The fundamental key to increase photosynthetic efficiency of crop plants lies in optimizing the light energy use efficiency. In our study, we used tomato evaluate allocation absorbed young and mature leaves, estimate if extent photoinhibition photoprotection can be affected by leaf age. A reduced oxygen-evolving complex, leaves compared ones, resulted a donor-side photoinhibition, as judged from significantly lower Fv/Fm ratio, leaves. detected increased 1O2 production was probably due photoinhibition. effective quantum yield photosystem II (PSII) photochemistry (ΦPSII), at low intensity (LLI, 426 μmol photons m−2 s−1), Moreover, non-significant non-photochemical loss PSII (ΦNPQ) could not counteract decreased ΦPSII, result non-regulated (ΦNO) ones. ΦPSII attributed reactive oxygen species (ROS) creation that diminished open reaction centers (Fv’/Fm’), but without having any impact on fraction centers. excess excitation energy, LLI, also revealed an enhanced However, there almost no difference between high (HLI, 1000 s−1). ability constrain is possible related function better growth rate. We concluded influenced both age intensity. Furthermore, degrees are developmental stage.

SUMMARY Improving the efficiency of crop photosynthesis has potential to increase yields. Genetic manipulation showed can be improved by speeding up relaxation photoprotective mechanisms during sun‐to‐shade transitions. However, it is unclear if natural variation in non‐photochemical quenching (NPQ) exploited breeding programs. To address this issue, we measured six NPQ parameters 40 founder lines and common parent a Soybean Nested Association Mapping (SoyNAM) panel over two field seasons Illinois. Leaf disks were sampled from plants grown field, induction under controlled conditions. did not show consistently variable trends throughout development, between sampling days suggests environmental impacts on dynamics. Seventeen genotypes found small but consistent differences kinetics relative reference line, providing basis for future mapping studies. Finally, soybean canopy model predicted available phenotypic could result 1.6% difference carbon assimilation when comparing fastest slowest relaxing values. No correlation yield rates relaxation, full test will require an analysis isogenic lines.

Various metal-based nanomaterials have been the focus of research regarding their use in controlling pests and diseases improving crop yield quality. In this study, we synthesized via a solvothermal procedure pegylated zinc-doped ferrite (ZnFer) NPs characterized physicochemical properties by X-ray diffraction (XRD), vibrating sample magnetometry (VSM), thermogravimetric analysis (TGA), FT-IR UV-Vis spectroscopies, as well transmission electron microscopy (TEM). Subsequently, impact on tomato photosynthetic efficiency was evaluated using chlorophyll fluorescence imaging to estimate light energy photosystem II (PSII), 30, 60, 180 min after foliar spray plants with distilled water (control plants) or 15 mg L-1 30 ZnFer NPs. The PSII responses leaves showed time- dose-dependent biphasic hormetic responses, short-time inhibitory effect low dose stimulatory high dose, while at longer exposure period, reverse phenomenon recorded doses. An function observed more than ~120 both concentrations, implying negative photochemistry. We may conclude that NPs, despite ability induce hormesis photochemistry, function.

Wheat is an important cereal crop used to produce diverse and popular food worldwide because of its high grain yield (GY) protein content (GPC). However, GY GPC are usually negatively correlated. We previously reported that favorable alleles the wheat domestication gene Q can synchronously increase GPC, but underlying mechanisms remain largely unknown. In this study, we investigated regulatory network involving associated with in young grains through DNA affinity purification sequencing transcriptome analyses, electrophoretic mobility shift dual-luciferase assays, transgenic approaches. Three Q-binding motifs, namely TTAAGG, AAACA[A/T]A, GTAC[T/G]A, were identified. Notably, genes related photosynthesis or carbon nitrogen metabolism enriched regulated by Q. Moreover, was revealed bind directly own glutamine synthetase TaGSr-4D expression, thereby influencing assimilation during filling stage increasing GPC.

Abstract High‐throughput digital phenotyping (DP) has been widely explored in plant breeding to assess large numbers of genotypes with minimal manual labor and reduced cost time. DP platforms using high‐resolution images captured by drones tractor‐based have recently allowed the University Florida strawberry ( Fragaria × ananassa ) program vegetative biomass at scale. Biomass not previously a context due required need destroy plant. This study aims understand genetic basis predicted biomass‐related traits chart path for combined use genomics breeding. Aboveground dry was estimated adapting published model ground‐truth data on subset germplasm. High‐resolution were collected clonally replicated trials different time points during fruiting season. There moderate high heritability h 2 = 0.26–0.56) biomass, correlations between marketable yield mostly positive r G −0.13–0.47). Fruit scaled also had 0.25–0.64). suggests that can be decreased or increased through selection, fruit improved without simultaneously increasing size. No consistent marker‐trait associations discovered via genome‐wide association studies. On other hand, predictive abilities from genomic selection ranged 0.15 0.46 across years, suggesting prediction will an effective tool strawberry.
