Microbial populations have diverse roles within rhizosphere where interactions among distinct microorganisms along with the host may lead to mutualistic associations. The present study aimed to investigate the nutritional and antioxidant qualities of seeds and pericarp of pea raised from seeds treated with beneficial microbes namely Bacillus subtilis BHHU100, Trichoderma harzianum TNHU27 and Pseudomonas aeruginosa PJHU15 either singly and/or in consortia. A significant increase in total phenolic, flavonoid, ascorbic acid and protein contents, free radical scavenging activity, hydroxyl radical scavenging activity, iron chelation and reducing power were observed in the seeds and pericarp of pods treated with a consortium of microbes in comparison to control pods. Also, the differential accumulation of phenolic compounds, namely, shikimic acid, gallic acid, tannic acid, syringic acid, p-coumaric acid, quercetin and kaempferol, was observed from the HPLC chromatogram of the seed extracts of different treatments. We especially emphasized on dietary importance of the pod pericarp, other than seeds, along with their modulation by microbial consortium. The study also highlights the role of beneficial microbes in improving nutritional value by providing protection against oxidative stress.

Signaling pathways mediating the induction of preharvest fruit drop in litchi.
Front Plant Sci

State Key Laboratory for Conservation and Utilization of Subtropical Agro-Bioresources, College of Horticulture, South China Agricultural University, Guangzhou, China.
Certain litchi varieties, such as "Nuomici", are highly susceptible to preharvest fruit drop, which leads to significant losses in fruit yield and economic value. However, the precise molecular mechanisms underlying this issue are not yet fully understood. In this study, we aimed to elucidate the signaling pathways that facilitate preharvest fruit drop in litchi, using "Nuomici" and "Huaizhi" cultivars as examples, which demonstrate high and low preharvest fruit drop rates, respectively.

In barley having adherent hulls, an irreversible connection between the pericarp with both palea and lemma is formed during grain maturation. A mutation in the () gene prevents this connection and leads to the formation of barley with non-adherent hulls. A genetic model of two isogenic lines was used to elucidate the genetic mechanisms of hull adhesion: a doubled haploid line having adherent hulls and its derivative with non-adherent hulls obtained by targeted mutagenesis of the gene.

(Lour.) Skeels, commonly known as Wampee, are valued for their edible and medicinal qualities, yet their pericarp and seeds are often discarded, resulting in wasted resources. This study investigates the anti-tumor potential of these by-products, focusing on their chemical composition and underlying mechanisms of action.

Article Synopsis
- The dry dehulling process for quinoa faces issues like poor clarity and inefficiency, resulting in product loss, which can be improved through accurate simulations.
- Using EDEM simulation software, researchers developed a discrete-element model that effectively simulates quinoa grain characteristics and calibrates bonding parameters through various testing methods.
- The simulation results showed high accuracy, with minimal errors compared to real measurements, and achieved better dehulling efficiency, providing a reliable approach for enhancing dry dehulling equipment design.
Seed quality and relative lignan profiles of sesame prospected from northern Ghana.

The sesame seed contains oil, protein, dietary fibre, and several minerals and it is also a store of lignans. Lignans are key selection factors for sesame quality due to their health, nutritive and market value. In Ghana sesame growers rely on wild or undocumented planting seeds which are of mixed colouration and its lignan content is ambiguous.
