genes constitute a large family of transcription factors that play important roles in plant growth and development. However, our understanding of genes involved in anther development and male sterility in is still limited. In this study, 63 genes were identified from the genome of the male sterility ecotype Sichuan (_SC) unevenly distributed among eight chromosomes. Phylogenetic analysis classified them into two types and 17 subfamilies. They contained 1 to 12 exons and 10 conserved motifs. Evolution analysis showed that segmental duplication was the main force for the expansion of the gene family, and duplication gene pairs were under purifying selection. Cis-acting elements analysis demonstrated that the promoter of genes contain numerous elements associated with plant growth and development, plant hormones, and stress response. RNA-seq showed that the expression levels of B-class and C-class genes were highly expressed during anther development, with likely playing an important role in regulating anther development and male fertility in _SC. Overall, this study provides a comprehensive analysis of the gene family in , shedding light on their potential role in anther development and male sterility.

Background: The relationships between floral traits and pollinators have been extensively studied over the last few decades. The concept of pollination syndrome suggests that plants pollinated by the same group of pollinators tend to develop similar combinations of floral traits. However, several studies have demonstrated the low predictability of these trait combinations and found high levels of pollination generalization within plant communities.

PhasiRNAs (phased small interfering RNAs) are a major class of plant small RNAs (sRNA) known to be key regulators in male reproductive development of maize (Zea mays) and rice (Oryza sativa), among other plants. Earlier research focused primarily on premeiotic 21-nucleotide (nt) phasiRNAs and meiotic 24-nt phasiRNAs, while new studies uncovered a premeiotic class of 24-nt phasiRNAs. The biogenesis and function of these phasiRNAs remain unclear.

The Gα subunit RGA1, a crucial component of heterotrimeric G proteins, has been well-documented to enhance drought resistance in rice seedlings. However, its role during the reproductive stages has remained unexplored. This study aimed to investigate the function of RGA1 in mitigating drought-induced defects in anther and pollen development during pollen mother cell meiosis with Zhonghua 11 (WT), a Gα-deficient mutant (d1), and an RGA1-overexpressing line (OE-1).

Abiotic stresses increasingly threaten wheat ( L.) productivity by impairing pollen development and fertilization, yet the molecular regulators that coordinate reproductive success with environmental resilience remain underexplored. Here, we present a comprehensive genome-wide analysis of the Pollen I (POEI) protein family in common wheat.

Background And Aims: Evolutionary floral modifications that enable plants to exploit particular body parts of animals for pollen transfer are considered a key contributor to the angiosperm radiation. Species of Dilatris (Haemodoraceae) have an unusual combination of floral traits including a centrally-positioned stamen with a large anther flanked by two stamens with smaller anthers (heteranthery), and styles that are deflected either to the right or left on flowers of the same plant (monomorphic enantiostyly). We investigated the pollination functions of these traits in D.
