Summary Drought resistance (DR) is a complex trait that regulated by variety of genes. Without comprehensive profiling DR‐related traits, the knowledge genetic architecture for DR in cotton remains limited. Thus, there need to bridge gap between genomics and phenomics. In this study, an automatic phenotyping platform (APP) was systematically applied examine 119 image‐based digital traits (i‐traits) during drought stress at seedling stage, across natural population 200 representative upland...

Summary N 6 ‐methyladenosine (m A) is the most prevalent internal modification present in mRNAs, and considered to participate a range of developmental biological processes. Drought response highly regulated at genomic, transcriptional post‐transcriptional levels. However, function regulatory mechanism m A drought stress still poorly understood. We generated transcriptome‐wide map using drought‐resistant drought‐sensitive varieties cotton under different water deficient conditions uncover...

Abstract The occurrence of whole-genome duplication or polyploidy may promote plant adaptability to harsh environments. Here, we clarify the evolutionary relationship eight GhCIPK6 homologous genes in upland cotton ( Gossypium hirsutum ). Gene expression and interaction analyses indicate that show significant functional changes after polyploidy. Among these, GhCIPK6D1 GhCIPK6D3 are significantly up-regulated by drought stress. Functional studies reveal high promotes sensitivity, while...

Calcineurin B-like protein (CBL) and CBL-interacting kinase (CIPK)-mediated calcium signaling has been widely reported to function in plant development various stress responses, particularly ion homeostasis. Sugars are the most important primary metabolites, thus sugar homeostasis requires precise regulation. Here, we describe a CBL2-CIPK6-Tonoplast-Localized Sugar Transporter2 (TST2) molecular module cotton (Gossypium hirsutum) that regulates homeostasis, particular Glc GhCIPK6 is recruited...

Abscission is a process that allows plants to shed tissues or organs via cell separation, and occurs throughout the life cycle. Removal of leaves through use chemical defoliants very important for mechanical harvesting cotton (Gossypium hirsutum). However, our knowledge molecular mechanisms defoliation response involved limited. In this study, RNA-seq was conducted in order profile differentially expressed genes (DEGs) between cultivars X50 (sensitive defoliants) X33 (relatively insensitive)...

Abstract Wounded plant cells can form callus to seal the wound site. Alternatively, wounding cause adventitious organogenesis or somatic embryogenesis. These distinct developmental pathways require specific cell fate decisions. Here, we identify GhTCE1, a basic helix–loop–helix family transcription factor, and its interacting partners as central regulatory module of early transition during in vitro dedifferentiation cotton (Gossypium hirsutum). RNAi- CRISPR/Cas9-mediated loss GhTCE1 function...

Drought is the principal abiotic stress that severely impacts cotton (Gossypium hirsutum) growth and productivity. Upon sensing drought, plants activate stress-related signal transduction pathways, including ABA mitogen-activated protein kinase (MAPK) cascade. However, as key components with fewest members in MAPK cascade, function regulation of GhMKKs need to be elucidated. In addition, relationship between module core signaling pathway remains incompletely understood.Here we aim elucidate...

Abstract: The depletion of soil nutrients and the increased erodibility have exacerbated degree degradation, thereby impeding sustainable development ecosystems. Vegetation restoration, as a widely implemented measure to prevent is valued for its role in enhancing reducing erodibility. To investigate impact vegetation restoration measures on Loess Hilly Region, this study selected Wuqi County, pioneer county China's Grain-for-Green Project, research site, with sloping farmland serving...

Abstract: Understanding the spatiotemporal changes of sediment yield in watersheds over long time scales and their influencing factors is great significance for soil water conservation. Taking upper Beiluo River Basin(7325 km2)as an example, WaTEM/SEDEM model was used to analyze characteristics erosion watershed from 1980 2016, as well driving factors, providing a scientific theoretical basis conservation on Loess Plateau. The results show that there have been significant land use Basin....

Abstract: Clarifying the complex dynamics of ecosystem service (ES) flows and identifying key locations supply-demand chain is crucial for achieving sustainable management services.

Abstract:Revegetation is vital for enhancing soil carbon sequestration. However, the impacts of revegetation and terracing measures on organic (SOC) and SOC sequestration (SOCS), and the differences in effects revegetation on SOCS when implemented sloped fields versus terraced fields, are still unclear. Thus, we conducted a field survey cropland (CL), grassland (GL), forestland (FL) both Wuqi county, China’s Loess Plateau. The results...
