e1“Drought stress is one of the potent abiotic stress limiting cassava ( Manihot esculenta ) yield globally”
e2“Xinxuan 048 (XX048) was exposed to well-watered control (CK, relative soil water content (RSWC) as 80 ± 5%), mild drought stress (LD, RSWC as 65 ± 5%), moderate drought stress (MD, RSWC as 50 ± 5%) and severe drought stress (SD, RSWC as 35 ± 5%) from 30 days after planting”
e3“Under drought stress conditions, cassava plant showed a substantial decline in plant height, stem diameter, leaf number, leaf water content, the ratio of free water content to bound water content of leaf (FW/BW), net photosynthetic rate ( Pn ), intercellular CO 2 concentration ( Ci ), stomatal conductance ( Gs ) and transpiration rate ( Tr ) compared with well watered plants”

- Intervention effect Under drought stress, leaf water content and the ratio of free to bound water content of leaf (FW/BW) declined compared with well-watered plants.
- Intervention effect Under drought stress, net photosynthetic rate, intercellular CO2 concentration and stomatal conductance declined compared with well-watered plants.
- Intervention effect Under drought stress, transpiration rate declined compared with well-watered plants.
- Intervention effect Under drought stress, leaf water content, SPAD value and cell membrane permeability were at peak compared with control.
- Intervention effect Under drought stress, malondialdehyde (MDA) and soluble sugar were at peak compared with control.
- Intervention effect Under drought stress, protein proline content, SOD and CAT activity were at peak compared with control.
- Intervention effect Drought stress increased the abundance of 262 proteins in cassava leaves compared with control.
- Intervention effect Drought stress decreased the abundance of 296 proteins in cassava leaves compared with control.
- Observation The drought-changed proteins were involved in carbohydrate energy metabolism, protein homeostasis and transcription.
- Observation The drought-changed proteins were involved in cell structure, cell membrane transport and signal transduction.
- Observation The drought-changed proteins were involved in stress and defense responses.
- Mechanism The authors suggest the proteomic changes reveal how Euphorbiaceae plants such as cassava adapt to drought.
