“…Abnormal development in the floral bud formation in witches’-Broom Disease of soybean causes, even acute loss in productivity [12]. It is referred in India as ‘floral bud distortion’ caused by phytoplasma [14, 15]. In USA and Iran, it is called bud proliferation syndrome [16], and pod set failure [17, 18], respectively.…”

BackgroundSoybean (Glycine max L. Merril) crop is major source of edible oil and protein for human and animals besides its various industrial uses including biofuels. Phytoplasma induced floral bud distortion syndrome (FBD), also known as witches’ broom syndrome (WBS) has been one of the major biotic stresses adversely affecting its productivity. Transcriptomic approach can be used for knowledge discovery of this disease manifestation by morpho-physiological key pathways.ResultsWe report transcriptomic study using Illumina HiSeq NGS data of FBD in soybean, revealing 17,454 differentially expressed genes, 5561 transcription factors, 139 pathways and 176,029 genic region putative markers single sequence repeats, single nucleotide polymorphism and Insertion Deletion. Roles of PmbA, Zn-dependent protease, SAP family and auxin responsive system are described revealing mechanism of flower bud distortion having abnormalities in pollen, stigma development. Validation of 10 randomly selected genes was done by qPCR. Our findings describe the basic mechanism of FBD disease, right from sensing of phytoplasma infection by host plant triggering molecular signalling leading to mobilization of carbohydrate and protein, phyllody, abnormal pollen development, improved colonization of insect in host plants to spread the disease. Study reveals how phytoplasma hijacks metabolic machinery of soybean manifesting FBD.ConclusionsThis is the first report of transcriptomic signature of FBD or WBS disease of soybean revealing morphological and metabolic changes which attracts insect for spread of disease. All the genic region putative markers may be used as genomic resource for variety improvement and new agro-chemical development for disease control to enhance soybean productivity.Electronic supplementary materialThe online version of this article (10.1186/s12870-018-1601-1) contains supplementary material, which is available to authorized users.

“…According to statistics, reports of phytoplasma diseases are widespread worldwide, and they are common in temperate and tropical areas (Lee et al., 2000). According to statistics, phytoplasmas have damaged more than 1000 plant species (Hiruki & Wang, 2004; Seemüller & Schneider, 2004; Streten & Gibb, 2003), including food crops and oil crops (Jaiswal et al., 2019; Thorat et al., 2016), vegetables, fruit trees, garden wood, ornamental plants, feeds and weeds, causing great economic losses (Asudi et al., 2021; Bertaccini, 2007; Gurr et al., 2016; Maejima, Oshima, et al., 2014). Four major food crops, wheat, rice, maize and soybean, are susceptible to phytoplasma infection.…”

Phytoplasmas are phloem‐restricted plant‐pathogenic bacteria transmitted by insects. They cause diseases in a wide range of host plants, resulting in significant economic and ecological losses worldwide. Research on phytoplasmas has a long history, with significant progress being made in the past 30 years. Notably, with the rapid development of phytoplasma research, scientists have identified the primary agents involved in phytoplasma transmission, established classification and detection systems for phytoplasmas, and 243 genomes have been sequenced and assembled completely or to draft quality. Multiple possible phytoplasma effectors have been investigated, elucidating the molecular mechanisms by which phytoplasmas manipulate their hosts. This review summarizes recent advances in phytoplasma research, including identification techniques, host range studies, whole‐ or draft‐genome sequencing, effector pathogenesis and disease control methods. Additionally, future research directions in the field of phytoplasma research are discussed.
