The Evolution of HD2 Proteins in Green Plants
- 2016
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 21:12, s. 1008-1016
-
Research review (peer-reviewed)abstract
- In eukaryotes, protein deacetylation is carried out by two well-conserved his tone deacetylase (HDAC) families: RPD3/HDA1 and SIR2. Intriguingly, model plants such as Arabidopsis express an additional plant-specific HDAC family, termed type-2 HDACs (HD2s). Transcriptomic analyses from more than 1300 green plants generated by the 1000 plants (1KP) consortium showed that HD2s appeared early in green plant evolution, the first members being detected in several streptophyte green alga. The HD2 family has expanded via several rounds of successive duplication; members are expressed in all major green plant clades. Interestingly, angiosperm species express new HD2 genes devoid of a zinc-finger domain, one of the main structural features of HD2s. These variants may have been associated with the origin and/or the biology of the ovule/seed.

Mitophagy : A Mechanism for Plant Growth and Survival
- 2018
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385. ; 23:5, s. 434-450
-
Journal article (peer-reviewed)abstract
- Mitophagy is a conserved cellular process that is important for autophagic removal of damaged mitochondria to maintain a healthy mitochondrial population. Mitophagy also appears to occur in plants and has roles in development, stress response, senescence, and programmed cell death. However, many of the genes that control mitophagy in yeast and animal cells are absent from plants, and no plant proteins marking defunct mitochondria for autophagic degradation are yet known. New insights implicate general autophagy-related proteins in mitophagy, affecting the senescence of plant tissues. Mitophagy control and its importance for energy metabolism, survival, signaling, and cell death in plants are discussed. Furthermore, we suggest mitochondrial membrane proteins containing ATG8-interacting motifs, which might serve as mitophagy receptor proteins in plant mitochondria.

Do Plants Eavesdrop on Floral Scent Signals?
- 2016
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 21:1, s. 9-15
-
Research review (peer-reviewed)abstract
- Plants emit a diverse array of volatile organic compounds that can function as cues to other plants. Plants can use volatiles emitted by neighbors to gain information about their environment, and respond by adjusting their phenotype. Less is known about whether the many different volatile signals that plants emit are all equally likely to function as cues to other plants. We review evidence for the function of floral volatile signals and conclude that plants are as likely to perceive and respond to floral volatiles as to other, better-studied volatiles. We propose that eavesdropping on floral volatile cues is particularly likely to be adaptive because plants can respond to these cues by adjusting traits that directly affect pollination and mating.

Auxin Metabolism Controls Developmental Decisions in Land Plants
- 2019
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 24, s. 741-754
-
Research review (peer-reviewed)abstract
- Unlike animals, whose body plans are set during embryo development, plants maintain the ability to initiate new organs throughout their life cycle. Auxin is a key regulator of almost all aspects of plant development, including morphogenesis and adaptive responses. Cellular auxin concentrations influence whether a cell will divide, grow, or differentiate, thereby contributing to organ formation, growth, and ultimately plant shape. Auxin gradients are established and maintained by a tightly regulated interplay between metabolism, signalling, and transport. Auxin is synthesised, stored, and inactivated by a multitude of parallel pathways that are all tightly regulated. Here we summarise the remarkable progress that has been achieved in identifying some key components of these pathways and the genetic complexity underlying their precise regulation.

CO2 Sensing and CO2 peculation of Stomatal Conductance: Advances and Open Questions
- 2016
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 21, s. 16-30
-
Research review (peer-reviewed)abstract
- Guard cells form epidermal stomatal gas-exchange valves in plants and regulate the aperture of stomatal pores in response to changes in the carbon dioxide (CO2) concentration ((CO2]) in leaves. Moreover, the development of stomata is repressed by elevated CO2 in diverse plant species. Evidence suggests that plants can sense [CO2] changes via guard cells and via mesophyll tissues in mediating stomata! movements. We review new discoveries and open questions on mechanisms mediating CO2-regulated stomatal movements and CO2 modulation of stomatal development, which together function in the CO2 regulation of stomatal conductance and gas exchange in plants. Research in this area is timely in light of the necessity of selecting and developing crop cultivars that perform better in a shifting climate.

Green Bioplastics as Part of a Circular Bioeconomy
- 2019
-
In: Trends in Plant Science. - : Elsevier. - 1360-1385 .- 1878-4372. ; 24:3, s. 237-249
-
Research review (peer-reviewed)abstract
- The rapid accumulation of plastic waste is driving international demand for renewable plastics with superior qualities (e.g., full biodegradability to CO2 without harmful byproducts), as part of an expanding circular bioeconomy. Higher plants, microalgae, and cyanobacteria can drive solar-driven processes for the production of feedstocks that can be used to produce a wide variety of biodegradable plastics, as well as bioplastic-based infrastructure that can act as a long-term carbon sink. The plastic types produced, their chemical synthesis, scaled-up biorefinery concepts (e.g., plant-based methane-to-bioplastic production and co-product streams), bioplastic properties, and uses are summarized, together with the current regulatory framework and the key barriers and opportunities.

Protists: Puppet Masters of the Rhizosphere Microbiome
- 2019
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 24, s. 165-176
-
Research review (peer-reviewed)abstract
- The rhizosphere microbiome is a central determinant of plant performance. Microbiome assembly has traditionally been investigated from a bottom-up perspective, assessing how resources such as root exudates drive microbiome assembly. However, the importance of predation as a driver of microbiome structure has to date largely remained overlooked. Here we review the importance of protists, a paraphyletic group of unicellular eukaryotes, as a key regulator of microbiome assembly. Protists can promote plant-beneficial functions within the microbiome, accelerate nutrient cycling, and remove pathogens. We conclude that protists form an essential component of the rhizosphere microbiome and that accounting for predator-prey interactions would greatly improve our ability to predict and manage microbiome function at the service of plant growth and health.

Diversifying Food Systems in the Pursuit of Sustainable Food Production and Healthy Diets
- 2017
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 22, s. 842-856
-
Research review (peer-reviewed)abstract
- Increasing demand for nutritious, safe, and healthy food because of a growing population, and the pledge to maintain biodiversity and other resources, pose a major challenge to agriculture that is already threatened by a changing climate. Diverse and healthy diets, largely based on plant-derived food, may reduce diet-related illnesses. Investments in plant sciences will be necessary to design diverse cropping systems balancing productivity, sustainability, and nutritional quality. Cultivar diversity and nutritional quality are crucial. We call for better cooperation between food and medical scientists, food sector industries, breeders, and farmers to develop diversified and nutritious cultivars that reduce soil degradation and dependence on external inputs, such as fertilizers and pesticides, and to increase adaptation to climate change and resistance to emerging pests.

Lancrace Germplasm for Improving Yield and Abiotic Stress Adaptation
- 2016
-
In: Trends in Plant Science. - : Elsevier BV. - 1360-1385 .- 1878-4372. ; 21, s. 31-42
-
Journal article (peer-reviewed)abstract
- Plant landraces represent heterogeneous, local adaptations of domesticated species and thereby provide genetic resources that meet current and new challenges for farming in stressful environments. These local ecotypes can show variable phenology and low to moderate edible yield, but are often highly nutritious. The main contributions of landraces to plant breeding have been traits for a more efficient nutrient uptake and utilization, as well as useful genes for adaptation to stressful environments, such as water stress, salinity and high temperatures. We propose that a systematic landrace evaluation that may define patterns of diversity, which will facilitate identifying alleles for enhancing yield and abiotic stress adaptation, thus raising the productivity and stability of staple crops in vulnerable environments.
