Genome-Wide Identification, Evolution, and Expression Analysis of the <i>TCP</i> Gene Family in Rose (<i>Rosa chinensis</i> Jacq.) by Yi Hou, Chunguo Fan, Jingrui Sun, Yufei Chang, Jun Lu, Jingjing Sun, Changquan Wang, Jinyi Liu

“…Furthermore, the expression levels of <i>RcTCPs</i> under vegetative and reproductive growth and drought stress treatments were analyzed based on public RNA-seq dataset, and it was shown that <i>RcTCPs</i> exhibited serious tissue-specific expression, with most of them dominantly expressed in flowers, leaves and stems, with high levels of expression at different stages of flower and bud differentiation, particularly during petal formation and gametophyte development. The high inducement of seven <i>RcTCP</i> genes from PCF class in drought stress indicated their important roles in biological processes against drought stress. …”

Changes in m6A RNA methylation are associated with male sterility in wolfberry by Jiawen Zhao, Chujun Zhang, Sifan Li, Mengmeng Yuan, Wenlan Mu, Jing Yang, Yutong Ma, Cuiping Guan, Chuang Ma

“…We found the hypermethylated genes significantly enriched in biological processes related to energy metabolism and lipid metabolism, while hypomethylation genes were mainly linked to cell cycle process, gametophyte development, and reproductive process. Among these 2205 differentially m6A methylated genes, 13.74% (303 of 2205) were differentially expressed in LB1 vis-à-vis LB5. …”

Glycosylphosphatidylinositol-anchored proteins as chaperones and co-receptors for FERONIA receptor kinase signaling in Arabidopsis by Chao Li, Fang-Ling Yeh, Alice Y Cheung, Qiaohong Duan, Daniel Kita, Ming-Che Liu, Jacob Maman, Emily J Luu, Brendan W Wu, Laura Gates, Methun Jalal, Amy Kwong, Hunter Carpenter, Hen-Ming Wu

“…Here we report that the female gametophyte-expressed glycosylphosphatidylinositol-anchored protein (GPI-AP) LORELEI and the seedling-expressed LRE-like GPI-AP1 (LLG1) bind to the extracellular juxtamembrane region of FER and show that this interaction is pivotal for FER function. …”

Cytological Observation and Transcriptome Comparative Analysis of Self-Pollination and Cross-Pollination in <i>Dendrobium Officinale</i> by Yaling Chen, Benchang Hu, Fantao Zhang, Xiangdong Luo, Jiankun Xie

“…Results for self-pollination showed that the pollen tubes could grow in the style at 2 h, but most of pollen tubes stopped growing at 4 h, while a large number of cross-pollinated pollen tubes grew along the placental space to the base of ovary, indicating that the self-incompatibility of <i>D. officinale</i> may be gametophyte self-incompatibility. A total of 63.41 G basesum of <i>D. officinale</i> style samples from non-pollinated, self-pollination, and cross-pollination by RNA-seq were obtained, and a total of 1944, 1758, and 475 differentially expressed genes (DEGs) in the comparison of CK (non-pollinated) vs. …”

Antibacterial Activities and Life Cycle Stages of <i>Asparagopsis armata</i>: Implications of the Metabolome and Microbiome by Christelle Parchemin, Delphine Raviglione, Anouar Mejait, Pierre Sasal, Elisabeth Faliex, Camille Clerissi, Nathalie Tapissier-Bontemps

“…Several studies have reported differences in targeted halogenated compounds (using gas chromatography–mass spectrometry analysis (GC-MS)) and antibacterial activities between the tetrasporophyte and the gametophyte stages. To enlarge this picture, we analysed the metabolome (using liquid chromatography–mass spectrometry (LC-MS)), the antibacterial activity and the bacterial communities associated with several stages of the life cycle of <i>A. armata</i>: gametophytes, tetrasporophytes and female gametophytes with developed cystocarps. …”

Hydrogen Peroxide and GA₃ Levels Regulate the High Night Temperature Response in Pistils of Wheat (<i>Triticum aestivum</i> L.) by Purbali Mukherjee, Pavithra Suriyakumar, S. Vanchinathan, Veda Krishnan, Milan Kumar Lal, Prakash Kumar Jha, Viswanathan Chinnusamy, Anjali Anand, P. V. Vara Prasad

“…High night temperature (HNT) impairs crop productivity through the reproductive failure of gametes (pollen and pistil). Though female gametophyte (pistil) is an equal partner in the seed-set, the knowledge of the antioxidant system(s) and hormonal control of HNT tolerance or susceptibility of pistils is limited and lacking. …”

Quantifying baseline costs and cataloging potential optimization strategies for kelp aquaculture carbon dioxide removal by Struan Coleman, Tobias Dewhurst, David W. Fredriksson, Adam T. St. Gelais, Kelly L. Cole, Michael MacNicoll, Eric Laufer, Damian C. Brady, Damian C. Brady

“…To resolve these challenges, R&amp;D must (1) de-risk farm designs that maximize lease space, (2) automate the seeding and harvest processes, (3) leverage selective breeding to increase yields, (4) assess the cost-benefit of gametophyte nursery culture as both a platform for selective breeding and driver of operating cost reductions, (5) decarbonize equipment supply chains, energy usage, and ocean cultivation by sourcing electricity from renewables and employing low GHG impact materials with long lifespans, and (6) develop low-cost and accurate MRV techniques for ocean-based CDR.…”

Seed size, endosperm and germination variation in sexual and apomictic Boechera by Dorota Paczesniak, Dorota Paczesniak, Marco Pellino, Marco Pellino, Richard Goertzen, Devan Guenter, Siegfried Jahnke, Andreas Fischbach, John T. Lovell, Timothy F. Sharbel, Timothy F. Sharbel

“…Apomictic seeds were not more uniform in size than sexual seeds, despite genetic uniformity of the maternal gametophyte in the former. Among specific embryo/endosperm ploidy combinations, seeds with tetraploid (automomous) endosperm were on average smaller, and the proportion of such seeds was highest in apomicts. …”

Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae by Alok Arun, Susana M Coelho, Akira F Peters, Simon Bourdareau, Laurent Pérès, Delphine Scornet, Martina Strittmatter, Agnieszka P Lipinska, Haiqin Yao, Olivier Godfroy, Gabriel J Montecinos, Komlan Avia, Nicolas Macaisne, Christelle Troadec, Abdelhafid Bendahmane, J Mark Cock

“…We demonstrate that mutations in either of two TALE HD TF genes, OUROBOROS or SAMSARA, in the brown alga Ectocarpus result in conversion of the sporophyte generation into a gametophyte. The OUROBOROS and SAMSARA proteins heterodimerise in a similar manner to TALE HD TF life cycle regulators in the green lineage. …”

Closed life-cycle aquaculture of sea lettuce (Ulva fenestrata): performance and biochemical profile differ in early developmental stages by Sophie Steinhagen, Karin Larsson, Joakim Olsson, Eva Albers, Ingrid Undeland, Henrik Pavia, Gunilla B. Toth

“…The life-history of Ulva alternates between a diploid sporophytic life-stage and a haplontic gametophytic life-stage. Whereas the sporophyte give raise to recombinant gametophytes through zoids, gametophytes can give raise to parthenogenetically developing, clonal gametes in absence of a mating partner. …”
