This study focused on optimizing the static assimilation chamber to facilitate automated and long-term acquisition of the net CO₂ exchange rate in individual standing tree, with the entire <i>Radermachera sinica</i> as the research object. Concurrently, we monitored environmental factors and stem water content; Notably, a proprietary stem water content sensor was innovatively employed to capture the internal water dynamics within stem tissue; While the Internet of Things (IoT) technology was leveraged to establish a monitoring system for the net CO₂ exchange rate of individual standing tree. Initially, we conducted an exploratory analysis on the characteristics of the net CO₂ exchange rate by integrating stem water content under distinct watering conditions, and uncovered interplay between plant carbon sequestration capacity and internal water dynamics. Subsequently, machine learning models, including the support vector machine (SVM), backpropagation (BP) neural network, and random forest (RF) algorithms, were developed to predict the net CO₂ exchange rate. The results revealed that under normal watering conditions, the net CO₂ exchange rate exhibited diurnal U-shaped variations, generally transitioning from positive to negative in the morning and vice versa in the evening, with daily carbon sequestration remaining negative. Under drought stress and subsequent rehydration, the net CO₂ exchange rate demonstrated a gradual reduction, followed by disruption, and eventual recovery, resulting in the daily carbon sequestration transitioning from negative to positive, then back to negative. A significant positive correlation was observed between the net CO₂ exchange rate and stem water content change rate; In most cases, positive or zero stem water content change rate corresponded to carbon release, whereas negative change rate indicated carbon absorption. The RF model exhibited superior predictive accuracy, displaying strong agreement between predicted and actual values. Specifically, under normal watering conditions, the RF model achieved Root mean square error (RMSE), coefficient of determination (<i>R</i>²), and mean absolute error (MAE) values of 1.356, 0.8576 and 0.9257%, respectively; Under drought stress and subsequent rehydration, corresponding values were 1.4567, 0.8436, and 1.0258%, respectively.</p>","PeriodicalId":21477,"journal":{"name":"Russian Journal of Plant Physiology","volume":"187 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141513089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to assess the influence of soil amendments (gypsum, GP and humic acid, HA) and vitamin B6 (pyridoxine-HCl), levels on growth, yield traits and bioactive compounds of coriander plants grown in salt-affected soil. GP and HA, whether individual or in combination, at a rate of 500 and 20 kg/ha, respectively, were applied under spraying of B6 at three levels of at 0.0, 150, 300 µM. The experiment was performed in a strip-plot arrangement under randomized complete blocks design using three replications. Findings illustrated the increases in umbels number/plant, umblets number/plant, seed counts/umbels, and seed yield/plant due to applying GP + HA × B6-leafy applied at 300 µM were 150.3, 117.9, 157.4, and 237.8%, respectively. GP + HA mixture with spraying 300 µM B6 possessed the lowest values of H₂O₂ and malondialdehyde (by 1.78 and 0.12 µmol/g FW, orderly), in relative to the control. As well, the highest significant percentages of TSS, SPC, FAA, and FProC were obtained from the combination of GP + HA mixture × 300 µM B6.

The foliar application of NO not only increased the number of leaves produced and the biomass of the shoots under the low EC conditions, but also mitigated the risk associated with the high EC conditions. Higher proline levels were recorded in both the leaves and the roots of plants treated with NO and/or salinity among which the (NO + salinity) group had the highest amount. Both NO and high EC treatments contributed to the reduction of the saponin metabolite concentration. The highest activity of the PAL enzyme was recorded in NO-treated seedlings cultivated under high EC conditions. Total soluble phenolic and flavonoid content exhibited a similar trend to that of the PAL activity in response to the NO treatments under two EC conditions. The NO or saline treatments individually up-regulated the <i>WRKY</i> transcription factor by an average of 4.2-fold, while the NO treatment under the saline medium led to a drastic increase (9.7-fold) in the expression of this gene. The <i>bZIP</i> gene also showed a similar trend as the <i>WRKY</i> transcription factor gene.

In sensitive genotype, cold stress increased H₂O₂ and MDA contents by 47 and 57%, respectively, without any significant changes in tolerant genotype.

During the initial stages of cold responses, ABA content in tolerant genotype reached its peak, showing 77% increase 3 days post stress (dps), whereas the sensitive genotype showed 20% raise 6 dps. Gibberellin (GA) content in the tolerant genotype was 16% higher than the sensitive genotype 1 dps. Compared to control conditions, indole acetic acid (IAA) content attained its maximum level in tolerant and sensitive genotypes at 1 and 6 dps, respectively. 15% increase in phenol compoundsin tolerant genotype was concomitant with heightened antioxidant capacity, as well as increased in flavonoid and anthocyanin contents by 46, 75 and 200% respectively. At 6 dps, a significant increase in transcript levels of chalcone synthase (15.3-fold), phenylalanine ammonia-lyase (3.5-fold), and <i>DELLA</i> (4.2-fold) genes were observed in tolerant genotype at 6 dps.

Understanding how plants adapt to drought conditions is crucial for developing drought-resistant crop varieties. Plants have been gifted with adaptation capacity to cope with situations arising from water deficit. Their capacity to acclimate is featured by adaptive changes in plants. The capacity to capture changes in shoot architecture has now been enhanced by the advent of non-invasive phenotyping techniques involving various imaging systems in plant phenomics platforms. These platforms thrive on the assumption that the plant responses reflected in terms of changes in the structure of the plant that can offer ample scope to employ machine vision for differentiating the responses of plants to soil-moisture deficit. Further, it is assumed that the detectable genetic variation in morphological traits responding to soil moisture deficit can provide hints about a plant’s tolerance to stress and can be exploited to improve crop productivity in drought-prone areas. Genomic interventions utilizing high throughput phenotyping, make the selection of drought-tolerant genotypes easier. In recent years, machine vision has emerged as a powerful tool to study and quantify plant responses to drought stress. This article reviews the current state of knowledge on drought-adaptive responses in plants and explores the potential of genomic-assisted breeding tools coupled with high-throughput phenotyping platforms and machine vision to accelerate the elucidation of genotypic differences in adaptive traits.
