Red seaweeds are key components of coastal ecosystems and economically important as food a source gelling agents, but their genes genomes have received little attention. Here we report the sequencing 105-Mbp genome florideophyte Chondrus crispus (Irish moss) annotation 9,606 genes. The features an unusual structure characterized by gene-dense regions surrounded repeat-rich dominated transposable elements. Despite its fairly large size, this shows typical compact genomes, e.g., on average...
The brown alga Ectocarpus siliculosus has a haploid–diploid life cycle that involves an alternation between two distinct generations, the sporophyte and gametophyte. We describe mutant, ouroboros ( oro ), in which generation is converted into functional, gamete-producing history of mutant thus consists continuous reiteration gametophyte generation. exhibited morphological features typical accumulated transcripts marker genes. Genetic analysis showed behaved as single, recessive, Mendelian...
Three amino acid loop extension homeodomain transcription factors (TALE HD TFs) act as life cycle regulators in green algae and land plants. In mosses these are required for the deployment of sporophyte developmental program. We demonstrate that mutations either two TALE TF genes, OUROBOROS or SAMSARA, brown alga Ectocarpus result conversion generation into a gametophyte. The SAMSARA proteins heterodimerise similar manner to lineage. These observations TALE-HD-TF-based regulation systems...
Summary The model brown alga Ectocarpus has a haploid‐diploid life cycle, involving alternation between two independent multicellular generations, the gametophyte and sporophyte. Recent work shown that of generations is not determined by ploidy but rather under genetic control, at least one master regulatory locus, OUROBOROS ( ORO ). Using cell biology approaches combined with measurements generation‐specific transcript abundance we provide evidence can also be regulated non‐cell autonomous...
The molecular mechanisms that underlie dental fluorosis are poorly understood. retention of enamel proteins hallmarking fluorotic may result from impaired hydrolysis and/or removal proteins. Previous studies have suggested partial inhibition Mmp20 expression is involved in the etiology fluorosis. Here we ask if mice expressing only one functional allele more susceptible to We demonstrate Mmp20+/− express approximately half amount MMP20 as do wild-type mice. heterozygous normal-appearing...
Abstract Rhoeo spathacea is unusual in that its twelve chromosomes are involved complex translocations results atypical meiosis with all frequently joined end-to-end into a single ring. The detailed meiotic studies, for the first time, revealed alignment of ring and / or chain begins at very early prophase I. However, cells diakinesis metaphase I do not exclusively have 12 chromosomes. Instead, they carry range configurations formed due to slipping chiasmata off pairing segments structures....
The life cycle of an organism is one its most elemental features, underpinning a broad range phenomena including developmental processes, reproductive fitness, mode dispersal and adaptation to the local environment. Life modification may have played important role during evolution several eukaryotic groups, terrestrial plants. Brown algae are potentially interesting models study because this group exhibits different cycles. Currently, studies focused on emerging brown algal model Ectocarpus....
Real-time quantitative reverse transcription PCR (qRT-PCR) is a technique widely used to quantify the transcriptional expression level of candidate genes. qRT-PCR requires selection one or several suitable reference genes, whose profiles remain stable across conditions, normalize Although butterfly species (Lepidoptera) have become important models in molecular evolutionary ecology, so far no study aimed at identifying genes for accurate data normalization any available. The African bush...
The genus Musa spp. contains commercially important fleshy fruit producing plants including plantains and bananas with a strong potential of providing food security source revenue to farmers. Occasionally, plantlets are often not available fulfill the supply demand farmers particularly in Caribbean region. Concerns quality vegetative tissues along possibility transmission phytopathogens makes availability limited farm-ers. Micropropagation offers an alternative large number in-vitro...
Arracacia xanthorrhiza is an important secondary food crop in South America and Puerto Rico. The lack of protection improvement strategies leads to infections damaging the storage roots. Here, we report annotated complete chloroplast genome sequence A. as a step toward developing genomic resources for this crop.
ABSTRACT Here, we report a draft metagenome-assembled genome and annotation of Pseudomonas sp. obtained from the sequenced Vaucheria bursata . The completeness was 97.9% with total 5,322 open reading frames, which 3,147 genes were annotated. availability metagenome will elucidate possible epiphytic interactions bacteria
The genus Musa sp. contains commercially important fleshy fruit-producing plants, including plantains and bananas, with a strong potential for providing food security sources of revenue to farmers. Concerns the quality vegetative tissues along possibility transmission phytopathogens makes availability healthy plantlets limited Micropropagation offers an alternative producing large numbers plantlets. However, conventional methods micropropagation have high production costs are...
Paulownia (Paulownia elongata) is a fast-growing, multipurpose deciduous hardwood species that grows in wide range of temperatures from –30 °C to 45 °C. Seasonal cues influence the secondary growth tree stems, including cambial activity, wood chemistry, and transition latewood formation. In this study, de novo transcriptome approach was conducted identify transcripts expressed vascular tissue senescent winter actively growing spring seasons. An Illumina paired-end sequenced generated...
We report the development of in vitro propagation protocols through an adventitious shoot induction pathway for a rare and medicinal Scutellaria havanensis. In studies using nodal explants showed MS medium supplemented with 10 µM 6-Benzylaminopurine induced highest number shoots time-dependent manner. A ten-day incubation was optimum bud as longer exposures resulted hyperhydricity induced. also preliminary evidence Agrobacterium tumefaciens EHA105-mediated gene transfer transiently...
