“…They further found that different plants responded differently to the same isolate. In relation to photosynthesis, phosphorus play an important role in energy transfer (Carstensen et al, 2018;Meng et al, 2021). Unfortunately, under P deficiency, P is allocated more to roots than to leaves (Muhammad, Abdullah, Saud, Shaharuddin, & Isa, 2021).…”

Each plant genotype has its own photosynthetic parameters required to run crop growth model. The research is aimed to characterize photosynthetic parameters particularly maximum photosynthesis and initial light use efficiency of two soybean varieties widely planted in Indonesia, Dena-1 and Anjasmoro. Photosynthetic performances were measured in a designed experiment to study the effect of Actinomycetes spp. on growth and yield of soybean. Photosynthesis was measured using an open chamber portable photosynthetic system (LI-6400), at variable Photosynthetically Active Radiation (PAR), i.e. 500; 1,000; 1,500; and 2,000 µmol (photon)/m 2 /s. The photosynthetic light response curve (PN/I curve) was developed using Solver function of Microsoft Excel. Maximum gross photosynthesis (P gmax ) of Dena-1 is 45.64 μmol (CO 2 )/m 2 /s, while Anjasmoro variety is only 34.81 μmol (CO 2 )/m 2 /s. Quantum yield at low light (initial light use efficiency) of Dena-1 is also higher with the value of 0.068 μmol (CO 2 )/μmol(photons) compared to Anjasmoro that have 0.058 μmol (CO 2 )/μmol (photons). Hence light response curve of Dena-1 variety is consistently higher than Anjasmoro. Under Actinomycetes spp. treatment the light response curve of Dena-1 is higher than Anjasmoro at PAR lower than 706 μmol (photon)/m 2 /s and higher at PAR above it.

Biomass and mineral nutrient partitioning among self-pollinated and cross-pollinated fruit on the same strawberry plant

et al. 2022

Pollen-parent effects on fruit size and quality have been found previously among competing self-pollinated and cross-pollinated fruit on the same Redlands Joy strawberry plant. These effects occur independently of the percentage of fertilized seeds on the fruit, but the expression of these effects on fruit size and some aspects of quality are greatest when calcium is in shortest supply. Here, we aimed to clarify at what developmental stages the self-pollinated and cross-pollinated fruit diverge in size and quality and whether differences between self-pollinated and cross-pollinated fruit are due to early differences in nutrient accumulation. Fruit were harvested at 1, 2 and 3 weeks after hand-pollination and at full ripeness, approximately 4 weeks after hand-pollination. We measured fruit mass, length, diameter, colour, and the concentrations of aluminium, boron, calcium, copper, iron, nitrogen, magnesium, manganese, sodium, phospho-rous, potassium and zinc. Temporary increases in fruit mass, length or diameter due to cross-pollination were evident at 1 or 2 weeks after pollination. Consistent increases in size and skin darkness from cross-pollination emerged in the final week of fruit development. We found little evidence that self-pollinated and cross-pollinated fruit differed in mineral nutrient accumulation at any stage of fruit development. The results demonstrate that cross-pollination effects on strawberry fruit size are evident briefly during early fruit growth but emerge mainly during the final week of fruit development. The effects of cross-pollination on fruit size are not the result of early differences in mineral nutrient accumulation between self-pollinated and cross-pollinated fruit.

“…N de ciency decreased the content of P and up-regulated the expression levels of genes sencoding inorganic P transporter 1-5, PHO1, and some genes involved in cellular response to phosphate starvation in rice [14,56]. Conversely, P de ciency could also decrease the content of N in citrus leaves [57]. In the current study, we found that except for inorganic phosphate transporter 1-4 (TEA010724.1), the expression levels of four phosphate transporter genes, named probable anion transporter 3 (chloroplastic TEA015946.1, TEA004543.1), probable inorganic phosphate transporter 1-9 (TEA003831.1), and K14684 solute carrier family 25 (mitochondrial phosphate transporter) (TEA020321.1), were up-regulated by N de ciency in tea leaves (Additional le 6).…”

Background: As an economically important crop, tea is strongly nitrogen-dependent. However, the physiological and molecular mechanisms underlying the response of N deficiency in tea are not fully understood. Tea cultivar “Chunlv” [Camellia sinensis (L.) O. Kuntze] were cultured with nutrient solution with 0 mM (N-deficiency) or 3 (control) mM NH4NO3 in 6 L pottery pots containing clean river sands. Results: N deficiency significantly decreased N content and biomass,Chl content, NR, NiR and GOGAT activity, but increased the content of total flavonoids in tea leaves. N deficiency delayed the sprouting time of tea buds. By using RNA-seq technique and subsequent bioinformatics analysis, 3050 up-regulated and 2688 down-regulated DEGs were isolated in tea leaf in response to N deficiency. However, only 1025 genes were up-regulated and 744 down-regulated in roots. GO term enrichment analysis showed that 205 DEGs in tea leaves were enriched in seven GO terms and 152 DEGs in tea roots were enriched in 11 GO items based on P < 0.05. In tea leaves, most of GO-enriched DEGs were involved in chlorophyll a/b binding activities, photosynthetic performance and transport activities in tea leaves. But most of DEGs in tea roots were involved in the metabolism of carbohydrate and plant hormone with regard to the GO terms of biological processes. It is worth mentioning that N deficiency significantly increased the expression level of phosphate transporter genes, which indicated that N deficiency might impair phosphorus metabolism in tea leaves. Furthermore, some DEGs, such as NATs, probable anion transporter 3 and high affinity nitrate transporter 2.7, might be of great potential on improving the tolerance of N deficiency in tea plants and further study could work on this area in the future. Conclusions: These results increased our knowledge about physiological and molecular mechanisms of tea plant in response to N limited condition.
