Summary: The morpho-anatomical and physiological characteristics of cryo-derived pineapple plants after acclimatization were studied. The plants showed similar morphological development to conventionally micropropagated and non-cryopreserved plants. The pineapple plantlets developed efficient anatomical leaf structures to adapt to the transition from in vitro to ex vitro.

Summary: Pineapple is a popular tropical fruit that contains many volatile organic compounds. Among the identified 480 VOCs, only 40 compounds contribute to its unique flavor. Currently, there is no consolidated database of pineapple VOCs and aroma compounds. This review summarizes the analytical methodologies, volatile profiles, and characteristic aroma compounds of different pineapple varieties at different maturities, providing a subset of key pineapple aroma volatiles for further research or varietal improvement.

Summary: A biochemical model integrated with 3-D shoot morphology was developed to simulate CAM plant productivity, and it successfully predicted the carbon uptake of Agave tequilana over daily and annual courses. The theoretical energy conversion efficiency of Agave spp. was found to be up to 7% higher than for C-3 photosynthesis, but the actual productivity was influenced by light interception, biochemical and anatomical limitations. However, it still demonstrated the potential of CAM plants in climates with limited crop options.

Summary: This study aimed to determine the free and glycosidically bound volatile compounds in Okinawan pineapple cultivars. The results showed that the content and composition of free volatile components varied among the different cultivars, and hydroxyl-group compounds in glycosidic form could be released through enzymatic hydrolysis. Two glycosides were identified in all cultivars, which could potentially contribute to the medicinal-herbal aromas.

Summary: In this study, bioinformatics was used to confirm the differential expression of the GA2 gibberellin oxidase gene AcGA2oxs in the pineapple genome, and 42 AcGA2ox genes were identified and divided into four groups. The gene structure, conserved motifs, and chromosome localization of AcGA2oxs were analyzed. The expression profile of AcGA2oxs in different tissue parts was analyzed, and the relative expression levels of AcGA2ox genes were upregulated under GA3 treatment. These findings provide valuable information for further understanding the evolution and function of the GA2ox family in pineapple.

Summary: This study introduces a multispectral imaging-based approach to provide distribution maps of moisture content, soluble solids content, and carotenoids content in fresh-cut pineapple. Calibration models with selected wavelengths were established to predict the chemical composition of each pixel of the multispectral images, enabling spatially distributed quantification of the fruit slice. This approach can be applied in the mechanized preparation of fresh-cut produce.

Summary: The responsiveness of miscanthus and switchgrass to nitrogen fertilizer and stand age varies, with decreasing rates of increase. The addition of nitrogen fertilizer significantly increases yield, but with a small and varying response level depending on the age of the crop. Miscanthus shows a larger response to nitrogen in middle-aged stands, while switchgrass responds more to nitrogen in younger and older stands. Soil productivity does not have a significant effect on yield for either crop.

Summary: The growing population and increased standard of living globally lead to a higher demand for plant-derived products. Plant-based research will play a crucial role in ensuring food security and expanding the bio-based economy. Crop productivity depends on various factors, including resources, management, and intrinsic yield potential. This review focuses on the determinants of intrinsic yield potential to maximize plant potential in food and energy production. Many complex traits and processes can be targeted to increase crop yield, at the cellular, organ, and canopy level.

The study found considerable diversity in yield and yield-component traits among and within genetic groups of M. sacchariflorus. The Yangtze 2x genetic group showed the highest biomass yield potential.

Summary: We have shown that speeding up the relaxation of nonphotochemical quenching can increase soybean photosynthetic efficiency and yield. In response, Sinclair et al. claim that improving photosynthesis cannot enhance crop yields and that there is only one valid experimental design to prove genetic improvement in yield. We address the flaws in both of these assertions.

Summary: Efforts are being made to bioengineer nitrogen fixation into nonleguminous crops, requiring a quantitative understanding of its energetic costs and the relationship between metabolic variations and symbiotic efficiency. A whole-plant metabolic model for soybean with its associated microsymbiont was developed and used to predict the cost-benefit of nitrogen fixation under different soil nitrogen availability. The model predicted a nitrogen-fixation cost of approximately 4.13 g C g(-1) N and a grain yield reduction of 27%, compared to non-nodulating plants receiving their nitrogen from the soil.

Summary: Improving photosynthetic efficiency by manipulating chloroplast size is unlikely to be a viable approach as increasing chloroplast size decreases efficiency and productivity. However, reducing chloroplast size can maintain similar efficiency compared to wild-type plants. Therefore, it is not feasible to manipulate chloroplast size to improve photosynthetic performance.

Summary: Cowpea is the major source of vegetable protein for rural populations in sub-Saharan Africa. The speed of photosynthetic adjustment to shade strongly affects daily carbon gain. Direct biochemical measurements showed a faster rate of Rubisco deactivation in cowpea than previously estimated. This suggests that slowing Rubisco deactivation during shade is an unexploited opportunity for improving crop productivity.
