Leaf shape diversity relies on transient morphogenetic activity in leaf margins. However, how this morphogenetic capacity is maintained is still poorly understood. Here, we uncover a role for the hormone cytokinin (CK) in the regulation of morphogenetic activity of compound leaves in tomato (Solanum lycopersicum). Manipulation of CK levels led to alterations in leaf complexity and revealed a un...

Abstract The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) their interactions on growth, flowering, composition Ervatamia coronaria plants. plants were fertilized monthly with NPK at rate 2, 4 6 g pot-1, in addition control Plants received treatments sprayed eit...

The soluble bean leaf auxin-binding protein (ABP) has a high affinity for a range of auxins including indole-3-acetic acid (IAA), alpha-napthaleneacetic acid, phenylacetic acid, 2,4,5-trichlorophenoxyacetic acid, and structurally related auxins. A large number of nonauxin compounds that are nevertheless structurally related to auxins do not displace IAA from bean ABP. Bean ABP has a high affini...

Apple (Malus x domestica) fruit size is dependent on cell division and expansion, processes that are subsequently regulated by plant hormones such as auxins, gibberellins, cytokinins. In this study, we investigated the role of expansion in apple growth identified which two was more deterministic final size. Three cultivars different sizes were selected, namely, “Twenty Ounce” (large-sized), “Ro...

Numerous studies on perennial crops have shown that almond has a low tolerance to climate change, which led detailed study for its adaptation by focusing selecting heat-tolerant varieties. The long period of agriculture creates particular challenges in changing climate. risk complicates the choice variety best current may be poorly suited future climates. Hence interest having large variability...

Abstract The endogenous level of cytokinins (CKs) and auxins (Auxs) was analyzed in isolated microspores ovaries two doubled haploid (DH) lines triticale (× Triticosecale Wittm.) to better understand the mechanism microspore embryogenesis (ME)—the most efficient widely applied method producing DHs. responsiveness studied ME significantly varied. induced by pre-treating tillers with low temperat...

Wild plant species are of great interest as a source pharmacologically valuable compounds but number them endemic and/or endangered ones. Modern biotechnology can provide reliable methods for their utilization without disturbing natural populations. In vitro culture Rhodiola being intensively developed to include into various biotechnological programmes. Aim. Development protocol direct rosea L...
