Summary: In Arabidopsis thaliana, the genes CONSTANS (CO) and FLOWERING LOCUS C (FLC) play crucial roles in perceiving photoperiod and vernalization, and regulate FLOWERING LOCUS T (FT) to affect flowering time. Research has shown that FT is only expressed at low FLC levels, and the interactions among these three genes can influence flowering time in genetically distinct accessions of Arabidopsis.

Summary: Plants have evolved intricate signaling pathways to perceive and respond to temperature, unlike animals who can avoid unfavorable conditions. While general acclimation processes occur throughout the whole plant, specific temperature responses are limited to certain tissues or cell types. Epigenomic analyses have been successful in understanding global responses, but more localized responses pose challenges due to inaccessibility of relevant chromatin. More research with higher spatiotemporal resolution is needed for future analyses.

Summary: Transparent plastic films with limited light transmittance in greenhouses affect photosynthesis in vegetable crops. This study investigates the effects of different monochromatic lights (red, green, blue) on the growth and morphogenesis of pepper plants. Red and blue lights have opposite roles in determining various plant traits, while green light treatment results in taller plants with fewer branches. The study also identifies a light response factor, HY5, that regulates blue light-induced growth and development in pepper plants.

Summary: The study found that sensing neighboring plants through the Red to Far-Red light ratio (R:FR) can limit yield potential in wheat. The effects of increased R:FR within the canopy were studied in dense wheat mini canopies grown in controlled environments. The response to high R:FR depended on the developmental stage and cultivar, showing positive effects if applied after stem elongation but negative or null effects if applied before. Combining high R:FR with elevated CO2 or CO2 alone also had cultivar-dependent effects. These findings suggest that R:FR plays a significant role in controlling yield potential in wheat.

Summary: FT-like genes play a crucial role in regulating flowering time in angiosperm plants. In barley, the HvFT4 gene specifically delays flowering time and suppresses reproductive development, impacting spikelet formation and grain yield. Understanding the genetic basis of FT-like genes can lead to novel breeding strategies for improving barley productivity.

Summary: A comprehensive study was conducted on Ma bamboo to understand the molecular regulatory mechanism of bamboo flowering. The results identified differentially expressed genes related to the flowering pathway, with DlFT1 being a candidate gene that promotes flowering in bamboo. These findings provide a better understanding of the roles of florigen genes in bamboo and have implications for regulating bamboo flowering in the future.

Summary: In this study, the effect of additional far-red light (FR) during cultivation at two temperatures on postharvest chilling tolerance in basil was investigated. The results showed that additional FR improved the chilling tolerance in basil during storage. Cultivation temperature had no effect on postharvest chilling tolerance. The increase in soluble sugars and starch under additional FR may contribute to the positive effect on chilling tolerance in basil.

Summary: BBX17, a member of the B-box (BBX) family, acts as a repressor of floral transition under long-day conditions. It interacts with CONSTANS (CO) and represses its ability to control FT expression, leading to delayed flowering phenotype in plants overexpressing BBX17. Additionally, the degradation of BBX17 is regulated by light and requires COP1 and 26S proteasome, making it a key factor in controlling flowering in Arabidopsis thaliana.

Summary: This study identified and characterized a cacao candidate florigen gene, TcFLOWERING LOCUS T (TcFT), demonstrating its key role in regulating flowering time in cacao plants. Additionally, overexpression of AtFT in cacao tissues resulted in the formation of flowers in tissue culture, providing further evidence of the highly conserved function of FT in controlling flowering.

Summary: Soil salinity inhibits leaf photosynthesis and agricultural production. The red to far-red light ratio (R/FR) affects leaf photosynthesis under salt stress, but the regulation mechanism is unknown. This study investigated the effects of different R/FR on plant growth, gas exchange parameters, photosynthetic electron transport, Calvin cycle, and gene expression under salt stress. Low R/FR effectively alleviated the negative effects of salt stress on leaf photosynthesis by promoting photosynthetic electron transport and Calvin cycle in cucumber plants.
