“…The GLABRA 1 (GL1)-GLABRA 3 (GL3)/ENHANCER OF GLABRA 3 (EGL3)-TRANSPARENT TESTA GLABRA 1 (TTG1) trichome development complex has been well studied ( Zhao et al, 2008 ); however, knowledge of the interaction between this complex and phytohormones is limited. Sweet wormwood ( Artemisia annua ), tomato ( Solanum lycopersicum ), and cucumber ( Cucumis sativus ) are the main plant species used as models for studying glandular trichome development ( Lv et al, 2017 ; Du et al, 2020 ; Xiong et al, 2020 ), and many studies have indicated that trichome development involves phytohormones ( Yan et al, 2017 ; Chen et al, 2020 ; Yuan et al, 2021 ).…”

Phytohormones affect plant growth and development. Many phytohormones are involved in the initiation of trichome development, which can help prevent damage from UV radiation and insect bites and produce fragrance, flavors, and compounds used as pharmaceuticals. Phytohormones promote the participation of transcription factors in the initiation of trichome development; for example, the transcription factors HDZIP, bHLH and MYB interact and form transcriptional complexes to regulate trichome development. Jasmonic acid (JA) mediates the progression of the endoreduplication cycle to increase the number of multicellular trichomes or trichome size. Moreover, there is crosstalk between phytohormones, and some phytohormones interact with each other to affect trichome development. Several new techniques, such as the CRISPR-Cas9 system and single-cell transcriptomics, are available for investigating gene function, determining the trajectory of individual trichome cells and elucidating the regulatory network underlying trichome cell lineages. This review discusses recent advances in the modulation of trichome development by phytohormones, emphasizes the differences and similarities between phytohormones initially present in trichomes and provides suggestions for future research.

“…The microscopic or ultrastructure of plant leaves, particularly the relationship between trichome types and their response to adversity stress, the relationship between microscopic morphological characteristics and the internal structure of leaves, and the relationship between varieties and diseases have rarely been investigated.To assess the relation between the type or density of trichomes and stress resistance, differences in the type, structure, glandular status, and gross density of the trichomes among two wo mutant LA3186 varieties (a hairy cultivar and a hairless cultivar), the natural ln mutant LA3-071, and a common tomato cultivar were compared. The Wo (Wolly) gene can promote the formation of multicellular trichome involved in modulating wax biosynthesis in tomato [18]. 3186M and 3186L are two mutants of wo, showing hairy and hairless traits, respectively.…”

The Roles of Different Types of Trichomes in Tomato Resistance to Cold, Drought, Whiteflies, and Botrytis

The tomato (Solanum lycopersicum) is one of the most popular vegetables in the world. In tomato production, due to the effects of diseases, insect pests, drought, and cold damage, large-scale production reduction is often caused. Plant trichomes are protruding attachments distributed on the surface of different plants, providing protection for plants. When the plant is under external stress, the trichomes can play an important role in protecting the plant from damage through its physical structure. The density and type of different trichomes are closely related to the stress resistance of tomatoes. The tomato wo mutant LA3186 (referred to herein as "3186M"), LA3186 (referred to herein as "3186L"), the ln mutant LA3-071 (referred to herein as "3-071"), and the tomato cultivar Jia Ren (referred to herein as "JR", used as the control), which possess different numbers of trichomes on the surface of the leaves, were used as materials; the glandular characteristics, types, and densities of the trichomes were observed under a scanning electron microscope (SEM); and transmission electron microscopy (TEM) was used to observe the subcellular structure in the leaves. The relationship between the different tomato trichomes and stress resistance was investigated with treatments of low temperature, drought, disease, and insects. This study provides a theoretical foundation and practical basis for the further utilization and regulation of the trichome-related characteristics of tomatoes.Agronomy 2020, 10, 411 2 of 16 VII are glandular trichomes, and II, III, V and VIII are nonglandular trichomes [8]. Type I glandular trichomes consist of six to 10 cells of slender glandular trichomes, are 2-3 mm in length, and have spherical and multicellular bases with small, round glandular cells at the hairy tip. Type I trichomes mainly contain acyl glucose. Type II nonglandular trichomes resemble type I trichomes but are nonglandular and short (0.2-1.0 mm) and have spherical and multicellular bases. Both type I glandular trichomes and type II nonglandular trichomes are spherical and multicellular at their base. The glands of the type I, IV, and VI trichomes contain acyl flavonoids, terpenoids, and sugars. Of these compounds, acyl sugar has a very high viscosity and can thus stick to herbivores and prevent them from feeding freely on the surface of a plant [9]. In addition, an increase in the flavonoid content on the surface of plants can prevent the exposure of the plant to highly penetrating UV-A (longwave blackspot-effect ultraviolet rays) and excessive damage [5]. Tomatoes can also produce or release some highly toxic compounds to prevent pest damage [2]. Dong and Huang found that trichomes of wheat cultivars resistant to root rot were significantly longer than those of commonly susceptible cultivars. This finding suggested that trichomes on plant leaves play an important role in resistance to wheat root rot pathogens [10,11].Trichomes can also protect plants from being damaged by excessive temperature and drought stress [12][13][14].

“…The effects on cuticle formation of natural genetic variants found in cultivated tomato were also explored. STICKY PEEL encodes a HD-Zip IV protein that regulates epidermis metabolism and additional cuticle-associated traits ( Kimbara et al, 2012 ; Nadakuduti et al, 2012 ) while WOOLY , a different HD-Zip IV protein, regulates trichome initiation and wax biosynthesis ( Xiong et al, 2020 ). GA2-OXIDASE , which was identified through a fruit firmness QTL analysis, is unexpectedly related to a cuticle thickness QTL ( Li et al, 2020 ) and connects cuticle formation with gibberellin (GA) signaling.…”

Unraveling Cuticle Formation, Structure, and Properties by Using Tomato Genetic Diversity

The tomato (Solanum lycopersicum) fruit has a thick, astomatous cuticle that has become a model for the study of cuticle formation, structure, and properties in plants. Tomato is also a major horticultural crop and a long-standing model for research in genetics, fruit development, and disease resistance. As a result, a wealth of genetic resources and genomic tools have been established, including collections of natural and artificially induced genetic diversity, introgression lines of genome fragments from wild relatives, high-quality genome sequences, phenotype and gene expression databases, and efficient methods for genetic transformation and editing of target genes. This mini-review reports the considerable progresses made in recent years in our understanding of cuticle by using and generating genetic diversity for cuticle-associated traits in tomato. These include the synthesis of the main cuticle components (cutin and waxes), their role in the structure and properties of the cuticle, their interaction with other cell wall polymers as well as the regulation of cuticle formation. It also addresses the opportunities offered by the untapped germplasm diversity available in tomato and the current strategies available to exploit them.
