Effect of temperature and daylength on the phenological development of oats (Avena sativa L.)
… influence the time of panicle development on the shoot apex, panicle emergence, anthesis and grain-filling which contribute to crop yield and quality. The objective of the research presented in this thesis was to investigate the influence of temperature and daylength on the phenological …

AN HMA DOMAIN-CONTAINING PROTEIN NaKR1 REGULATES LONG-DISTANCE FLORIGEN MOVEMENT IN ARABIDOPSIS THALIANA
… SIGNALING TO INDUCE FLOWERING AT THE SHOOT APEX. IN A. THALIANA, PART OF THE MOBILE FLOWERING SIGNALS CALLED FLORIGEN HAS BEEN IDENTIFIED AS THE FLOWERING LOCUS T (FT) PROTEIN, WHICH IS INDUCED BY THE NUCLEAR PROTEIN CONSTANS (CO) IN RESPONSE TO LONG-DAY (LD) CONDITIONS. HERE WE REPORT …

Effects of disbudding, defoliating, tipping, and pruning on young, potted apple trees
… in a greenhouse and trained to a single shoot. When shoot length averaged 73 cm, the following treatments were applied: a) check, untreated (CK); b) tipped (shoot apex removed) and top 1/2 of shoot disbudded (T-DB); c) top 1/2 of shoot disbudded and defoliated (UT-DB-DF); d) tipped, and …

Investigating the Roles of Three Aintegumenta-Like Genes In Maintenance of Arabidopsis Shoot Meristem Activity
<p>The shoot apical meristem, a small dome-shaped structure at the shoot apex of higher plants, is established during development of the embryo. After germination, the indeterminate activity of the shoot apical meristem is responsible for the initiation of all aboveground parts of the plant. The …

Mathematical modelling of the floral transition — with a Bayesian flourish —
… a clue on spatial patterning of an Arabidopsis shoot apex. Incorporating network knowledge into a plant breeding program is an exciting goal for future developments addressing global food security.

The role of auxin transport in the control of shoot branching
… to environmental stimuli. In flowering plants, shoot branching is regulated through the activity of axillary buds, which grow into branches. Several classes of plant hormones have been shown to play pivotal roles in regulating bud outgrowth. Auxin derived from the primary shoot apex and active …

Spatio-temporal analysis of florigenic signals in Arabidopsis thaliana, Sinapis alba and Brassica napus
… but how the floral signal is transduced to the shoot apex via the phloem to induce flowering remains to be elucidated. This study aimed at the identification of new candidates involved in the induction of flowering by employing three plant species, Arabidopsis thaliana, Sinapis alba and Brassica …

Spatiotemporal Interaction Networks in Plant Development
… de novo vascular differentiation in the shoot apical meristem, regulation of cell polarity, and quantitative analysis of spatial gene expression. First, we deployed genetic, in vivo imaging and computational studies to derive an auxin-initiated feedback network of transcription factors …

Description and control of flowering in California Poppy (Eschscholzia californica)
… in the apical cells, an enhanced doming of the shoot apex, an increased elongation of primordia internodes, a disruption of the tunica-corpus organization, and the appearance of well-developed branch primordia. Eight to ten LD cycles was identified as the critical range required for successful …

Regulating Inositol Biosynthesis in Plants: Myo-Inositol Phosphate Synthase and Myo-Inositol Monophosphatase
… promoter causes expression at the base of the shoot apex and within leaflets of the first set of fully expanded leaves. Further, <I>Leimp</I>-2 promoter expression was localized to epidermal and cortex cells on the abaxial side of the 1st and 2nd fully expanded compound leaves. These studies of …

The contribution of repeat associated small RNAs to genetic variation, hybrid vigor and inbreeding depression in maize
… (B73 x Mo17). We sampled sRNAs from the seedling shoot apex and the developing ear, two rapidly growing tissues that program the greater growth of maize hybrids. </p> <p> In plants, sRNAs can be grouped into three functionally distinct classes based on their lengths of 21, 22, or 24 nucleotides …
