Comparative analysis of chloroplast genomes and phylogenetic relationships in the endemic Chinese bamboo (Bambusoideae).

Introduction: Wen is a small yet taxonomically challenging genus within the Arundinarieae tribe. Recent molecular studies have suggested it may not be monophyletic. However, limited species sampling and insufficient molecular marker information have resulted in poorly resolved phylogenetic relationships within this genus.

Spatiotemporal transcriptome atlas reveals gene regulatory patterns during the organogenesis of the rapid growing bamboo shoots.

Bamboo with its remarkable growth rate and economic significance, offers an ideal system to investigate the molecular basis of organogenesis in rapidly growing plants, particular in monocots, where gene regulatory networks governing the maintenance and differentiation of shoot apical and intercalary meristems remain a subject of controversy. We employed both spatial and single-nucleus transcriptome sequencing on 10× platform to precisely dissect the gene functions in various tissues and early developmental stages of bamboo shoots. Our comprehensive analysis reveals distinct cell trajectories during shoot development, uncovering critical genes and pathways involved in procambium differentiation, intercalary meristem formation, and vascular tissue development.

Complete chloroplast genome sequence and phylogenetic analysis of (Bambusoideae).

is an ornamental shrubby bamboo endemic to southern China. In this study, the complete chloroplast genome (cpDNA) sequence of was first reported. The cpDNA is 139,594 bp in length, including a small single-copy (SSC) region of 12,820 bp and a large single-copy (LSC) region of 83,196 bp, which were separated by a pair of inverted repeat (IR) regions of 21,789 bp.

The complete chloroplast genome sequence of (Bambusoideae: Arundinarieae): a shrubby bamboo endemic to China.

The complete chloroplast genome sequence of , firstly determined here, is 139,705 bp in length, inclusive of a pair of inverted repeat (IR, 21,817 bp) regions separated by a small single copy (SSC, 12,803 bp) and a large single copy (LSC, 83,268 bp). It contains 132 genes, such as 85 CDS, 8 rRNA genes, and 39 tRNA genes, respectively. The phylogenetic analysis shows that is highly clustered in the clade (III) of Arundinarieae, sister to the clade of .

Complete chloroplast genome of a rare deciduous tree species, (Magnoliaceae).

The complete chloroplast genome of a rare deciduous tree species with ornamental value, , was first determined. It was 160,170 bp in length, including a pair of inverted repeat (IR, 26,567 bp) regions separated by a small single copy (SSC, 18,842 bp) sequence and a large single copy (LSC, 88,194 bp) sequence. The chloroplast genome contained 132 genes, consisting of 87 CDS, 8 rRNA genes, and 37 tRNA genes.

The making of elaborate petals in Nigella through developmental repatterning.

Elaborate petals are present in many flowering plants lineages and have greatly promoted the success and evolutionary radiation of these groups. How elaborate petals are made, however, remains largely unclear. Petals of Nigella (Ranunculaceae) have long been recognized as elaborate and can thus be an excellent model for the study of petal elaboration.

Gains and Losses of Cis-regulatory Elements Led to Divergence of the Arabidopsis APETALA1 and CAULIFLOWER Duplicate Genes in the Time, Space, and Level of Expression and Regulation of One Paralog by the Other.

How genes change their expression patterns over time is still poorly understood. Here, by conducting expression, functional, bioinformatic, and evolutionary analyses, we demonstrate that the differences between the Arabidopsis (Arabidopsis thaliana) APETALA1 (AP1) and CAULIFLOWER (CAL) duplicate genes in the time, space, and level of expression were determined by the presence or absence of functionally important transcription factor-binding sites (TFBSs) in regulatory regions. In particular, a CArG box, which is the autoregulatory site of AP1 that can also be bound by the CAL protein, is a key determinant of the expression differences.

Flexibility in the structure of spiral flowers and its underlying mechanisms.

Spiral flowers usually bear a variable number of organs, suggestive of the flexibility in structure. The mechanisms underlying the flexibility, however, remain unclear. Here we show that in Nigella damascena, a species with spiral flowers, different types of floral organs show different ranges of variation in number.

Disruption of the petal identity gene APETALA3-3 is highly correlated with loss of petals within the buttercup family (Ranunculaceae).

Absence of petals, or being apetalous, is usually one of the most important features that characterizes a group of flowering plants at high taxonomic ranks (i.e., family and above).
