“…Low P also reduces leaf photosynthesis but increased the accumulation of starch in plant tissues [ 21 ]. Similarly, low P increased soluble sugars, sucrose, and starch contents in beans [ 22 ], tomatoes [ 23 ], and cotton leaves [ 24 ]. Under low P, a significant increase in carbohydrate contents was observed in the Arabidopsis leaves [ 25 ], however, an increase in carbohydrate contents inhibits photosynthesis [ 26 ], C metabolism, and biomass accumulation [ 27 ].…”

Low phosphorus (P) is one of the limiting factors in sustainable cotton production. However, little is known about the performance of contrasting low P tolerant cotton genotypes that might be a possible option to grow in low P condition. In the current study, we characterized the response of two cotton genotypes, Jimian169 a strong low P tolerant, and DES926 a weak low P tolerant genotypes under low and normal P conditions. The results showed that low P greatly inhibited growth, dry matter production, photosynthesis, and enzymatic activities related to antioxidant system and carbohydrate metabolism and the inhibition was more in DES926 as compared to Jimian169. In contrast, low P improved root morphology, carbohydrate accumulation, and P metabolism, especially in Jimian169, whereas the opposite responses were observed for DES926. The strong low P tolerance in Jimian169 is linked with a better root system and enhanced P and carbohydrate metabolism, suggesting that Jimian169 is a model genotype for cotton breeding. Results thus indicate that the Jimian169, compared with DES926, tolerates low P by enhancing carbohydrate metabolism and by inducing the activity of several enzymes related to P metabolism. This apparently causes rapid P turnover and enables the Jimian169 to use P more efficiently. Moreover, the transcript level of the key genes could provide useful information to study the molecular mechanism of low P tolerance in cotton.

“…All the DEPs were upregulated in L13_P0, implying that these proteins positively influence soybean response to P-free conditions. These DEPs were enriched in various KEGG pathways with the most enriched being 2-oxocarboxylic acid metabolism, carbon metabolism, biosynthesis of amino acids, glycolysis, oxidative phosphorylation, pentose phosphatase, other types of O -glycan biosynthesis and riboflavin metabolism in the metabolic pathways ( Morcuende et al 2007 ; Huang et al 2008 ; Warren et al 2011 ; Schlüter et al 2013 ; Müller et al 2015 ; Pant et al 2015 ; Deng et al 2018 ; Kc et al 2018 ; Liu et al 2020 ), likely to be crucial for tolerating P starvation in the soil ( Fig. 2A ).…”

Proteome characterization of two contrasting soybean genotypes in response to different phosphorus treatments

Phosphorus (P) is an essential element for the growth and development of plants. Soybean (Glycine max) is an important food crop that is grown worldwide. Soybean yield is significantly affected by P deficiency in the soil. To investigate the molecular factors that determine the response and tolerance at low-P in soybean, we conducted a comparative proteomics study of a genotype with low-P tolerance (Liaodou 13, L13) and a genotype with low-P sensitivity (Tiefeng 3 , T3) in a paper culture experiment with three P treatments i.e., P-free (0 mmol·L -1), low-P (0.05 mmol·L -1), and normal-P (0.5 mmol·L -1). A total of 4,126 proteins were identified in roots of the two genotypes. Increased numbers of differentially expressed proteins (DEPs) were obtained from low-P to P-free conditions compared to the normal P treatment. All DEPs obtained in L13 (660) were up-regulated in response to P deficiency, while most DEPs detected in T3 (133) were down-regulated under P deficiency. Important metabolic pathways such as oxidative phosphorylation, glutathione metabolism and carbon metabolism were suppressed in T3, which could have affected the survival of the plants in P-limited soil. In contrast, L13 increased the metabolic activity in the 2-oxocarboxylic acid metabolism, carbon metabolism, glycolysis, biosynthesis of amino acids, pentose phosphatase, oxidative phosphorylation, other types of O-glycan biosynthesis and riboflavin metabolic pathways in order to maintain normal plant growth under P deficiency. Three key proteins (I1KW20 (prohibitins), I1K3U8 (alpha amylase inhibitors), and C6SZ93 (alpha amylase inhibitors) were suggested as potential biomarkers for screening soybean genotypes with low P tolerance. Overall, this study provides new insights into the response and tolerance to P deficiency in soybean.

“…SPS activity was measured using the UDP-Glucose method and SuSy activity in the direction of sucrose decomposition was determined using the UDP method, as previous studies described [ 45 , 46 ]. The activities of AI and AKI were analyzed using the 3,5-dinitro salicylic acid (DNS) method, by sucrose (1 M) in acetic acid–NaOH (200 mM, pH 5.0) for AI or sodium acetate–acetic acid (100 mM, pH 7.5) for AKI.…”

A field experiment was established to study sweet potato growth, starch dynamic accumulation, key enzymes and gene transcription in the sucrose-to-starch conversion and their relationships under six K2O rates using Ningzishu 1 (sensitive to low-K) and Xushu 32 (tolerant to low-K). The results indicated that K application significantly improved the biomass accumulation of plant and storage root, although treatments at high levels of K, i.e., 300–375 kg K2O ha−1, significantly decreased plant biomass and storage root yield. Compared with the no-K treatment, K application enhanced the biomass accumulation of plant and storage root by 3–47% and 13–45%, respectively, through promoting the biomass accumulation rate. Additionally, K application also enhanced the photosynthetic capacity of sweet potato. In this study, low stomatal conductance and net photosynthetic rate (Pn) accompanied with decreased intercellular CO2 concentration were observed in the no-K treatment at 35 DAT, indicating that Pn was reduced mainly due to stomatal limitation; at 55 DAT, reduced Pn in the no-K treatment was caused by non-stomatal factors. Compared with the no-K treatment, the content of sucrose, amylose and amylopectin decreased by 9–34%, 9–23% and 6–19%, respectively, but starch accumulation increased by 11–21% under K supply. The activities of sucrose synthetase (SuSy), adenosine-diphosphate-glucose pyrophosphorylase (AGPase), starch synthase (SSS) and the transcription of Susy, AGP, SSS34 and SSS67 were enhanced by K application and had positive relationships with starch accumulation. Therefore, K application promoted starch accumulation and storage root yield through regulating the activities and genes transcription of SuSy, AGPase and SSS in the sucrose-to-starch conversion.
