Salicylic acid (SA), an essential plant hormone, has received much attention due to its role in modulating the adverse effects of biotic and abiotic stresses, acting as antioxidant growth regulator. However, photosynthesis under non stress conditions is controversial. By chlorophyll fluorescence imaging analysis, we evaluated consequences foliar applied 1 mM SA on photosystem II (PSII) efficiency tomato (Solanum lycopersicum L.) plants estimated reactive oxygen species (ROS) generation. Tomato leaves sprayed with displayed lower content, but absorbed light energy was preferentially converted into photochemical rather than dissipated thermal by non-photochemical quenching (NPQ), indicating photoprotective provided SA. This decreased NPQ, after 72 h treatment SA, resulted increased electron transport rate (ETR). The molecular mechanism which more efficiently directed photochemistry treated fraction open PSII reaction centers (qp), (Fv'/Fm'). induced a decrease resulting non-regulated (ΦNO) high (HL) treatment, suggesting amount triplet excited state (3Chl*) molecules available produce singlet (1O2). Yet, efficiency, compared control, evolving complex (OEC) donor side PSII, associated formation hydrogen peroxide (H2O2), also contributed less creation ROS. We conclude that conditions, content suppressed phototoxicity, offering photoprotection; thus, it can be regarded reduces photoinhibition photodamage, improving crop plants.

Abstract Salicylic acid (SA) is an important phytohormone, well‐known for its regulatory role in shaping plant immune responses. In recent years, significant progress has been made unravelling the molecular mechanisms underlying SA biosynthesis, perception, and downstream signalling cascades. Through concerted efforts employing genetic, biochemical, omics approaches, our understanding of SA‐mediated defence responses undergone remarkable expansion. general, following biosynthesis through Avr effectors pathogens, newly synthesized undergoes various biochemical changes to achieve active/inactive forms (e.g. methyl salicylate). The activated subsequently triggers pathways associated with perception pathogen‐derived signals, expression genes, induction systemic acquired resistance (SAR) tailor intricate networks that coordinate Nonetheless, mechanistic regulation currently limited because crosstalk other networks, which makes this hormone more challenging. This comprehensive review aims provide integrated overview immunity, deriving current knowledge from diverse research outcomes. integration case studies, experimental evidence, emerging trends, offers insights into governing immunity signalling. Additionally, discusses potential applications strategies crop improvement, disease management, sustainable agricultural practices.

Lateral roots (LRs), are an important component of plant roots, playing a crucial role in anchoring the soil and facilitating uptake water nutrients. As post-embryonic organs, LRs originate from pericycle cells primary root, their formation is characterized by precise regulation cell division complex intercellular interactions, both which closely tied to wall regulation. Considering rapid advances molecular techniques over past three decades, we reframe understanding dynamic change during LR development summarizing factors that precipitate these changes effects, as well regulated signals involved.

Abstract Airspace or aerenchyma is crucial for plant development and acclimation to stresses such as hypoxia, drought, nutritional deficiency. Although ethylene-mediated signaling cascades are known regulate formation in stems roots under hypoxic conditions, the precise mechanisms remain unclear. Moreover, cellular dynamics underlying airspace shoots poorly understood. We investigated stage-dependent structural of shoot greater duckweed (Spirodela polyrhiza), a fast-growing aquatic herb with well-developed its floating fronds. Using X-ray micro-computed tomography histological analysis, we showed that spatial framework established before frond volume increases, driven by cell division expansion. The substomatal cavity connecting stomata formed via programmed death (PCD) was closely associated guard development. Additionally, transcriptome analysis pharmacological studies revealed organization determined interplay between PCD proliferation. This balance governed spatiotemporal regulation phytohormone involving ethylene, abscisic acid, salicylic acid. Overall, our study reveals phytohormonal duckweed, improving understanding how plants establish distinct architectural arrangements. These insights hold potential wide-ranging application, not only comprehending across various species but also airspaces within leaves terrestrial plants.
