It is notable for possessing male meiotic characteristics that are rarely observed in most angiosperms. However, the current understanding about male meiosis in Senecio remains incomplete. Here, we traced the cell morphological characteristics of microsporogenesis, and male gametophyte development of Senecio cannabifolius was observed by transmission electron microscopy. The results showed that the microspore mother cells were surrounded by callose; the cytokinesis was simultaneous; the tetrad was tetrahedral; and the mature pollen was two-celled pollen with three germination pores. During the meiosis of microspore mother cells, there were abundant organelles in the cytoplasm at leptotene stage. Obvious and clear synaptonemal complex was found in pachytene stage. In the prophase I stage, the number of organelles in the cytoplasm decreased; the cristae of mitochondria decreased; and the electron density of plastids was low. It began to recover at the metaphase I and formed an obvious organelle band in the anaphase I, which separated the two daughter nuclei and contained abundant organelles. During this period, the organelles in the cytoplasm changed regularly, which was the phenomenon of cytoplasmic reorganization. The pollen wall was formed at the late uninucleate stage; the pollen wall was mature at the binucleate microspore stage; and the pollen has abortion phenomenon. These results for the first time revealed the ultrastructure of microspores and male gametophytes during the development of S. cannabifolius and enriched the understanding of the formation of pollen grains by microspores in Compositae plants.</p>","PeriodicalId":20731,"journal":{"name":"Protoplasma","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The agamid beta-corneous layer is generally 3-4 times thicker than in geckos, and the surface microornamentation forms a honeycomb pattern. Geckos feature thinner beta-layers and a spinulated pattern and show immunolocalization for CBPs and isopeptide bonds, a product of transglutaminase catalysis, in their thin beta-layer. CBPs and isopeptide-bonds are detected in the superficial Oberhautchen and alpha-layer of agamids while the beta-layer is immuno-negative. Considering the limitations of immunolabeling methods, the unexpected result might derive from inaccessibility of antibodies to epitopes that are masked within the packed corneous material of the agamid beta-layer. However, bioinformatics analysis for CBPs sequenced in the few species of agamids so far known indicates that these proteins have low identity with those of other lizards. This suggests that agamids possess peculiar CBPs but low isopeptide bonds in their inflexible beta-layer. In contrast, the thinner and pliable beta-corneous layers of geckos may derive from the presence of isopeptide bonds mixed with lower amounts of CBPs.

Conventionally, herbicides are the site-specific weed inhibitors often used to suppress the growth of these weeds. Protoporphyrinogen oxidase (PPO) is an important target for developing novel herbicides with remarkable selectivity against these broad-leaved weeds. In particular, saflufenacil is a selective PPO herbicide that can provide temporary relief. However, their prolonged use could lead to various environmental constraints and the evolution of resistant weeds. Recently, bioherbicides are emerging as an alternative to commercial herbicides with safer environmental profiles and combat resistance. On that note, this study aimed to identify novel and safer bioherbicides derived from seaweeds to outright bans on the use of most synthetic herbicides and address herbicide resistance. High-end computational screening strategies including molecular docking, binding free energy, in-house developed ML-based VS, and herbicide-likeness were used to pinpoint the lead molecule against the wild and mutant (∆G210) type AtPPO. Finally, molecular dynamics simulations were employed to validate the binding kinetics of the hit compound. Indeed, the bromophenol derivative BL003, isolated from brown algae, emerged as the hit compound from our analysis. Remarkably, BL003 demonstrated superior binding affinity and stability compared to saflufenacil against both wild-type AtPPO and the mutant AtPPO<sup>ΔG210</sup>. Thus, our findings could open new avenues for developing sustainable, seaweed-derived herbicides for sorghum cultivation. This research could contribute to the ongoing efforts to create environmentally friendly weed management solutions in agriculture.</p>","PeriodicalId":20731,"journal":{"name":"Protoplasma","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known on the diversity of nectaries in the Bombacoideae subfamily. Pseudobombax argentinum presents two contrasting types of nectaries in the flower that were investigated for the first time using light, confocal laser and scanning electron microscopy, and field observations. Sepal nectaries are elevated glands on the abaxial side of the calyx tube. The exuded nectar was exclusively consumed by ants in the period between the flower bud development and the anthesis. The nectaries consist of secretory epidermis, nectary, and subnectary parenchyma. The two latter tissues are vascularized by phloem and xylem. Nectar release could occur both through the rupture of the cuticle or through the papillae. Histochemical tests indicated that secretions on the epidermis presented polysaccharides, pectins, and proteins. The second type of nectary corresponds to secreting areas on the external side of the staminal tube, which were active when the flower opening was initiated in the early evening and for 2 days. Bees and hummingbirds searched for this nectar in daylight hours. These nectaries are non-structural, with nectarostomata probably involved in the nectar release. Our findings suggest that the primary function of sepal nectaries is to attract and feed ants, while staminal nectaries play a role in rewarding pollinators. Both nectaries are non-trichomatous. The evaluation of variations in nectaries may be useful to determine evolutionary changes of this trait and its systematic importance. Thus, a comparison of nectary types across the Malvaceae groups is presented.</p>","PeriodicalId":20731,"journal":{"name":"Protoplasma","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
