“…The studies by Bai et al 46 and Zhang et al 47 on the sprouting of Chinese sea buckthorn showed that the endogenous hormone (IAA, GA 3 , ZR ABA) content and ratio play a decisive regulatory role in the sprouting process. The study of sea buckthorn by Shah et al 7 showed that highest production of shoots from roots under in vitro conditions occurred in W4 medium (WPM medium with added IAA, benzyl adenine and giberellic acid) after pretreatment with high P in the presence of IAA while horizontal root production in WPM (Woody plant medium) was stimulated by IAA in low and middle P. These results indicate that hormone and nutrient elements interact during the root sprouting process of sea buckthorn. However, Bond 17 and Maschinski 48 pointed out that plants' response extent is related to the intensity of subjected disturbance.…”

“…This tree is widely used in medicine, food, beverage, cosmetics, and health products [1][2][3] . As a typical clonal plant, its lateral roots present a strong extending and branching ability and produces a large number of root suckers, which have the potential to ful l "one tree makes a forest" and achieve "eternal life and immortality" [4][5][6][7][8] . The coupling of clonal integration and nitrogen xation makes it more adaptable to arid and barren environments, forming a "sea buckthorn oasis" on a background of grasslands and deserts [9][10][11] .…”

Research into the relationship between coppice regeneration and stubble height has been mostly limited to stump sprouting, but root sprouts and clonal dispersal play a more important role in the restoration of declined populations and the maintenance of population stability. We aimed to investigate the response of root sprouting (number and growth) and the clonal dispersal (root extension and branching) capacity to stubble height, unveil its nutrient accumulation and allocation strategies and determine the appropriate stubble height that is most favorable for root sprouting, clonal dispersal, and nutrient accumulation. In a 15-year-old plantation of Hippophae rhamnoides ssp. sinensis with signs of premature aging, the plants were coppiced at 0, 10, and 20 cm from the ground level, with no coppicing as the control. The results showed the following: (1) Coppicing promoted the formation and growth of root sprouts, and root extension and branching, but promotion increased and then decreased with increasing stubble height, and the optimal stubble height was 10 cm. (2) N, P, K, Ca, and Mg content and reserves all increased and then decreased with the increase in stubble height, and the clonal nutrient content, reserves, and integrated nutrient accumulation capacity were greatest at 10 cm of stubble height. (3) The coppicing increased the accumulation and allocation ratio of nutrients in leaves, vertical roots, and horizontal roots, which played a dominant role in the integrated accumulation of clonal nutrients. (4) Root sprouting and clonal dispersal ability were positively correlated with clonal nutrient content, reserves, and integrated nutrient accumulation ability. Moreover, root-sprouting ability was positively correlated with clonal dispersal ability. From these, the coppicing regulated leaf development and clonal dispersal by affecting nutrient accumulation and allocation patterns, which in turn governed the formation and growth of root sprouts. This is a continuous driving process. According to the regression equations, a stubble height of 11–13 cm was estimated to be the most favorable for root sprouting, clonal dispersal, and nutrient accumulation.

Background and aims Global wheat production is under threat due to climate change, specifically from heat and drought, which are the major contributors. This study aims to address the response to drought in CIMMYT high temperature wheat lines, specifically analyzing root characteristics and their association with other parameters under water-stressed and well-watered conditions and different culture systems. Methods The variability of root traits of CIMMYT High Temperature Wheat Lines (HTWL) previously developed against heat stress and 10 Pakistani approved varieties was assessed under different culture conditions and water availability. Results Our findings revealed that the plasticity of the wheat root system is highly pronounced, with the conditions of the rhizosphere exerting a more substantial influence than the genotypic response. Furthermore, a small number of genotypes consistently exhibited desirable traits such as longer root systems and greater root biomass across different conditions. Persistent drought negatively affects root traits and reduces root growth. Conclusions The variation in root traits of HTWL against drought indicates their potential for the development of improved genotypes that can withstand multiple stresses. Furthermore, it is crucial to consider rhizosphere conditions when selecting genotypes, as the plasticity of wheat roots may lead to misinterpretations if rhizosphere conditions are disregarded. Therefore, for the selection of root traits under persistent drought conditions, it is recommended to evaluate a broader range of rhizosphere conditions.

Seabuckthorn (Hippophae sp.) is popularly known as the "Gold Rush" for its commercial value. It holds well-established vegetative propagation and in vitro regeneration techniques. Accordingly, micropropagation of Hippophae sp. from multiple explants follows the developmental stages of establishment, shoot proliferation, and rooting. The successful in vitro propagation protocols utilized Murashige and Skoog medium and Woody Plant Medium supplemented with cytokinin for shoot organogenesis, somatic embryogenesis, and auxins for high rooting frequency. Subsequent acclimatization of Hippophae sp. with a reasonable survival rate was recorded under greenhouse conditions. The genetic transformations in seabuckthorn are yet to be studied in detail. Still, initial studies were performed with conventional methods using Agrobacterium rhizogenes (indirect) and biolistics (direct), which could support extensive transformation research in the future for commercialization and conservation. This short review provides an overview of compiled works on the tissue culture of Hippophae rhamnoides and Hippophae salicifolia that could assist in further assessment and vast applications.
