Summary: Root system architecture (RSA) and tiller development in rice are regulated by the IGT family genes, which are influenced by the genetic background of the rice and different environmental conditions. The study found a positive correlation between RSA (including root width, length, and area) and tiller number, and observed different expression patterns of IGT family genes under irrigation and drought conditions.

Summary: Plant growth and development are closely related to environmental stress defense mechanisms. Programmed cell death (PCD) is a genetically controlled pathway for selectively eliminating redundant, damaged, or infected cells. Evidence suggests that auxin signaling and PCD regulation are often interconnected, with auxin generally suppressing cell death but also promoting PCD events in certain circumstances.

Summary: Line-spacing shrinkage and row-spacing expansion (LSRE) is an important type of interplant competition that can increase tiller number and resource utilization efficiency in wheat. This study evaluated the tillering characteristics, phytohormone content, and grain yield factors of winter wheat under LSRE treatment. LSRE significantly promoted tillering and biomass at the pre-winter stage, and the changes in phytohormone levels were responsible for the tillering process. LSRE treatment improved crop yield by increasing the number of spikes per unit area and grain weight.

Summary: Roots play crucial roles in plant growth by anchoring and absorbing water and nutrients. Root evolution occurred independently at least twice in lycophyte and euphyllophyte clades, with the control mechanisms of root development in lycophytes remaining unclear.

Summary: Nitrogen is a critical nutrient for wheat growth, but excessive use of nitrogen fertilizers can lead to environmental pollution. Research has shown that wheat plants can adapt to nitrogen starvation through signaling mechanisms and optimizing root system architecture.

Summary: The study revealed that the heavy fruitlet abscission was attributed to malformed pollen structure and low viability. Abscising fruits and carpopodium showed red coloration and aborted embryos, mainly due to low pollen viability and malformation. Transcriptome analysis identified numerous differentially expressed genes, including those related to plant hormone biosynthesis and signal transduction, as well as cell wall remodeling, indicating their crucial roles in regulating the abscission process.

Summary: This study investigated the root morphological traits and changes in phytohormones of allelopathic and non-allelopathic rice cultivars when co-planted with herbicide-resistant barnyard grass. The results showed that the allelopathic rice had greater shoot and root biomass and exhibited better root morphology compared to other rice cultivars. Additionally, the allelopathic rice responded positively to the stress of herbicide-resistant barnyard grass, with changes in phytohormonal content.

Summary: Plants rely on a diverse range of metabolites to control growth and development, and to overcome stress. Karrikins (KARs) are a class of butenolide compounds found in smoke that stimulate seed germination and regulate various developmental processes in plants. KARs are perceived via a plant alpha/beta-hydrolase called KARRIKIN INSENSITIVE2 (KAI2), which also functions as a receptor for a postulated phytohormone, provisionally termed KAI2 ligand (KL).
