Main conclusionABA and GA metabolism during incubation rather than hormone contents in dry seeds is the key to understanding secondary dormancy and germination of Syngonanthus verticillatus seeds.AbstractThe mechanism of seed dormancy cycle, although very important for preventing germination during unfavorable periods for seedling establishment, is...

Main conclusionTartary buckwheat rice-type cultivars, which allow easy dehulling, lacked periclinal cell divisions that proceed underneath the epidermis in the proximity of ovary midribs in non-rice-type cultivars. The easy dehulling in these cultivars was associated with a G→A substitution in an AGAMOUS ortholog.AbstractEase of dehulling in Tartar...

Main conclusionIn response to low nitrogen stress, multiple hormones together with nitric oxide signaling pathways work synergistically and antagonistically in crop root elongation.AbstractChanging root morphology allows plants to adapt to soil nutrient availability. Nitrogen is the most important essential nutrient for plant growth. An important a...

Main ConclusionPlant growth-promoting bacteria association improved the enzymatic and non-enzymatic antioxidant pathways in Neotropical trees under drought, which led to lower oxidative damage and enhanced drought tolerance in these trees.AbstractWater deficit is associated with oxidative stress in plant cells and may, thus, negatively affect the e...

Main conclusionThe review provides information on the mechanisms underlying the development of spontaneous and pathogen-induced tumors in higher plants. The activation of meristem-specific regulators in plant tumors of various origins suggests the meristem-like nature of abnormal plant hyperplasia.AbstractPlant tumor formation has more than a centu...

Main conclusionA comprehensive account of the LBD gene family of Gossypium was provided in this work. Expression analysis and functional characterization revealed that LBD genes might play different roles in G. hirsutum and G. barbadense.AbstractThe Lateral Organ Boundaries Domain (LBD) proteins comprise a plant-specific transcription factor family...

Main conclusionGenome-wide analysis of small RNAs identifies somatic embryogenesis- specific miRNAs and their targets and provides novel insights into the mechanisms governing somatic embryogenesis in coconut, a highly in vitro recalcitrant species.AbstractCoconut, a major plantation crop of the tropics is recalcitrant to in vitro culture with a ve...

Main conclusionA hypothesis that squalene cyclase genes are widely distributed throughout ferns was proposed. We successfully isolated a squalene cyclase pseudogene from a fern from which no triterpene hydrocarbons were detectedAbstractFerns are the most primitive vascular plants, with their locations ranging from tropical to cold temperate regions...

Main conclusionDysfunctional mutation of OsNDPK4 resulted in severe defects in root development of rice. However, the resistance of Osndpk4 against bacterial blight was significantly enhanced.AbstractNucleoside diphosphate kinases (NDPKs) are an evolutionarily conserved family of important enzymes balancing the energy currency nucleoside triphospha...
