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: This study investigated the QTL-by-QTL, QTL-by-environment, and QTL-by-QTL-by-environment interactions by targeting four loci controlling grain length in rice. Through the development of near-isogenic lines with different genetic combinations and the analysis using linear models and interaction principal component analysis, the variations of additive effects, QQ effects, and environmental effects were estimated. The results showed differential responses of QQ effects to different environments, as well as differences between QQ effects including the long-grain allele at LKF and those excluding this allele.

Summary: This study investigates the global distribution of the fraction of leaf nitrogen allocated to RuBisCO, finding that it is largely influenced by leaf thickness and phosphorus content. Regional variations in fLNR are also driven by factors such as light intensity, atmospheric dryness, soil pH, and sand. The research provides insights into the nitrogen-photosynthesis relationship and enhances our understanding of photosynthetic potential on a global scale.

Summary: In this study, a small look-up table (LUT) for leaf area index (LAI) inversion of rice fields was developed using the vegetation isoline pattern and consideration of vegetation cover fraction (fCover). The accuracy of the inversed LAIs was improved by including fCover in the LUT, as shown in comparisons with LUTs without fCover consideration. The proposed method has the potential to produce high spatial resolution LAI maps for crops and assist in the validation of moderate-resolution LAI products and agricultural monitoring.

Summary: This study identified candidate genes responsible for allelopathic interactions between rice and barnyardgrass through transcriptome analysis. The results showed a quick allelopathic response in rice within 3 hours. Comparison of differentially expressed genes (DEGs) between rice and barnyardgrass revealed different mechanisms underlying allelopathic interaction in these two species.

Summary: The altitudinal gradient plays a crucial role in the variation of leaf traits. This study examined the leaf traits of woody species at different altitudes in the eastern Qinghai-Tibet Plateau. The results showed that leaf dry weight increased with elevation, while leaf fresh weight and leaf area exhibited a unimodal change. The scaling exponent of leaf area and leaf fresh weight (or dry weight) was significantly greater than 1, indicating increasing returns for pooled data.

Summary: Leaf anatomy in trees acclimates to light and hydraulic gradients within the crown. Phenotypic plasticity of leaf traits is larger than genetic variation in Fagus crenata, with leaf mass per area (LMA) increasing with height due to both light and hydraulic limitations. Leaf thickness is mainly driven by light availability, while thicker leaves also adapt to low water availability. Among the traits, mesophyll porosity has the highest intra-crown plasticity. Individual-level acclimation in F. crenata with high phenotypic plasticity may buffer negative effects of future climate change.

Summary: Moderate leaf rolling in rice is considered optimal for improving photosynthetic efficiency and grain yield. In this study, three stable rice QTLs controlling adaxial leaf rolling were identified using high-density SNP markers, leading to a wide variation in the degree of leaf rolling. Fine mapping showed that qARO1 and qARO9 are located in approximately 60- and 90-kb intervals on chromosomes 1 and 9, respectively.

Summary: The relationship between leaf anatomy and LMA varies with slope aspect, likely due to differences in solar radiation, air temperature, soil water, and nutrient availabilities.

Summary: This study quantified intraspecific trait variation (ITV) in nine leaf functional traits among six disease-resistant cacao clones grown in different environments using bivariate, multivariate, and functional trait space analyses. The results showed that leaf traits varied among clones, with larger physiological trait differences at the mild dry season site and wider chemical trait differences at the harsh dry season site. Multivariate and hypervolume trait space analyses revealed greater site influence on trait values of the least productive clones, supporting the importance of functional trait-based research in plant breeding paradigms.

Summary: The transcription activation activity of ROC8 and ROC5 was demonstrated in regulating rice leaf rolling. The heterodimer form of ROC8 and ROC5 was found to be more functional than their homodimer forms in controlling leaf rolling. The dimerization of ROC members plays a crucial role in regulating leaf rolling in rice.

Summary: Stomatal morphology plays an important role in regulating leaf gas exchange and photosynthetic efficiency under fluctuating light conditions. Smaller and denser stomata lead to faster stomatal response to light fluctuations but lower intrinsic water use efficiency. Stomatal morphology has less impact on stomatal conductance, and there is minimal correlation between steady-state and non-steady-state stomatal conductance among different genotypes. These findings highlight the significance of stomatal morphology in optimizing photosynthetic efficiency and plant growth under fluctuating light.

Summary: Leaf canopy dynamics play a crucial role in crop productivity, and quantifying leaf area growth characteristics with a plant canopy analyzer and mathematical model can help understand the relationship between leaf area growth parameters and rice productivity. Variations in these parameters among rice cultivars, as well as differences in leaf nitrogen content, impact crop productivity and yield predictions. Ultimately, non-destructive measurements and parameterization provide an efficient method for monitoring crop growth and estimating productivity in field experiments.
