Land plants (embryophytes) came about in a momentous evolutionary singularity: plant terrestrialization. This event marks not only the conquest of land by but also massive radiation embryophytes into diverse array novel forms and functions. The unique suite traits present earliest is thought to have been ushered burst genomic novelty. Here, we asked question how these bursts were possible. For this, explored: (i) initial emergence (ii) reshuffling domains give rise hallmark environmental response genes plants. We pinpoint that quarter embryophytic for stress physiology are specific lineage, yet significant portion this novelty arises de novo from recombining pre-existing domains. Our data suggest combinations old substrate shaped terrestrialization toolkit, including processes signalling, biotic interactions specialized metabolism.

Abstract Green algae display a wide range of extracellular matrix (ECM) components that include various types cell walls (CW), scales, crystalline glycoprotein coverings, hydrophobic compounds, and complex gels or mucilage. Recently, new information derived from genomic/transcriptomic screening, advanced biochemical analyses, immunocytochemical studies, ecophysiology has significantly enhanced refined our understanding the green algal ECM. In later diverging charophyte group algae, CW other ECM provide insight into evolution plants ways modulates during environmental stress. Chlorophytes produce diverse components, many which have been exploited for uses in medicine, food, biofuel production. This review highlights major advances studies algae.

Fruit pigments provide reproductive advantage for plant as well providing protection against unfavourable environmental conditions and pathogens. consumers these colours are considered attractive dietary benefits derived from fruits.

If factors intensify stress levels, tissues respond increasing (or ceasing) production. cases, if not severe, can have positive outcome Here, we focus on principal (light, temperature water) that influence colour.

Abstract The Streptophyta emerged about a billion years ago. Nowadays, this branch of the green lineage is most famous for one its clades, land plants (Embryophyta). Although Embryophyta make up major share species numbers in Streptophyta, there diversity probably >5000 streptophyte algae that form paraphyletic grade next to plants. Here, we focus on deep divergences gave rise streptophytes, hence particularly algae. Phylogenomic efforts have not only clarified position relative plants, but recent also begun unravel relationships and radiations within algal diversity. We illustrate how new phylogenomic perspectives changed our view evolutionary emergence key traits, such as intricate signalling networks are intertwined with multicellular growth chemodiverse hotbed from which they emerged.

Protecting haploid pollen and spores against UV-B light high temperature, 2 major stresses inherent to the terrestrial environment, is critical for plant reproduction dispersal. Here, we show flavonoids play an indispensable role in this process. First, identified flavanone naringenin, which serves defend damage, sporopollenin wall of all vascular plants tested. Second, found that flavonols are present spore/pollen protoplasm euphyllophyte tested these scavenge reactive oxygen species protect environmental stresses, particularly heat. Genetic biochemical analyses showed sequentially synthesized both tapetum microspores during ontogeny Arabidopsis (Arabidopsis thaliana). We stepwise increases complexity spores/pollen evolution mirror their progressive adaptation environments. The close relationship between flavonoid phylogeny its strong association with survival phenotypes suggest played a central progression from aquatic environments into progressively dry land habitats.

Pigmentation patterns are ubiquitous in nature. Visually striking pigmentation not only aesthetically appealing, but also crucial to pollinator interaction and plant fitness. The formation of complex floral mainly relies on the spatiotemporal expression R2R3-MYB transcription factors is often associated with certain development programs, such as organ identity, symmetry, which likely provide key information initiate patterning. For a pattern form, at least pair activator inhibitor required, despite their might vary depending system being investigated. regulation involves multiple molecular mechanisms, transcriptional regulation, small RNA, transposon-mediated gene silencing, methylation body. Identifying these regulators can be facilitated by using single-cell spatial transcriptomics well innovative transformation technologies. Moreover, interdependent, current methods describing static. Therefore, more precise quantitative measurements needed elucidate developmental mechanisms underlying flowers.

Abstract Duckweeds span 36 species of free-floating aquatic organisms with body sizes ranging from 2 mm to 10 mm, where each plant plan is reduced a largely leaf-like structure. As an emerging crop, their fast growth rates offer potential for cultivation in closed systems. We describe novel UK collection derived low light (dLL) or high (dHL) habitats, profiled growth, photosynthesis, and photoprotection (non-photochemical quenching, NPQ) responses. Twenty-three accessions three Lemna one Spirodela polyrhiza were grown under relatively (LL: 100 μmol m–2 s–1) (HL: 350 intensities. observed broad within- between-species level variation photosynthesis acclimation.

The zygnematophytes are the closest relatives of land plants and comprise several lineages that adapted to a life on land. Species genus Serritaenia form colorful, mucilaginous capsules, which surround cells block harmful solar radiation, one major terrestrial stressors. In eukaryotic algae, this 'sunscreen mucilage' represents unique photoprotective strategy, whose induction chemical background unknown. We generated de novo transcriptome testaceovaginata studied its gene regulation under moderate UV radiation (UVR) triggers sunscreen mucilage experimental conditions.
