“…MAC3A and MAC3B (MOS4-associated complex 3A/B) are functionally redundant plant proteins which have so far mostly been studied for their role in miRNA biogenesis and plant immunity (Monaghan et al, 2009;Li et al, 2018). They co-immunoprecipitate with both SMB and the evolutionarily conserved SNW/SKI INTERACTING PROTEIN (SKIP) that is associated with the spliceosome through its interaction with SR45 (Wang et al, 2012;Li et al, 2016Li et al, , 2019Cao and Ma, 2019).…”

Alternative splicing occurs in all eukaryotic organisms. Since the first description of multiexon genes and the splicing machinery, the field has expanded rapidly, especially in animals and yeast. However, our knowledge about splicing in plants is still quite fragmented. Though eukaryotes show some similarity in the composition and dynamics of the splicing machinery, observations of unique plant traits are only starting to emerge. For instance, plant alternative splicing is closely linked to their ability to perceive various environmental stimuli. Due to their sessile lifestyle, temperature is a central source of information allowing plants to adjust their development to match current growth conditions. Hence, seasonal temperature fluctuations and day-night cycles can strongly influence plant morphology across developmental stages. Here we discuss the available data about temperature-dependent alternative splicing in plants. Given its fragmented state it is not always possible to fit specific observations into a coherent picture, yet it is sufficient to estimate the complexity of this field and the need of further research. Better understanding of alternative splicing as a part of plant temperature response and adaptation may also prove to be a powerful tool for both, fundamental and applied sciences.

“…SNW domain in SKIP protein regulate pre-mRNA splicing and also was identified as a transcription factor of gene transcription activator in Paf1 complex, which is involved in transcription of FLOWERING LOCUS C and flowering in A. thaliana (10). It is involved in alternative splicing regulation of clock and salt tolerance-related genes in plants (141).…”

Impatiens is a genus containing more than 1000 species. Thanks to its size, it is a unique system for studying species diversification in natural populations. This study focused on the characterization of novel transcriptomes from seven Impatiens species originating from Nepal. Leave transcriptome of Impatines balsamina L. , I. racemosa DC. , I. bicornuta Wall , I. falcifer Hook , I. devendrae Pusalkar, I. scullyi Hook and I. scabrida DC were sequenced and compared. Reads were de novo assembled and aligned to 92 035-226 081 contigs. We identified 14 728 orthology groups shared among all the species and 3 020 which were unique to a single species. In single species, 2536-3009 orthology groups were under selection from which 767 were common for all species. Six of the seven investigated species shared 77% of gene families with I. bicornuta being the most distinct species. Specific gene families involved in response to different environmental stimuli were closely described. Impatiens bicornuta selection profile shared selection on zing finger protein structures and flowering regulation and stress response proteins with the other investigated species. Overall, the study showed substantial similarity in patterns of selections on transcribed genes across the species suggesting similar evolutionary pressures. This suggests that the species group may have evolved via adaptive radiation.

“…STM physically associates with various proteins to regulate meristem activity (Figure 3a). One is the SKI-INTERACTING PROTEIN (SKIP), a protein conserved in eukaryotes that regulates plant gene expression through both transcription regulation and mRNA splicing [32]. STM and SKIP can bind directly to the promoters of multiple STM target genes, and SKIP is proposed to act as an STM cofactor that recruits components of the transcriptional machinery, such as the RNA polymerase-associated factor 1 complex (Paf1c), to STM target genes to sustain SAM pluripotency [33].…”

The development of both animals and plants relies on populations of pluripotent stem cells that provide the cellular raw materials for organ and tissue formation. Plant stem cell reservoirs are housed at the shoot and root tips in structures called meristems, with the shoot apical meristem (SAM) continuously producing aerial leaf, stem, and flower organs throughout the life cycle. Thus, the SAM acts as the engine of plant development and has unique structural and molecular features that allow it to balance self-renewal with differentiation and act as a constant source of new cells for organogenesis while simultaneously maintaining a stem cell reservoir for future organ formation. Studies have identified key roles for intercellular regulatory networks that establish and maintain meristem activity, including the KNOX transcription factor pathway and the CLV-WUS stem cell feedback loop. In addition, the plant hormones cytokinin and auxin act through their downstream signaling pathways in the SAM to integrate stem cell activity and organ initiation. This review discusses how the various regulatory pathways collectively orchestrate SAM function and touches on how their manipulation can alter stem cell activity to improve crop yield.
