Point mutations were introduced into specific leucine (L) amino acids within the K domain of SHORT VEGETATIVE PHASE (SVP), and their effects on the SVP-AP1 interaction were assessed. Yeast two-hybrid experiments and β-galactosidase activity assays demonstrated that SVP maintained its capacity to interact with APETALA1 (AP1) despite point mutations at the 108th, 116th, 119th, and 127th leucine residues, where leucine was substituted with alanine (A). However, the mutation of the leucine residue at position 124 to alanine abolished the interaction between SVP and AP1 regardless of whether the mutation was singular or combined with others.

Species of the complex cause postbloom fruit drop of citrus and anthracnose fruit rot of strawberries. produces acervuli in diseased citrus flowers and strawberry fruit, surviving asymptomatically on vegetative tissues. Previous studies have suggested that dispersal mechanisms other than windblown rain may be involved in dispersal of conidia of sensu lato.

DNA N6-methyladenine (6mA) is a potential epigenetic mark involved in gene transcription in eukaryotes, yet the regulatory mechanism governing its methyltransferase (MTase) activity remains obscure. Here, we exploited the 6mA MTase AMT1 to elucidate its auto-regulation in the unicellular eukaryote Tetrahymena thermophila. The detailed endogenous localization of AMT1 in vegetative and sexual stages revealed a correlation between the 6mA reestablishment in the new MAC and the occurrence of zygotically expressed AMT1.

In filamentous fungi, some NLRs mediate heterokaryon incompatibility, a self/non-self recognition process that prevents the vegetative fusion of genetically distinct individuals, reducing the risk of parasitism. The and NLRs in are highly polymorphic incompatibility genes ( genes) whose products recognize different alleles of the gene via a sensor domain composed of WD40 repeats.

Polyethylene nanoplastics (NPs) are widely diffused in terrestrial environments, including soil ecosystems, but the stress mechanisms in plants are not well understood. This study aimed to investigate the effects of two increasing concentrations of NPs (20 and 200 mg kg of soil) in lettuce. To this aim, high-throughput hyperspectral imaging was combined with metabolomics, covering both primary (using NMR) and secondary metabolism (using LC-HRMS), along with lipidomics profiling (using ion-mobility-LC-HRMS) and plant performance.
