Title

Continuous Cropping Inhibits Photosynthesis of Polygonatum odoratum

Yan Wang; Yunyun Zhou; Jing Ye; et al. Plants 2023. doi:10.3390/plants12193374

Other claims from this paper (4)

Intervention effect Continuous cropping changed chlorophyll content, light response curves and photosynthetic parameters.
Observation Continuous cropping leaves had 13,798 differentially expressed genes relative to first cropping.
Observation Among these genes, 7932 unigenes were upregulated.
Observation Among these genes, 5860 unigenes were downregulated.

Other claims from this paper (9)

Intervention effect Sigesbeckia root extracts reduced Ambrosia height and biomass.
Mechanism Biomass decline may reflect disrupted carbon and nitrogen metabolism.
Intervention effect Extract exposure significantly decreased root nitrate absorption and transport gene expression.
Observation Genes involved in sucrose synthesis were downregulated.
Observation H 2 O 2 content and RbohD expression increased.
Observation Apoptotic pathway genes were significantly upregulated.
Observation Coumarin, ferulic acid and 5-ALA were identified in Sigesbeckia extracts.
Intervention effect The three allelochemicals together suppressed Ambrosia seedling growth.
Observation Chemical-treated seedlings had the same phenotypes and transcriptomes as extract-treated seedlings.

Title

Effect of Acclimation to High Temperatures on the Mechanisms of Drought Tolerance in Species with Different Types of Photosynthesis: Sedobassia sedoides (C3–C4) and Bassia prostrata (C4-NADP)

E. V. Shuyskaya; Z. F. Rakhmankulova; M. Yu. Prokofieva; et al. Физиология растений 2023. doi:10.31857/s0015330323600195

Other claims from this paper (13)

Intervention effect Drought decreased biomass, water content and effective quantum yield of PSII in Sedobassia sedoides regardless of growing temperature.
Intervention effect Drought decreased biomass, water content and effective quantum yield of PSII in Bassia prostrata regardless of growing temperature.
Intervention effect Drought increased psbA gene expression in Sedobassia sedoides.
Intervention effect Drought increased psbA gene expression in Bassia prostrata.
Intervention effect Drought decreased the content of photosynthetic enzymes in Sedobassia sedoides.
Intervention effect Drought decreased the content of photosynthetic enzymes in Bassia prostrata.
Intervention effect Acclimation of Sedobassia sedoides to elevated temperatures increased the activity of cyclic electron transport around PSI.
Intervention effect Acclimation of Sedobassia sedoides to elevated temperatures reduced the drought-induced NPQ, mitigating the drought effect on light reactions.
Intervention effect Acclimation of Sedobassia sedoides to elevated temperatures changed the content of the PEPC enzyme under drought.
Intervention effect Acclimation of Sedobassia sedoides to elevated temperatures decreased potassium content and shifted the ionic balance.
Observation Bassia prostrata showed greater drought resistance than the other species.
Observation Bassia prostrata had greater thermolability of photosynthetic enzymes.
Mechanism Changes in the content and ratio of photosynthetic enzymes allowed Bassia prostrata to maintain growth under drought at different temperatures.
