“…Some species produce phytochemicals with antimicrobial activity and thus have both ornamental and prophylactic value [ 1 , 26 ]. Furthermore, Bougainvillea species are drought-tolerant, with a range of ecotypes including spiny trees, shrubs, and vines that enable plants to adapt to different geographical areas [ 17 , 71 ]. One of the most important ornamental traits of Bougainvillea is the brilliant bract color, which is thought to occur as the result of betalain accumulation ( Fig.…”

Bougainvillea is a perennial ornamental shrub that is highly regarded in ornamental horticulture around the world. However, the absence of genome data limits our understanding of the pathways involved in bract colouration and breeding. Here, we report a chromosome-level assembly of the giga-genome of Bougainvillea × buttiana ‘Mrs. Butt’, a cultivar thought to be the origin of many other Bougainvillea cultivars. The assembled genome is ~5 Gb with a scaffold N50 of 151,756,278 bp and contains 86,572 genes which undergone a recent WGD. We confirmed that multiple rounds of whole genome multiplication have occurred in the evolutionary history of the Caryophyllales, reconstructed the relationship in the Caryophyllales at whole genome level, and found discordance between species and gene trees as the result of complex introgression events. We investigated betalain and anthocyanin biosynthetic pathways and found instances of independent evolutionary innovations in the nine different Caryophyllales species. To explore the potential formation mechanism of diverse bract colours in Bougainvillea, we analyzed the genes involved in betalains and anthocyanins biosynthesis and found extremely low expression of ANS and DFR genes in all cultivars, which may limit anthocyanin biosynthesis. Our findings indicate that the expression pattern of the betalain biosynthetic pathway did not directly correlate with the bract colour, and the higher expression level in the betalain biosynthetic pathway is required for the coloured bract. The improved understanding of the correlation between gene expression and bract colour allows plant breeding outcomes to be predicted with greater certainty.

“…Their demand is increasing throughout the year due to their attractive colour, shape, size and good keeping quality as reported by Bharathkumar et al, [1]. It is a major source of carotenoid pigment for poultry industry to provide the yellow colour of egg yolk and is also an antagonistic crop in controlling the nematode population was investigated by Gupta [2]. Marigold is easy to cultivate and show wider adaptability to the environment.…”

An investigation entitled “Standardization of cost-effective nursery techniques in Marigold (Tagetes sp)” was conducted at Horticultural College and Research Institute, Coimbatore during the year 2020-2021. The experiment was conducted in Completely Randomized Design (CRD) with three replications and six treatments. Terminal cuttings of marigold was taken as the propagating material and it was raised in three types of containers viz., coco plugs, non-woven plug and protray filled with different combinations of media like cocopeat, vermicompost, VAM and Bacillus subtilis. Observations were recorded on survival percentage, vegetative parameters, branching and rooting parameters after 15th and 30th day of planting. Among all the treatments, the treatment T2 (Non-woven plug + Cocopeat + Vermicompost + VAM + Bacillus subtilis) showed the best results among the growth characteristics.

A pot culture experiment was conducted at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University during 2021-2022 to study the response of integrated zinc and iron management practices on biochemical attributes and nutrient uptake of marigold cv. Local Orange. The experiment was laid out in completely randomized design (CRD) with eight treatments and three replications. The eight treatments included an untreated control (T1), 100% Recommended dose of fertilizer (RDF) (T2) , RDF + FYM enriched with ZnSO4 and FeSO4 @ 10 and 15 kg ha-1 respectively (T3), RDF + FYM enriched with ZnSO4 and FeSO4 @ 15 and 20 kg ha-1 respectively (T4), RDF + FYM enriched with ZnSO4 and FeSO4 @ 20 and 25 kg ha-1 respectively (T5), RDF + foliar spray of ZnSO4 and FeSO4 each @ 0.5% (T6), RDF + foliar spray of ZnSO4 and FeSO4 @ 0.5 and 1.0 % respectively (T7), RDF + foliar spray of liquid multi micronutrient @ 1.0 % (T8). The application of integrated zinc and iron was observed to exhibit a significant effect on growth, yield, biochemical attributes and nutrient uptake. Maximum total chlorophyll content in leaf (mg g-1) and nutrient uptake was observed with the application of RDF + foliar spray of ZnSO4 and FeSO4 each @ 0.5% (T6) while regarding biochemical attributes viz., total carotenoid content in petals (mg g-1) and total phenols (mg g-1) maximum was observed with the application of RDF + foliar spray of liquid multi micronutrient @ 1.0 % (T8) which contains the proper amount of zinc and iron.
