    Shugufta Parveen1, Fayaz A. Mohiddin2,*, M. Ashraf Bhat3, Zahoor Ahmed Baba4, Fehim Jeelani5, M. Anwar Bhat6, Sajad Un Nabi7, Burhan Hamid2, Saba Bandey8, Farhanaz Rasool9, Zakir Amin1, Ibrahim Al-Ashkar10,*, Muhammad Adnan11, Ayman El Sabagh12

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 3021-3041, 2023, DOI:10.32604/phyton.2023.030921

    Abstract One hundred twenty-five endophytic microorganisms were isolated from the roots, stems, and leaves of four prominent rice cultivars growing in temperate regions. Their potential to combat rice blast disease and promote plant growth was investigated. The dual culture tests highlighted the strong antagonistic activity of five fungal (ranging from 89%–70%) and five bacterial (72%–61%) endophytes. Subsequent examination focused on volatile compounds produced by selected isolates to counter the blast pathogen. Among these, the highest chitinase (13.76 µg mL−1) and siderophore (56.64%), was exhibited by Aspergillus flavus, and the highest HCN production was shown by Stenotrophomonas maltophilia (36.15 µM mL−1).

    Phyton-International Journal of Experimental Botany, Vol.92, No.10, pp. 2907-2920, 2023, DOI:10.32604/phyton.2023.030689

    Abstract The objective of this study was to investigate the effects of root cutting stress on the dynamic changes of endogenous hormone content and growth characteristics of Quercus variabilis roots, and to explore the physiological role of endogenous hormones in regulating root-crown interactions in the short term. The morphological characteristics and endogenous hormone contents of normal roots (no root cutting, CK) and cut roots (cut by 1/3 of the length of the main root, RP) were determined by liquid chromatography, which was combined with mass spectrometry at different levels of different developmental stages. The results showed that the root growth indexes… More >

    Selenium: A Game Changer in Plant Development, Growth, and Stress Tolerance, via the Modulation in Gene Expression and Secondary Metabolite Biosynthesis

    Ali Bandehagh1,*, Zahra Dehghanian2, Vahideh Gougerdchi1, Mohammad Anwar Hossain3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2301-2324, 2023, DOI:10.32604/phyton.2023.028586

    Abstract The presence of selenium (Se) is not widely established as crucial for crops, although it is commonly recognized as an important nutrient for animals as well as humans. Even so, it is inevitably accepted that Se usually contributes positively to the life cycle of plants. Previous findings suggested that small amounts of Se seem to have a productive role in growth and production. As a result, Se is assumed to function in multiple ways, primarily by influencing a variety of biochemical and physiological functions. Also, Se also acts as a plant antioxidant and pro-oxidant and confers tolerance against different abiotic… More >

    Abstract

    Understanding physiological responses in saline agriculture may facilitate wheat breeding programs. Based on a screening test, the Ningmai-14 (NM-14) and Yangmai-23 (YM-23) wheat cultivars were selected for further experiments to understand the underlying salinity tolerance mechanism. This study investigated the effects of five salinity levels such as Control (CK) = 0 (without NaCl stress), S1 = 0.20%, S2 = 0.25%, S3 = 0.30% and S4 = 0.35% of NaCl concentrations of soil on wheat plants. The results showed that increased salinity concentration reduced the growth and yield of wheat cultivars (NM-14 and YM-23). However, YM-23 (12.7%) yielded more than NM-14… More >

    Abstract Phytohormones play important roles in plant growth and development, and polyploids are thought to be an important method for plant breeding. However, the relationship between ploidy and phytohormone is still unclear. In this study, barley at three ploidy levels were produced by microspore culture. Therefore, we further analyzed the phytohormone content in the shoots and roots of the three kinds of barley materials to study the effect of ploidy on phytohormones accumulation and distribution. The results showed that Abscisic acid (ABA), gibberellin (GA), jasmonic acid (JA), auxin (IAA), salicylic acid (SA) and cytokinin (CTK) were successfully determined in shoots and… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.4, pp. 667-694, 2022, DOI:10.32604/phyton.2022.017365

    Abstract Salinity stress is a major threat to global food production and its intensity is continuously increasing because of anthropogenic activities. Wheat is a staple food and a source of carbohydrates and calories for the majority of people across the globe. However, wheat productivity is adversely affected by salt stress, which is associated with a reduction in germination, growth, altered reproductive behavior and enzymatic activity, disrupted photosynthesis, hormonal imbalance, oxidative stress, and yield reductions. Thus, a better understanding of wheat (plant) behavior to salinity stress has essential implications to devise counter and alleviation measures to cope with salt stress. Different approaches… More >

    Abstract Taro (Colocasia esculenta (L.) Schott) is an important crop in Africa, Southeast Asia, and subtropics and is used as a food and medicine. The purple color pigmentation is an appealing character in taro. We sampled taro corms of the cultivar ‘Lipu Taro’ at four developmental stages, including LPYS1 (without purple pigment, 50 days of development (DOD)), LPYS2 (very few purple pigments, 75 DOD), LPYS3 (moderate purple pigments, 115 DOD) and LPYS4 (high purple pigments, 205 DOD). The purpose of our study was to identify the key genes underpinning the purple pigmentation in taro based on RNA-sequencing. Through RNA-Seq, 6453 differentially… More >

    Phyton-International Journal of Experimental Botany, Vol.90, No.2, pp. 515-531, 2021, DOI:10.32604/phyton.2021.013619

    Abstract The need for renewable energy sources makes microalgae an essential feedstock for biofuels production. The molecular aspects and the response to nitrogen (N)-limited conditions with a phytohormone stimulus in microalgae have been slightly explored. In this work, Scenedesmus obliquus was used as a study model to analyze the effect of benzyl amino purine (BAP) and gibberellic acid (GA) coupled to nitrogen limitation on cell growth, biomass and fatty acids. The selected 10-5 M BAP increased the biomass by 1.44-fold, and 10-6 M GA by 1.35-fold. The total lipids also increased by 2.8 and 1.11-fold, respectively. The 10-5 M BAP and… More >

    Abstract Objective and Patients: This study aimed to characterize bone mineral density abnormalities and pathophysiological associations in young adults living with a Fontan circulation.
    Design: Participants underwent bone mineral density measurement using dual‐energy X‐ray absorptiometry and serum biochemical analysis, cardiopulmonary exercise and strength testing and transthoracic echocardiography.
    Results: In our cohort (n = 28), 29% had osteopenic‐range bone mineral density and one patient was osteoporotic (average hip t score: −0.6 ± 1.1; spine t score: −0.6 ± 0.9). Four patients (14%) had z scores < −2.0. Parathyroid hormone levels were increased compared with laboratory median (6.1 ± 3.5 vs 4 pmol/L,… More >
