We propose that hormones can spend time ‘outside the plant’ in soil as ‘rhizocrine’ signals whose levels change following environmental stresses, feeding back to roots and triggering adaptive responses.

This review summarizes achievements of selective events in the pollination process, which are crucial for species specificity in cruciferous plants.

Enzymatic antioxidants cannot be used as a proxy for stress tolerance or as a target for crop genetic improvement due to interference with stress signalling by reactive oxygen species.

This review outlines the use of marker-assisted breeding to develop a high-yielding and nutritious elite millet germplasm using advanced genomics tools, omics techniques, and systems biology approaches.

This review focuses on the knowledge gap between the upstream transcriptional regulators and the downstream cellular machinery driving changes in cell division orientation in the Arabidopsis root apical meristem.

Subgroup VIII receptor-like cytoplasmic kinases are catalytically inactive and function in Arabidopsis immune signaling.

Through in vivo capturing of nuclear proteins undergoing S -sulfenylation, we identified redox-active nuclear proteins, including the histone acetyltransferase GCN5. We highlight the functionality of particular GCN5 cysteines by cysteine-to-serine mutagenesis.

This study analyses physiological and transcriptomic differences in two mango varieties, identifying key metabolic pathways and the role of nutrient import in enhancing ‘off’ year flowering.

The major candidate gene controlling anthocyanin acylation in blueberry skin was functionally validated, and the relative causative variant identified, providing invaluable information for developing cultivars with enhanced fruit quality.

This study identifies shared genetic regulators and interconnected loci influencing plant architectural and biomass yield traits, enabling the pyramiding of favorable alleles for advancing bioenergy sorghum breeding efforts.

In Taraxacum type diplospory, asexual reproduction is dominant over the sexual pathway. The DIPLOSPOROUS locus controls chromosome dynamics during MMC meiosis, without severely altering the expression of crucial meiotic genes.

Early podding is necessary for high chickpea harvest index; this requires early flowering, which is influenced by the genotypic photoperiod response, and preventing conditions that cause pod abortion.

We demonstrate that PPD-H1 exhibits true pleiotropic effects on spike fertility, in addition to those related to the lengthening of flowering time.

The sensitive Ppd-H1 line reduced fertility in distal spikelets, while the insensitive ppd-H1 promoted development in less-favored florets and even induced more progress before floret death in apical spikelets.

The ethylene-induced transcription factor RhHB22 inhibits expression of GDP-l-galactose phosphorylase 1 and ascorbic acid production, leading to reactive oxygen species accumulation and accelerated petal senescence in rose.

The lectin receptor kinase LecRK-I.9 regulates the molecular events leading to lateral root formation in both the initiation and emergence processes in Arabidopsis through cell wall remodelling enzymes and signalling peptides.

The regulatory module BZR1/BES1–CEP1 partially functions downstream of protein phosphatase 2A in promoting pollen wall construction.

OPS/OPL genes regulate Arabidopsis growth; some directly by modulating meristem activity, others indirectly via phloem differentiation, highlighting their broad role as key positive plant growth regulators.

Sirodesmin PL, the principal toxin produced by Leptosphaeria maculans , induces cell death and defense mechanisms in Brassica napus , disrupting photosynthesis and facilitating the infection process.

Turgor pressure modulates the mechanical properties of poricidal anthers, influencing pollen release dynamics and highlighting the interplay between environmental conditions, anther mechanics, and buzz pollination behaviors.

In a FACE experiment, e[CO₂ ] enhanced photosynthesis in ryegrass, and this difference increased with days since watering. Conversely, the reduction in stomatal conductance under e[CO₂ ] declined with days since watering, with implications for soil moisture depletion.

A blueprint method facilitates the selection and analysis of small RNAs from the beneficial fungus Serendipita indica , demonstrating their involvement in Arabidopsis gene silencing and suggesting their translocation during mutualistic interaction.
