“…In particular, CBF III and LEA group 3 clades are members of generic stress response gene families that are rapidly cold‐induced and that duplicated at the base of, and more locally within, Pooideae (this study; Sandve & Fjellheim, ; Li et al ., ; Liu et al ., ). Closely related paralogs in the CBF IV clade are cold‐inducible in the subtropical grasses rice (Ehrhartoideae; OsDREB1H , OsDREB1B and OsDREB1A ) and Cynodon dactylon (Chloridoideae) (Dubouzet et al ., ; Chen et al ., ), and the core Pooideae cereals wheat and barley (Badawi et al ., ; Stockinger et al ., ).…”

Likewise, a LEA group 3 ortholog in the tropical grass maize is involved in low‐temperature responses (Liu et al ., ). These data collectively suggest functional diversification of CBF III and IV and LEA group 3 genes or differential partitioning of an ancestral cold‐responsive function following gene duplication and regulatory changes.…”

Successive evolutionary steps drove Pooideae grasses from tropical to temperate regions

et al. 2017

Angiosperm adaptations to seasonally cold climates have occurred multiple times independently. However, the observation that less than half of all angiosperm families are represented in temperate latitudes suggests internal constraints on the evolution of cold tolerance/avoidance strategies. Similar to angiosperms as a whole, grasses are primarily tropical, but one major clade, subfamily Pooideae, radiated extensively within temperate regions. It is posited that this Pooideae niche transition was facilitated by an early origin of long-term cold responsiveness around the base of the subfamily, and that a set of more ancient pathways enabled evolution of seasonal cold tolerance. To test this, we compared transcriptome-level responses of disparate Pooideae to short-/long-term cold and with those previously known in the subtropical grass rice (Ehrhartoideae). Analyses identified several highly conserved cold-responsive 'orthogroups' within our focal Pooideae species that originated successively during the diversification of land plants, predominantly via gene duplication. The majority of conserved Pooideae cold-responsive genes appear to have ancient roles in stress responses, with most of the orthogroups also being sensitive to cold in rice. However, a subgroup of genes was likely co-opted de novo early in the Pooideae. These results highlight a plausible stepwise evolutionary trajectory for cold adaptations across Pooideae.

The disadvantages of being a hybrid during drought: A combined analysis of plant morphology, physiology and leaf proteome in maize

et al. 2017

A comparative analysis of various parameters that characterize plant morphology, growth, water status, photosynthesis, cell damage, and antioxidative and osmoprotective systems together with an iTRAQ analysis of the leaf proteome was performed in two inbred lines of maize (Zea mays L.) differing in drought susceptibility and their reciprocal F1 hybrids. The aim of this study was to dissect the parent-hybrid relationships to better understand the mechanisms of the heterotic effect and its potential association with the stress response. The results clearly showed that the four examined genotypes have completely different strategies for coping with limited water availability and that the inherent properties of the F1 hybrids, i.e. positive heterosis in morphological parameters (or, more generally, a larger plant body) becomes a distinct disadvantage when the water supply is limited. However, although a greater loss of photosynthetic efficiency was an inherent disadvantage, the precise causes and consequences of the original predisposition towards faster growth and biomass accumulation differed even between reciprocal hybrids. Both maternal and paternal parents could be imitated by their progeny in some aspects of the drought response (e.g., the absence of general protein down-regulation, changes in the levels of some carbon fixation or other photosynthetic proteins). Nevertheless, other features (e.g., dehydrin or light-harvesting protein contents, reduced chloroplast proteosynthesis) were quite unique to a particular hybrid. Our study also confirmed that the strategy for leaving stomata open even when the water supply is limited (coupled to a smaller body size and some other physiological properties), observed in one of our inbred lines, is associated with drought-resistance not only during mild drought (as we showed previously) but also during more severe drought conditions.

“…BTF3 was previously reported to be involved in the transcription initiation by RNA polymerase II as well as in apoptosis. A recent study also demonstrated that silencing BTF3 expression in wheat through virus-induced gene silencing resulted in a more severe viral symptoms and reduced biomass (Liu et al 2016). LEA is known as a hydrophilic protein acting as a molecular chaperone to stabilize proteins, vesicles, and endomembrane (Gal et al 2004).…”

Alfalfa (Medicago sativa L.) is an important forage crop and is also a target of many fungal diseases including Fusarium spp. As of today, very little information is available about molecular mechanisms that contribute to pathogenesis and defense responses in alfalfa against Fusarium spp. and specifically against Fusarium proliferatum, the causal agent of alfalfa root rot. In this study, we used a proteomic approach to identify inducible proteins in alfalfa during a compatible interaction with F. proliferatum strain YQC-L1. Samples used for the two-dimensional gel electrophoresis (2-DE) and MALDI-TOF/TOF mass spectrometry were from roots and leaves of alfalfa cultivar AmeriGraze 401+Z and WL656HQ. Plants were grown in hydroponic conditions and at 4 days post inoculation with YQC-L1. Our disease symptom assays indicated that AmeriGraze 401+Z was tolerant to YQC-L1 infection while WL656HQ was highly susceptible. Analysis of differentially expressed proteins found in the 2-DE was further characterized using the MASCOT MS/MS ion search software and associated databases to identify multiple proteins that might be involved in F. proliferatum resistance. A total of 66 and 27 differentially expressed proteins were found in the roots and leaves of the plants inoculated with YQC-L1, respectively. These identified proteins were placed in various categories including defense and stress response related metabolism, photosynthesis and protein synthesis. Thirteen identified proteins were validated for their expressions by quantitative reverse transcription (qRT)-PCR. Our results suggested that some of the identified proteins might play important roles in alfalfa resistance against Fusarium spp. These finding could facilitate further dissections of molecular mechanisms controlling root rot disease in alfalfa and potentially other legume crops.
