Transcriptional Regulation of Pine Male and Female Cone Initiation and Development: Key Players Identified Through Comparative TranscriptomicsGENETIC transcription regulationCONESPINEFEMALESMALESPINACEAECONIFERSWith long reproductive timescales, large complex genomes, and a lack of reliable referen...
To solve the question regarding the occurrence of male and female cones in Pinus, we can follow these steps:1. Understand the Structure of Pinus: - Pinus, commonly known as pine trees, has distinct male and female cones. Th
The terms "male" and "female," when used to describe trees, fit as awkwardly as someone else's shoes. Although the flowers of flowering trees (the angiosperms) and the cones of conifers (the most prominent of the gymnosperms) need to be fertilized with pollen to produce f...

the female cones are larger and longer-lived than the male cones. The megasporangia or ovules are borne on the upper surface of the megasporophylls, often in pairs. Inside each ovule, a single megaspore mother cell undergoes meiosis to produce four haploid cells, of which only one survives...
4.1 Male and Female Gametophyte Development Gametogenesis in angiosperms proceeds in the protected surroundings provided by the flower. The female gametophyte (FG) develops within the ovule, the male gametophyte (MG) within the anther primordia. Connections between FG development and phosphorelay signaling...
The molecular regulation of induction and development of reproductive organs is well established in angiosperms, while it is slowly accumulating in gymnosperms. Here, we conducted comparative transcriptomic profiles at different stages of male and female cone development inPinus halepensis. Our aim was ...
2. Materials and Methods 2.1. Plant Materials Pinus bungeana is a monoecious conifer species, which produces male and female cones during March–May. Three male and three female conelets (female conelet 1, female conelet 2, female conelet 3, male conelet 1, male conelet 2, and male ...
In angiosperms this pollen is located in the anther and in gymnosperms it is located on the pine cones or pollen cones. How are male gametes formed in plants? Male gametes are formed in the anther of angiosperms, the archegonial head of liverworts and moss, and the pollen cones of ...
