Summary: A novel and effective direct shoot regeneration technique was developed for the medicinal plant Coleus forskohlii. Meta-Topolin was found to be more efficient than BAP in promoting direct organogenesis. The regeneration process showed distinct phases of shoot formation. The developed protocol can be used for the commercial production of C. forskohlii.

Summary: Salt stress has a severe impact on plant growth and development. Understanding the mechanisms related to growth and development in response to salt stress is crucial for plant tolerance and adaptation. This paper highlights the roles of microRNAs, redox status, reactive oxygen species, nitric oxide, and phytohormones in apical meristems for salt tolerance, as well as the relationship between salt stress response and stem cell homeostasis.

Summary: Recent studies have revealed the critical role of the feedback loop between WUS and CLV3 in maintaining the stem cell niche in the shoot apical meristem of plants. WUS promotes stem cell fate and is inhibited by CLV3, ensuring the stability of this niche. Furthermore, WUS can integrate both internal and external cues to enable the shoot meristem to adapt to various environmental changes.

Summary: Organogenesis in plants relies on a balance between cell division and expansion, with the root serving as an ideal model to study cell proliferation. Cell proliferation activity is mainly restricted to the root apical meristem, and a combination of new tools, experimental strategies, and mathematical models has enhanced our understanding of cell proliferation in the RAM. Further research is needed to explore additional aspects of cell proliferation in plants.

Summary: The shoot apical meristem of Arabidopsis thaliana displays a memory of non-lethal heat stress, enabling it to recover growth after a lethal heat stress. RNA sequencing identified genes involved in establishing this heat stress transcriptional memory. Heat shock transcription factor A2 is essential for regulating the expression of memory genes in SAM.

Summary: Endocytosis is important for plant response to stimuli and TPC plays an essential role in endocytosis in Arabidopsis plants. Knockout or knockdown of TPC subunits cause severe phenotypes, but partially functional alleles cause mild deviations. Reduced TPC-dependent endocytosis leads to hypersensitivity to CLAVATA3 peptide signaling.

Summary: A stable mutant of rapeseed with the multi-stem trait was discovered, showing abnormal shoot apical meristem development and increased main stem number compared to the wild type. Histological and scanning electron microscopy analysis revealed multiple shoot apical meristems in the mutant, while only one was found in the wild type. Transcriptome analysis showed significant changes in gene expression involved in cytokinin biosynthesis and metabolism pathways in the mutant. These findings provide insights into the mechanism of multi-main-stem formation in Brassica napus L. and establish a theoretical foundation for breeding multi-main-stem rapeseed vegetable varieties.

Summary: The shoot apical meristem is a crucial reservoir of stem cells in plants, with its size regulated by a balance of stem cell replenishment and cell incorporation into organ primordia. The WUS/CLV negative feedback loop plays a central role in SAM size regulation, depending on accurate spatial expression of WUS and CLV3. A signaling pathway involving ERf receptors and EPFL ligands restricts SAM width and promotes leaf initiation by inhibiting the expression of WUS and CLV3 in the periphery and confining them to the center of the SAM.

Summary: Microscopy techniques were used to locate the symbiont belonging to the orders Chaetothyriales and Pleosporales in seeds and plant sections. The symbiont was found in various tissues of the seeds and different parts of the plant. The mycelia of the symbiont were closely associated with specific types of trichomes. These findings provide further understanding of the relationship between the seed transmitted Chaetothyriales symbiont and Ipomoea carnea.

Summary: This study identified quantitative trait loci (QTL) for various agro-morphological and phosphorus-content traits in finger millet under low phosphorus (LP) and high phosphorus (HP) conditions using linkage mapping. A total of 55 QTL associated with agro-morphological and phosphorus-content traits were detected under LP conditions, and 37 QTL were detected under HP conditions. Biotic and abiotic stress-responsive candidate genes linked to some of the QTL were also identified. These findings can be utilized in breeding programs to develop finger millet with better phosphorus use efficiency and improve the lives of poor farmers.

Summary: Humans consume plant-based foods in their daily life, but contamination of agricultural soils by heavy metals poses a major food and nutritional security issue. Crop plants grown in HM-contaminated soils can accumulate heavy metals in their edible parts, which can lead to health issues in humans. Researchers aim to reduce non-essential heavy metals and improve essential heavy metals in crop plants through phytoremediation and biofortification, with genetic components playing a critical role in these strategies.

Summary: Deficiencies of phosphorus and zinc have a significant impact on finger millet, affecting plant biomass, root hair modification, nutrient uptake, and molecular responses. While phosphorus deficiency has a greater effect on biomass reduction compared to zinc deficiency, the combined deficiency of both phosphorus and zinc leads to an increase in root hair length and density. Phosphorus deficiency promotes zinc uptake, and zinc deficiency promotes phosphorus uptake. This study provides valuable insights for better management of phosphorus and zinc deficiency in finger millet.
