Aluminum alloy plates are widely used to manufacture large-scale integral structure parts in the field of aerospace. During the forming and processing of aluminum alloy plates, different degrees of residual stress are inevitably produced. Fast and accurate detection of residual stress is very essential to ensuring the quality of these plates.

Modern tomatoes produce colorful mature fruits, but many wild tomato ancestors form green or gray green ripe fruits. Here, tomato cultivar 'Lvbaoshi' (LBS) that produces green ripe fruits was found to contain three recessive loci responsible for fruit development. The colorless peel of LBS fruits was caused by a 603 bp deletion in the promoter of SlMYB12.

Trichomes that originate from plant aerial epidermis act as mechanical and chemical barriers against herbivores. Although several regulators have recently been identified, the regulatory pathway underlying multicellular trichome formation remains largely unknown in tomato. Here, we report a novel HD-ZIP IV transcription factor, Lanata (Ln), a missense mutation which caused the hairy phenotype.

Background: CONSTANS (CO) and CONSTANS-LIKE (COL) transcription factors have been known to regulate a series of cellular processes including the transition from the vegetative growth to flower development in plants. However, their role in regulating fruit yield in tomato is poorly understood.

Result: In this study, the tomato ortholog of Arabidopsis CONSTANS, SlCOL1, was shown to play key roles in the control of flower development and fruit yield.

Reactive oxygen species (ROS) are inevitably generated in aerobic organisms as by-products of common metabolism and as the result of defense and development. ROS readily oxidizes methionine (Met) residues of proteins to form Met-R-sulfoxide or Met-S-sulfoxide (MetSO), resulting in protein inactivation or malfunction. Although it is known that MetSO can be reverted to Met by methionine sulfoxide reductase (Msr), the mechanism how Msr interacts with its target proteins is poorly understood.

Shore-based water wave energy produced by the impact of ocean waves on the coastline is a kind of clean and renewable energy. In this paper, a pendular-translational hybrid nanogenerator (PT-HNG) with two multilayer triboelectric nanogenerators and a spring base is proposed to harvest the wave energy. Pendular-translational movement mechanism is a sliding rail structure embedded with a permanent magnet, and the output is greatly improved compared to the previous pendular-pendular movement mechanism.

Article Synopsis
  • Trichomes are structures on plants that help protect against pests and diseases, with non-glandular types studied in Arabidopsis, while the formation of glandular trichomes is less understood.
  • Research found that a protein called Hair is crucial for the formation and growth of both type I and type VI trichomes, and when overexpressed, it increases the density and size of trichomes in tomatoes.
  • The study identified that Hair interacts with a related protein SlZFP8-like, which also boosts trichome growth, and Hair regulates the expression of another protein, SlZFP6, showing a complex interaction that controls trichome initiation and elongation in tomato plants.

NF-Y transcription factors are reported to play diverse roles in a wide range of biological processes in plants. However, only a few active NF-Y complexes are known in plants and the precise functions of NF-Y complexes in flavonoid biosynthesis have not been determined. Using various molecular, genetic and biochemical approaches, we found that NF-YB8a, NF-YB8b and NF-YB8c - a NF-YB subgroup - can interact with a specific subgroup of NF-YC and then recruit either of two distinct NF-YAs to form NF-Y complexes that bind the CCAAT element in the CHS1 promoter.

C2H2 zinc finger proteins (ZFPs) play essential roles in leaf morphogenesis and floral development, as well as heat stress response and trichome formation, which activate or inhibit gene transcription mainly through interactions with nucleic acids, such as single-strand DNA, RNA binding or RNA/DNA bidirectional binding, and protein interaction. Single C2H2 ZFPs is the subfamily of ZFPs, but little of single C2H2 ZFP family is known in tomato. In this study, we identified 30 single ZFP genes in tomato using bioinformatics-based methods.

Article Synopsis
  • - The study investigates the type-B authentic response regulators (ARR-Bs) in tomato, identifying 12 genes (SlARR-B1 to SlARR-B12) that help regulate cytokinin signaling and influence stress resistance and plant development.
  • - Analysis revealed the SlARR-B genes have varying structures and are spread across eight chromosomes, classified into six subfamilies based on their evolutionary relationships.
  • - Expression profiling showed these genes are active in different tomato tissues, particularly in flowers for SlARR-B11 and SlARR-B12, and respond to various phytohormones and abiotic stressors like heat and drought.

The inflorescences and lateral branches of higher plants are generated by lateral meristems. The structure of the inflorescence has a direct effect on fruit yield in tomato (Solanum lycopersicum). We previously demonstrated that miR156a plays important roles in determining the structures of the inflorescences and lateral branches in tomato by suppressing the expression of the SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) transcription factor gene family.

Trichomes originate from the epidermal cells of nearly all terrestrial plants, which are specialized unicellular or multicellular structures. Although the molecular mechanism regulating unicellular trichome formation has been extensively characterized, most of the genes essential for multicellular trichome formation remain unknown. In this study, we identified an associated locus on the long arm of chromosome 10 using a genome-wide association study (GWAS) on type-I trichomes of 180 diverse Solanum lycopersicum (tomato) accessions.
