“…The availability of a reference genome, multiple large scale transcriptome datasets, genetic transformation techniques, and genetic diversity estimates for a large group of cultivars make G. hirsutum an attractive candidate for studying salt gland functions between salt adapted and sensitive cultivars (Shen et al, 2006; Khan et al, 2010; TianZi et al, 2010; Rodriguez-Uribe et al, 2011; Rahman et al, 2012; Xie et al, 2014; Li et al, 2015; Lin et al, 2015). However, the role of salt glands in adapting to salt stress in cotton has not been explored much until recent work published by Peng et al (2016).…”

Salt stress is a complex trait that poses a grand challenge in developing new crops better adapted to saline environments. Some plants, called recretohalophytes, that have naturally evolved to secrete excess salts through salt glands, offer an underexplored genetic resource for examining how plant development, anatomy, and physiology integrate to prevent excess salt from building up to toxic levels in plant tissue. In this review we examine the structure and evolution of salt glands, salt gland-specific gene expression, and the possibility that all salt glands have originated via evolutionary modifications of trichomes. Salt secretion via salt glands is found in more than 50 species in 14 angiosperm families distributed in caryophyllales, asterids, rosids, and grasses. The salt glands of these distantly related clades can be grouped into four structural classes. Although salt glands appear to have originated independently at least 12 times, they share convergently evolved features that facilitate salt compartmentalization and excretion. We review the structural diversity and evolution of salt glands, major transporters and proteins associated with salt transport and secretion in halophytes, salt gland relevant gene expression regulation, and the prospect for using new genomic and transcriptomic tools in combination with information from model organisms to better understand how salt glands contribute to salt tolerance. Finally, we consider the prospects for using this knowledge to engineer salt glands to increase salt tolerance in model species, and ultimately in crops.

“…It was established that WD40-coding gene AtTTG1 (TRANSPARENT TESTA GLABRA 1) in Arabidopsis is responsible for seed coat production, root hair development and control of anthocyanins biosynthesis (Oppenheimer et al, 1991;Galway et al, 1994;Liu, Osbourn, and Ma, 2015). Among four GhTTG1-GhTTG4 genes known to be involved in the cotton fibre growing initiation, GhTTG1 and GhTTG3 demonstrate close sequence similarity to the known AtTTG1 anthocyanin regulatory gene (Table 2) (Walker et al, 1999;Mehboob-ur-Rahman et al, 2012;B. Liu, Zhu, and Zhang, 2015).…”

Naturally coloured cotton is environmentally friendly, since bleaching and chemical dyeing are not needed during textile production. Studying moleculargenetic mechanisms underpinning pigment production may facilitate breeding cotton with coloured fibre. In the current review we summarize the known data on structural and regulatory genes involved in biosynthesis of flavonoid pigments proanthocyanidins (PAs) in brown and caffeic acid (CA) derivates in green fibre. The first chapter considers the first studies on fibre cotton inheritance, from the beginning of the last century. Then, we briefly review the biochemical and physico-chemical methods proving the presence of PAs in brown fibre and derivatives of CA in green cotton fibre. The biochemical analysis of coloured cotton fibre was followed by genetic studies of structural genes coding for enzymes participating in PAs and CA biosynthesis, transport and oxidation processes. We summarize the data on the genes coding for transcription factors from the MBW (MYB-bHLH-WD40) regulatory complex, which controls flavonoid biosynthesis in coloured cotton fibre. The regulatory gene most interesting as a target for markers-assisted breeding and genome editing is GhTT2-3A.

“…Duplicated accessions can be discarded to avoid redundancy. Selected genotypes/accessions reflecting the maximum phenotypic diversity can be explored using genomic tools including SSR-based characterization, genotyping by sequencing, and re-sequencing, together with the application of association mapping analysis including nested-association mapping (NAM) and genome-wide association study (GWAS) methods [20].…”
