Summary: This article comments on the research done by Zhang et al. They identified ZmWRKY28 as a key regulatory element in the shade avoidance response (SAR) of maize, and explored its light-dependent pathway regulation. This discovery provides a potential new target for improving maize yield.

Summary: Shade-avoiding plants can adjust their responses based on the presence of neighboring vegetation. This response is regulated by the phytochrome B photoreceptor, which becomes inactive in environments with low red to far-red light ratios. In deep canopy shade, plants can suppress stem elongation to counteract shade avoidance and promote survival.

Summary: The article discusses how plants respond to shade, classifying them into shade avoiding and shade tolerance plants. Shade avoiding plants induce shade avoidance responses (SARs) to outgrow competitors, while shade tolerance plants induce shade tolerance responses (STRs) to enhance survival rates.

Summary: Plants detect and respond to the proximity of competitors using light signals perceived by photoreceptor proteins. Different photoreceptors help plants optimize their developmental configuration and resource allocation patterns in the canopy by controlling major regulatory nodes for growth and development. Understanding these mechanisms is important for breeding programs and manipulating light environments in agriculture.

Summary: By constructing hyperactive mutated alleles ZmPHYB1(Y98F) and ZmPHYB1(Y359F), this study demonstrates their utility in attenuating shade avoidance syndrome (SAS) and breeding high density-tolerant varieties of maize, which is crucial for increasing the planting density and yield of maize.

Summary: In this study, the roles of two COP1 homologous genes, GmCOP1a and GmCOP1b, were investigated in soybean. It was found that GmCOP1b plays a more prominent role in promoting stem elongation under normal light conditions. Additionally, GmCOP1b mutants exhibited reduced shade response and performed better under high-density conditions in field trials.

Summary: The maize cryptochrome 1b plays a crucial role in seedling de-etiolation and integrates light signals with the gibberellin metabolic pathway in maize, resulting in decreased plant height and enhanced lodging resistance.

Summary: The study reveals that the HFR1 protein in Cardamine hirsuta is more stable than in Arabidopsis thaliana, likely due to its lower binding affinity to COP1, enhancing its biological activity. This leads to a different balance of the PIF-HFR1 module in C. hirsuta, reducing PIF activity and attenuating other PIF-mediated responses.

Summary: Plants can sense light signals through specific photoreceptors, and the light spectrum plays a crucial role in the response of plants to light intensity under biophilic illumination.

Summary: Plants compete for sunlight and have evolved to perceive shade through both relative increases in far-red photons and decreases in total photon flux. The interaction between far-red fraction and total photon flux influences leaf expansion, favoring stem elongation and biomass partitioning to stems at low light intensities but promoting leaf expansion at high light intensities.

Summary: The phytochrome B (phyB) serves as a light and temperature sensor in the seasonally synchronized growth cycle of perennial plants. PHYB genes and their downstream PHYTOCHROME INTERACTING FACTOR (PIF) targets play different roles in regulating tree growth and shade avoidance. The PHYB-PIF8 regulon controls seasonal growth, while phyB coordinately regulates shade avoidance responses and seasonal growth cessation in Populus trees.

Summary: Shade avoidance syndrome (SAS) is an adaptive strategy that involves elongation of the stem and petiole, leaf hyponasty, and altered phototropic orientation in response to reduced blue light and low red:far-red ratio. BBX24 and JAZ3 are key regulators in the SAS pathway, jointly controlling DELLA activity and plant growth.

Summary: Strong wind inhibits plant growth by decreasing net assimilation rate and leaf area ratio, but this effect can be mitigated by far-red light, which reduces the negative impact of wind on plant growth.

Summary: Shade avoidance syndrome (SAS) is important for plants to increase light capture in dense stands, but the genetic basis of developmental variation in leaves related to leaf area, petiole length, and leaf length remains unresolved.

Summary: The rice phytochrome A mutant (phyA) shows poor growth and decreased photosynthesis under both low and normal light conditions, mainly due to the weaker function of phyA. The chlorophyll content, photosynthetic capacity, and yield of phyA mutants decrease more significantly than WT plants under low light conditions.
