Monitoring agricultural drought using remote sensing data is crucial for precision irrigation in modern agriculture. Utilizing unmanned aerial vehicle (UAV) sensing, this study explored the applicability of an empirical crop water stress index (CWSI) based on canopy temperature and three-dimensional indices (TDDI) constructed from surface (Ts), air (Ta) five vegetation (VIs) monitoring moisture status dryland crops. Three machine learning algorithms (random forest regression [RFR], support...

NRAMP family genes participate in the absorption and transport of heavy metals such as cadmium (Cd), zinc (Zn), copper (Cu), lead (Pb), iron (Fe) manganese (Mn) play an important role response to metal stress. There is abundance research on these bacteria, plants fungi, although not S. tuberosum. A total 48 members(potato(5), Arabidopsis(7), Tomato(9), pepper(9), rice(12) tobacco(6)) were identified from 6 species (potato (Solanum tuberosum), Arabidopsis thaliana, Tomato lycopersicum),...

Plants have evolved a number of defense and adaptation responses to protect themselves against challenging environmental stresses. Genes containing heavy metal associated (HMA) domain are required for the spatiotemporal transportation ions that bind with various enzymes co-factors within cell. To uncover underlying mechanisms mediated by StHMA genes, we identified 36 gene members in family divided them into six subfamilies phylogenetic analysis. The StHMAs had high collinearity were...

A genome-wide identification and expression analysis of multidrug toxic compound extrusion (MATE) gene family in potato was carried out to explore the response MATE proteins heavy meta stress. In this study, we identified 64 genes from genome, which are located on 12 chromosomes, divided into I–IV subfamilies based phylogenetic analysis. According their order appearance they were named StMATE1–64 . Subcellular location prediction showed that 98% them plasma membrane as transporters. Synteny...

Abstract Cadmium (Cd) pollution is a serious threat to food safety and human health. Minimizing Cd uptake enhancing tolerance in plants are vital improve crop yield reduce hazardous effects humans. In this study, we designed three concentration stress treatments (Cd1: 0.20 mg·kg −1 , Cd2: 0.60 Cd3: 1.60 ) two foliar silicon (Si) (CK: no spraying of any material, Si: Si spraying) conduct pot experiments on soil stress. The results showed that the leaves reduced content brown rice by...

Monitoring sorghum during the flowering stage is essential for effective fertilization management and improving yield quality, with spike identification serving as core component of this process. Factors such varying heights weather conditions significantly influence accuracy detection models, few comparative studies exist on model performance under different conditions. YOLO (You Only Look Once) a deep learning object algorithm. In research, images were captured at two (15 m 30 m) in 2023...

Carbonate rock dissolution (CRD) in karst areas generates abundant ions, which contribute significantly to nitrogen (N) transformation paddy ecosystems. However, little is known about the microbial mechanisms by CRD ions (Ca2+, Mg2+, HCO3−/CO32−, and OH-) regulate N balance. In this experiment, rice pot studies were conducted using soil (S1), with removed carbonate minerals (S2), non-karst (S3), additional (S4). The effects of on N-metabolizing microorganisms functional genes metabolism...

Understanding the rhizosphere soil microbial community and its relationship with bulk is critical for maintaining health fertility improving crop yields in Karst regions. The communities soils of a Chinese cabbage ( Brassica campestris ) plantation region, as well their relationships nutrients, were examined this study using high-throughput sequencing technologies 16S ITS amplicons. aim was to provide theoretical insights into healthy cultivation area. findings revealed that showed higher...

Landscape ecological risk assessment and network construction are of great significance for optimizing territorial functions reducing regional risks. Based on the production-living-ecological space perspective, this study evaluated spatiotemporal differentiation characteristics landscape its driving mechanism in Southwest China constructed a network. The results showed that proportions space, production living to total 2020 were 74.35%, 24.55% 1.10%, respectively. industrial had highest...

To study the synergistic effects of water management and silicon (Si) foliar spraying on uptake transport cadmium (Cd) in rice, we designed four treatments: conventional intermittent flooding + no Si (CK), continuous throughout growth stage (W), (WSi). The results show that WSi treatment reduced translocation Cd by rice significantly brown content, with effect yield. Compared CK, increased net photosynthetic rate (Pn), stomatal conductance (Gs) transpiration (Tr) 6.5-9.4%, 10.0-16.6%...

Ensuring the safe production of food and oil crops in soils with elevated cadmium (Cd) content karst regions is crucial. We tested a field experiment to examine long-term remediation effects compound microorganisms (CM), strong anion exchange adsorbent (SAX), processed oyster shell (POS), composite humic acids (CHA) on Cd contamination paddy fields under rice-oilseed rape rotation system. In comparison control group (CK), application amendments significantly increased soil pH, cation...

The WRKY transcription factor plays a crucial role in plant stress adaptation. Our research has found that WRKY6 Solanum tuberosum (potatoes) is closely related to cadmium (Cd) tolerance. Therefore, investigating the mechanism of StWRKY6 resistance Cd toxicity great scientific importance for food safety. This further analyzed gene structure and functional regions nuclear potatoes, discovering contains W box, GB/box, ABRE, other elements can act as regulatory execute multiple regulations....
