“…Previous studies have reported that changes in lipid composition help in maintaining membrane integrity and preserve cellular compartmentation under various abiotic stress conditions (Masuda et al 1981;Gigon et al 2004;Rienth et al 2014). Moreover, lipid-derived endogenous hormone, JA also regulates various stress responses in plants (Bhatla 2018). Ahmed et al (2019) reported that JA biosynthesis mutant had a larger foliar stomatal aperture than wild-type genotypes of Cryptocoryne elliptica under salinity stress, indicating positive regulation of guard cells by JA.…”

Extensive transcriptomic skimming was conducted to decipher molecular, morphological, physiological, and biochemical responses in salt-tolerant (PDL-1) and salt-sensitive (L-4076) cultivars under control (0 mM NaCl) and salinity stress (120 mM NaCl) conditions at seedling stage. Morphological, physiological, and biochemical studies revealed that PDL-1 exhibited no salt injury and had higher K + / Na + ratio, relative water content (RWC), chlorophyll, glycine betaine, and soluble sugars in leaves while lower H 2 O 2 induced fluorescence signals in roots as compared to L-4076. Transcriptomic profile revealed a total of 17,433 significant differentially expressed genes (DEGs) under different treatments and cultivar combinations that include 2557 upregulated and 1533 downregulated transcripts between contrasting cultivars under salt stress. Accuracy of transcriptomic analysis was validated through quantification of 10 DEGs via quantitative real-time polymerase chain reaction (qRT-PCR). DEGs were functionally characterized by Gene Ontology (GO) analysis and assigned to various metabolic pathways using MapMan. DEGs were found to be significantly associated with phytohormone-mediated signal transduction, cellular redox homoeostasis, secondary metabolism, nitrogen metabolism, and cellular stress signaling. The present study revealed putative molecular mechanism of salinity tolerance in lentil together with identification of 5643 simple sequence repeats (SSRs) and 176,433 single nucleotide polymorphisms (SNPs) which can be utilized to enhance linkage maps density along with detection of quantitative trait loci (QTLs) associated with traits of interests. Stress-related pathways identified in this study divulged plant functioning that can be targeted to improve salinity stress tolerance in crop species.

“…The Mg deficiency led to a lower dry mass, smaller leaf area, and a low number of leaves than in the control (Table 2), possibly because of a reduction in chlorophyll content and alteration of carbon fixation necessary for plant growth and development (Guo et al, 2016). The Mg deficiency might have also caused an alteration in enzyme activity, such as for RuBisCO involved in the reactions of photosynthesis, in which Mg acts as a cofactor (Bhatla and Lal, 2018). The smaller contents of chlorophyll can be associated with the reduction in its synthesis and oxidative damage by reactive oxygen species that degrade chlorophyll molecule, decreasing photosynthesis rates and, thus, leaf growth and biomass production (Tanoi and Kobayashi, 2015).…”

“…The plants with Ca deficiency had a lower production of dry matter and lower leaf area (Table 2) since, under this condition, cell elongation might be limited because cell walls were weaker because Ca interchangeably joins R-COO − groups of polygalacturonic acids and is required to stimulate the synthesis of cell wall precursors (Marschner, 2012;Thor, 2019). The reduction of growth and leaf deformation are the symptoms typical of that deficiency, explained by the low mobility of Ca in plants and the alteration of properties of cell walls and membranes (Bhatla and Lal, 2018).…”

The purple passion fruit (Passiflora edulis Sims f. edulis) is a promising crop in Colombia because of its high potential for international markets and high profitability. However, without adequate fertilization, the metabolic processes of plant growth can be affected. The objective of this research was to evaluate the effect of macro-and micronutrient deficiencies on growth, photosynthesis, and transpiration in purple passion fruit plants during vegetative development. Seedlings with four to six leaves (three-months-old) were transplanted to a sand culture and subjected to mineral deficiencies using the missing element technique under greenhouse conditions. The plants subjected to Fe deficiency had the lowest maximum photosynthetic rate at saturation by light (1.72 µmol CO 2 m −2 s −1) at 72 days after treatment, while the lowest apparent quantum efficiency (0.008 µmol CO 2 µmol photons −1) was observed in the plants with Mg deficiency. The lowest values of maximum photochemical efficiency of photosystem II, Fv/Fm (0.69) and transpiration rate (2.39 µg H 2 O cm −2 s −1) were found in the plants with P deficiency. The mineral nutrient deficiencies negatively affected metabolic processes in the purple passion fruit plants, with the highest impact on photosynthesis observed with the Fe or Mg deficiencies. The plants subjected to P deficiencies were the most affected plants in terms of transpiration rate.

Backround: Spathodea campanulata P. Beauv., exhibits a phenomenal structure often referred to as water calyces from within which the entire floral whorls presumed to be developing. Purpose: The present study was an attempt on the exceptional development of corolla under the influence of the bathing fluid of water calyces in Spathodea campanulata. Method: Three different developmental stages of flower buds were used for anatomical, physiological (PWC, RWC and ᴪW) and biochemical studies (reducing sugars, amino acids, proteins, phenols, IAA and amylase activity) using standard methods. Results: Biochemical composition was found to be directly influencing the unique pattern of floral ontogeny. The exponential expansion of the corolla was found to be corresponding with significant increase in IAA concentration. Conclusions: The bathing fluid with its contents viz., sugars, amino acids, proteins, IAA and phenols seems to play a pivotal role in the development, nourishing and protecting the inner whorls of the flower buds. Anatomical studies also support the idea that the biochemical changes, especially the quantity of sugars and IAA could be the reason for the exponential expansion of the petals.
