS responses. In Arabidopsis (Arabidopsis thaliana) seedlings, involves rapid massive changes in gene expression, increases auxin production, promotes hypocotyl elongation. Other components, such phyA ELONGATED HYPOCOTYL 5, also participate regulation elongation response repressing it. However, why how so many regulators with either positive or negative activities modulate same remains unclear. Our physiological, genetic, cellular, transcriptomic analyses showed that (i) these components are organized into 2 main branches modules (ii) connection between them is dynamic time exposure. We propose model for shade-induced which temporal spatial functional importance various analyzed here helps to explain coexistence differentiated regulatory overlapping activities.
