Summary: The effects of night interruption light (NIL) provided by light-emitting diodes (LEDs) on the morphogenesis, blooming, and transcription of photoreceptor genes in Petunia hybrida Hort. Easy Wave Pink were investigated. The photoperiod had impacts on both morphogenesis and blooming, and the second NIL had a significant influence on both.

Summary: This study characterizes the involvement of OsiCRY2 in light-regulated plant development, including its role in regulating photomorphogenesis, plant height, and flowering. The over-expression of OsiCRY2 in transgenic plants led to shorter coleoptiles and dwarfism under blue light, white, and far-red light. Interestingly, even the dark-grown transgenic plants exhibited shorter height and higher OsiCRY2 protein levels compared to the wild-type. Transcriptome analysis revealed the differential up-regulation of several light-regulated genes in dark-grown coleoptiles.

Summary: Transcription factors are important in regulating plant responses to environmental changes. Fluctuations in necessary resources such as light, temperature, and water lead to gene reprogramming. Phytochrome-Interacting Factors (PIFs) are key transcription factors that regulate both developmental and external stimuli-based plant growth. This review focuses on identifying PIFs in various organisms, their regulation by different proteins, and their functions in diverse developmental pathways and external stimuli-induced plant responses. Recent advances in characterizing PIFs in crops like rice, maize, and tomato are also discussed, highlighting their potential as key regulators for enhancing agronomic traits.

Summary: This study provides a comprehensive analysis of the GA oxidase gene family in rice. The genes were divided into four subgroups and shared some common features with GAox genes in Arabidopsis. Tissue-specific expression patterns were observed for each GAox gene, and some genes may play a major role in regulating the level of bioactive GA.

Summary: The study revealed that gibberellin and brassinosteroid synergistically regulate seed germination and post-germination growth in rice. Both hormones induced the expression of glutelin proteins and encoding genes, promoting glutelin mobilization and degradation to facilitate the germination process and embryo growth.

Summary: This study reveals the regulatory mechanism of two auxin response factors, OsARF6 and OsARF17, in controlling flag leaf angle in rice. They activate the expression of the ILA1 gene to determine leaf angle, providing new breeding targets for this key trait in rice and potentially other cereals.

Summary: Leaf morphology is an important trait for plant architecture and stress resistance. In this study, a rice mutant, ltr1, with rumpled leaves and decreased grain yield was identified. LTR1, a wax synthesis gene, was found to be constitutively expressed in various tissues, with higher expression in leaves and panicles. Overexpression of LTR1 increased grain yield and positively regulated salt stress by affecting water and ion homeostasis. These findings provide insights into the molecular mechanisms of leaf morphogenesis and stress response, and offer a potential strategy for stress-tolerance breeding.

Summary: This study compares the transcriptome differences between tolerant and susceptible rice cultivars to reveal the molecular mechanisms of sheath blight resistance. Significant differences in gene expression were observed between the tolerant and susceptible cultivars in response to Rhizoctonia solani invasion, involving cell surface pattern recognition receptors, signaling pathways, and photosynthetic capacity. These findings are crucial for a better understanding of the mechanisms behind sheath blight resistance and the development of resistant cultivars through molecular breeding methods.

Summary: Due to labor shortages or resource scarcity, direct seeding is the preferred method for rice cultivation. This study identified the genes involved in shade-avoidance syndrome by comparing two density of direct seeding (high and normal density). The results showed that high density direct seeding causes constitutive shade-avoidance syndrome, leading to early flowering and changes in plant architecture. Additionally, high density direct seeding downregulates the expression of chloroplast synthesis-related genes, causing senescence. These findings suggest that high density direct seeding can be utilized to breed density-tolerant rice varieties more easily and widely.

Summary: Moderate leaf rolling is important for improving photosynthetic efficiency and grain yield in rice. This study identified a mutant with adaxially rolled leaves, which was caused by a mutation in OsDRB2 gene. The mutation affected the accumulation of miRNAs and the expression of related genes, leading to abnormal leaf development.

Summary: As summer approaches, plants experience enhanced light inputs and warm temperatures, resulting in opposite morphogenic impacts. A mathematical model incorporating the known interactions of regulators PHYTOCHROME B (phyB), EARLY FLOWERING 3 (ELF3), and CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) accurately predicts and recapitulates the thermal growth of different plant lines. The study reveals that COP1 acts at temperature signaling only during daytime and plays an essential role in conveying the thermosensory function of phyB and ELF3. This thermal model could help identify the best allelic combinations to enhance climate change resilience in different latitude crops.

Summary: In Arabidopsis, the SPA2 protein functions as a suppressor of photomorphogenesis under different light conditions. The central coiled-coil and C-terminal WD-repeat domains of SPA2 play a critical role in repressing seedling de-etiolation, cotyledon unfolding, and promoting hypocotyl negative gravitropism. Light-activated phyA, phyB, cry1, and COP1 interact directly with SPA2 to rapidly suppress its activity in response to far-red, red, and blue light treatments.

Summary: Plant height is an important agronomic trait of rice and is closely related to yield. This study found that the miR528-D3 module negatively regulates plant height in rice by modulating the balance of GA and ABA, thereby affecting internode elongation.

Summary: This study developed a new algorithm, TEF, which can detect transposable elements (TEs) with unknown sequences and determine the sequences of both ends and the insertion positions of transposed TEs by directly comparing the NGS data. This method verifies the genotypes of transpositions by counting the junctions of head and tail, and non-insertion sequences in NGS reads. It is easy to use and independent of any TE library, making it useful for detecting insertions from unknown TEs bypassed by common TE annotation pipelines.

Summary: In Arabidopsis thaliana, the mutation in the GNOM gene severely inhibits lateral root (LR) formation, while the fewer roots suppressor1 (fsp1) mutation partially restores LR formation. It has been found that fsp1 mutation increases endogenous IAA levels and the number of sites where auxin response accumulates before LR formation, and SUR2 gene affects IAA accumulation in the pericycle cells at the xylem pole.
