Regulation of Rubisco Carboxylation Activity and Photosynthetic Rate by Rubisco Activase during Leaf Senescence in Rice

open access: yes浙江大学学报. 农业与生命科学版, 2000
Photosynthetic rate, contents of soluble protein, chlorophyll, Rubisco and Rubisco activase, activities of Rubisco initial carboxylation and Rubisco activase were traced to clarify whether Rubisco activase regulates Rubisco activity and photosynthetic ...

Analysis of the Factors Causing Differences in the Leaf-Senescence Pattern between Two Soybean Cultivars, Enrei and Tachinagaha: Comparison of root length and exudation rate among grafted plants [PDF]

open access: yesPlant Production Science, 2001
To clarify the factors causing the differences in the leaf-senescence pattern between the soybean cultivars, Tachinagaha (T, late senescing cv) and Enrei (E, early senescing cv) , we grafted the T scion onto a T or E rootstock (T/T, T/E) andE scion onto ...

Differences in Sugar Accumulation and Mobilization between Sequential and Non-Sequential Senescence Wheat Cultivars under Natural and Drought Conditions. [PDF]

open access: yesPLoS ONE, 2016
Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves.

Leaf Tissue Senescence [PDF]

open access: yesPlant Physiology, 1975
During winter, excised leaf tissue from Rumex obtusifolius degrades chlorophyll at twice the summer rate but the plant hormones, gibberellic acid and zeatin, inhibit the senescence rate by a constant percentage, regardless of season.

Intercropping and Nitrogen Fertilization Altered the Patterns of Leaf Senescence in Sorghum

open access: yesInternational Journal of Agronomy, 2021
Leaf senescence regulates grain yield. However, the modulation of leaf senescence in sorghum under legume-based intercrop systems and nitrogen (N) fertilization is not known.

Shade-Induced Leaf Senescence in Plants

open access: yesPlants, 2023
Leaf senescence is a vital developmental process that involves the orderly breakdown of macromolecules to transfer nutrients from mature leaves to emerging and reproductive organs. This process is essential for a plant’s overall fitness.

359 Irrigation Rate and Nitrogen Concentration Affect Plant Growth and Leaf Senescence of Citrus Rootstock Seedlings [PDF]

open access: yesHortScience, 2000
The interactive effects of irrigation rate and nitrogen concentration of the irrigation water on the growth of seedlings of two citrus rootstocks were studied. Four-month old seedlings of Swingle citrumelo [ Citrus paradisi Macf.

Analysis of Physiological and Transcriptomic Differences between a Premature Senescence Mutant (GSm) and Its Wild-Type in Common Wheat (Triticum aestivum L.)

open access: yesBiology, 2022
Premature leaf senescence has a profound influence on crop yield and quality. Here, a stable premature senescence mutant (GSm) was obtained from the common wheat (Triticum aestivum L.) cultivar Chang 6878 by mutagenesis with ethyl methanesulfonate.
