Auxins and gibberellins in embryonic shoots of Scots pine in relation to flower sex differentiation
Flower sex differentiation in Scots pine is correlated with endogenous balance of auxins to gibberellins. Male flower primordia initiation is connected with high amounts of gibberellins whereas the initiation of female ones is associated with a high ...

The effect of auxins in inducing organogenesis or somatic embryogenesis in mature sunflower zygotic embryo derived apex [PDF]
Induction of shoots or of somatic embryos is the key step for gaining the morphogenetic potential in sunflower (Helianthus annuus L.), species known as recalcitrant to in vitro regeneration.

Auxin regulates a host of plant developmental and physiological processes, including embryogenesis, vascular differentiation, organogenesis, tropic growth, and root and shoot architecture. Genetic and biochemical studies carried out over the past decade have revealed that much of this regulation involves the SCF(TIR1/AFB)-mediated proteolysis of the ...

Auxin action and auxin‐binding proteins [PDF]
SUMMARYThe plant growth regulator auxin mediates an enormous range of developmental and growth responses, some of which are manifest rapidly and others manifest only after considerable lag periods. The protein that perceives auxin, the auxin receptor, has been sought by many laboratories and the search has identified a good number of candidates ...

The history of plant biology is inexorably intertwined with the conception and discovery of auxin, followed by the many decades of research to comprehend its action during growth and development. Growth responses to auxin are complex and require the coordination of auxin production, transport, and perception. In this overview of past auxin research, we

Defining binding efficiency and specificity of auxins for SCFTIR1/AFB-Aux/IAA co-receptor complex formation [PDF]
Structure–activity profiles for the phytohormone auxin have been collected for over 70 years, and a number of synthetic auxins are used in agriculture. Auxin classification schemes and binding models followed from understanding auxin structures. However,

Polar Auxin Transport and Asymmetric Auxin Distribution [PDF]
Introduction: In all multicellular organisms extensive communication is required between cells and tissues in order to coordinate growth and development. Both plants and animals have signaling chemicals, traditionally termed hormones that mediate short- and long-distance communication. The first phytohormone to be discovered was auxin, a substance that

Development of 4-methoxy-7-nitroindolinyl (MNI)-caged auxins which are extremely stable in planta [PDF]
Phytohormone auxin is a master regulator in plant growth and development. Regulation of cellular auxin level plays a central role in plant development. Auxin polar transport system modulates an auxin gradient that determines plant developmental process ...
