Summary: In this study, seven CesA genes were identified and characterized in P. massoniana. Bioinformatics analysis showed that these putative CESA proteins consisted of typical motifs. Phylogenetic analysis revealed distinct functional groups of CesA genes in relation to regulating secondary wall synthesis and primary cell wall formation. RT-qPCR analysis demonstrated tissue-specific differential expression of CesA genes, as well as their induction by abiotic stress and hormones. Certain CesA genes were highly expressed in xylem and responsive to drought and salt stress induced by ABA, MeJA, ETH and SA hormones, indicating their role in the response to abiotic stress in P. massoniana.

Summary: The study identified six putative QTLs contributing to Fe-toxicity tolerance in rice and found that an introgression from O. meridionalis on chromosome 9 conferred high tolerance despite high shoot Fe concentrations. Physiological, biochemical, ionomic, and transcriptomic analyses revealed that the tolerance may be explained by higher relative Fe retention in the leaf sheath and culm. The interspecific hybrid genome analysis identified differentially regulated introgressed genes from O. meridionalis that could play a role in shoot-based Fe tolerance.

Summary: Dyckia brevifolia seedlings, a bromeliad native to Brazil, demonstrate tolerance to complete submergence by adopting the low oxygen quiescence syndrome strategy. They maintain chlorophyll and carotenoid contents, and efficiently detoxify reactive oxygen species, primarily hydrogen peroxide, during submergence periods. During the recovery period, these seedlings show fast-growth resumption, total soluble sugar recovery, and accumulation of chlorophyll and carotenoid.

Summary: Under natural conditions, plants face complex scenarios of combined or sequential environmental stresses. Antioxidant systems play a crucial role in the biochemical regulation of plants, including the interaction between specialized metabolites and central pathways. The metabolic responses of Psychotria brachyceras Mull Arg., an alkaloid accumulating plant, were analyzed under individual, sequential, and combined stress conditions. Different stress application schemes had varying effects on alkaloid accumulation, proline, and carotenoids, constituting a complementary triad of antioxidants. This study provides insights that can aid in developing a framework for stress responses and their balance to enhance tolerance and yield of specialized metabolites.

Summary: Tropane alkaloids are specialized plant metabolites found mainly in the Erythroxylaceae and Solanaceae families. Despite their structural similarities due to the tropane ring, they exhibit distinct pharmacological actions. Studies on the Erythroxylum species in Brazil, especially Erythroxylum pungens, have identified potential chemical markers like 3-(2-methylbutyryloxy)tropan-6,7-diol, which showed behavioral effects in zebrafish models. The alkaloid also demonstrated potential in affecting antidepressant pathways, highlighting its possible use in treating depression-like symptoms.
