Taxon: peanut ✕

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Claim · model-written summary

Peanut cultivar HY 39 had a larger decrease in pod dry weight than ZKH 1 under waterlogging.

Taxon: peanutArachis hypogaeae2
Material: HY 39e3
Outcome: PDWe3
Direction: decreasede3
Comparator: ZKH 1e3

Verbatim

e2
“Physiological and transcriptome data of two peanut cultivars [Zhongkaihua 1 (ZKH 1) and Huayu 39 (HY 39)] were studied under normal water supply and waterlogging stress for 5 or 10 days at the flowering stage”
✓ located verbatim in the source · abstract, characters 49–257

e3
“Compared with ZKH 1, the PDW of HY 39 decreased more probably because more photosynthate accumulated in the stem and leaves of HY 39 and could not be effectively transported to the pod”

Title

Other claims from this paper (14)

Intervention effect Waterlogging increased the main stem height, number of lateral branches and lateral branch length of peanut.
Intervention effect Waterlogging increased the stem diameter of peanut.
Intervention effect Waterlogging increased dry matter accumulation in peanut.
Association Dry matter accumulation under waterlogging was correlated with increases in SPAD and net photosynthetic rate (Pn) of peanut.
Intervention effect Waterlogging increased SPAD and net photosynthetic rate (Pn) in peanut.
Intervention effect Waterlogging upregulated genes related to porphyrin and chlorophyll metabolism and photosynthesis in peanut.
Mechanism The imbalance of the source-sink relationship under waterlogging was the main cause of peanut yield loss.
Intervention effect Waterlogging increased sucrose and soluble sugar contents in peanut.
Intervention effect Waterlogging decreased starch content in peanut.
Intervention effect Waterlogging decreased the activities of sucrose synthetase (SS) and sucrose phosphate synthetase (SPS) in peanut.
Mechanism The decreased sucrose synthetase and SPS activities under waterlogging may be due to changes in the expression of genes related to starch and sucrose metabolism.
Intervention effect Waterlogging caused photosynthate to accumulate in the stems and leaves of peanut.
Intervention effect Waterlogging decreased the ratio of pod dry weight to total dry weight (PDW/TDW) and yield of peanut.
Mechanism Peanut cultivar HY 39 accumulated more photosynthate in its stem and leaves, which probably prevented effective transport to the pod.
